          Quản lý cơ sở dữ liệu website WordPress bằng phpMyAdmin      Cache   Translate Page   Web Page Cache   
Thiết kế Website Wordpress phpMyAdmin là một phần mềm nguồn mở cung cấp một giao diện người dùng đồ họa dựa trên web để quản lý cơ sở dữ liệu mySQL của bạn. Hầu hết các nhà cung cấp dịch vụ lưu trữ WordPress đều có phpMyAdmin được cài đặt trong bảng điều khiển của họ. Điều này cho phép người dùng dễ dàng truy cập cơ sở dữ liệu và thực hiện các nhiệm vụ quản lý cơ sở dữ liệu chung.

Tất cả các nhà cung cấp dịch vụ lưu trữ web được đề xuất của chúng tôi đều sử dụng cPanel. Để truy cập phpMyAdmin trong cPanel, di chuyển xuống đến Cơ sở dữ liệu và bấm vào phpMyAdmin. Điều này sẽ mở phpMyAdmin trong một tab trình duyệt mới
Bạn có thể thực hiện các tác vụ khác nhau từ phpMyAdmin như tìm / thay thế một từ nhất định trong bài đăng, sửa chữa cơ sở dữ liệu, tối ưu hóa cơ sở dữ liệu, thêm người dùng quản trị mới, tắt tất cả plugin, thay đổi mật khẩu v.v. v.v.

Lưu ý: Trước khi bạn thay đổi bất cứ điều gì, bạn phải thực hiện sao lưu cơ sở dữ liệu. Không có nút hoàn tác. Vì vậy, chỉ cần thực hiện sao lưu.

Tạo một bản sao lưu cơ sở dữ liệu WordPress bằng cách sử dụng phpMyAdmin
Để tạo bản sao lưu cơ sở dữ liệu WordPress của bạn từ phpMyAdmin, hãy nhấp vào Cơ sở dữ liệu WordPress của bạn. Trên menu trên cùng, nhấp vào tab Xuất .
Trong các phiên bản mới hơn của phpMyAdmin, nó sẽ hỏi bạn một phương thức xuất. Phương thức nhanh sẽ xuất cơ sở dữ liệu của bạn trong tệp .sql. Trong phương thức tùy chỉnh, nó sẽ cung cấp cho bạn nhiều tùy chọn hơn và khả năng tải xuống bản sao lưu trong kho lưu trữ nén zip hoặc gzip. Chúng tôi khuyên bạn nên sử dụng phương thức tùy chỉnh và chọn zip làm phương thức nén. Phương thức tùy chỉnh cũng cho phép bạn loại trừ các bảng khỏi cơ sở dữ liệu. Cho phép nói nếu bạn đã sử dụng một plugin tạo bảng bên trong cơ sở dữ liệu WordPress của mình, thì bạn có thể chọn loại trừ bảng đó khỏi bản sao lưu nếu bạn muốn.
Tệp cơ sở dữ liệu đã xuất của bạn có thể được nhập trở lại vào cơ sở dữ liệu khác hoặc cơ sở dữ liệu tương tự bằng cách sử dụng tab nhập của phpMyAdmin.
 
Thiết kế Web bán hàng bằng Wordpress  Tạo một bản sao lưu WordPress bằng cách sử dụng một Plugin
Giữ bản sao lưu thường xuyên của trang web WordPress của bạn là điều tốt nhất bạn có thể làm cho bảo mật WordPress của mình. Trong khi cơ sở dữ liệu WordPress chứa phần lớn thông tin trang web của bạn, nó vẫn thiếu một yếu tố khá quan trọng, hình ảnh. Tất cả hình ảnh của bạn được lưu trữ trong thư mục tải lên trong thư mục / wp-content / của bạn. Mặc dù cơ sở dữ liệu có thông tin mà hình ảnh được đính kèm trong bài đăng, nó sẽ vô dụng nếu thư mục hình ảnh không có các tệp đó.

Thường thì người mới bắt đầu nghĩ rằng sao lưu cơ sở dữ liệu là tất cả những gì họ cần. Nó không phải là sự thật. Bạn cần có bản sao lưu toàn bộ trang web bao gồm các chủ đề, plugin và hình ảnh của mình. KHÔNG, hầu hết công ty lưu trữ không giữ bản sao lưu hàng ngày .

Lưu ý: Nếu bạn đang sử dụng giải pháp lưu trữ được quản lý như WPEngine thì bạn không phải lo lắng. Họ chăm sóc sao lưu hàng ngày.

Đối với đa số chúng tôi không sử dụng WPEngine , bạn nên sử dụng một trong nhiều giải pháp có sẵn để giữ bản sao lưu thường xuyên cho trang web của mình.

Làm Website bán hàng bằng Wordpress Chúng tôi đang sử dụng VaultPress , một dịch vụ trả tiền hàng tháng, để giữ bản sao lưu thường xuyên của trang web của chúng tôi. Đối với những người yêu thích các plugin và không muốn trả phí định kỳ, chúng tôi khuyên bạn nên kiểm tra BackupBuddy , đây là giải pháp sao lưu hoàn chỉnh nhất cho WordPress.

Uptime & Performance


Feature-laden, value for money hosting packages are important, but nothing is of greater importance than your web host providing basic network reliability. Claims of 99.9% uptime are all well and good but only the select few can back up their promises with actual data.


Bluehost is proud of their network integrity and list it as one of their key features. No longer do webmasters need to worry about losing business because their site is down. In fact, downtime is one of the most prevalent reasons why site owners shift from mediocre providers to a company like Bluehost who take their commitment to 99.9% up-time very seriously.

Independent testing on a site hosted by Bluehost revealed only thirty minutes of total downtime over a 90-day period. What's really impressive about this result is that, out of the total downtime, all thirty minutes were identified as planned maintenance. Bluehost's planned downtime is always scheduled during periods when Web traffic is off-peak to keep impact to a minimum.

Visit Bluehost.com - 30 Day Money Back Guarantee. It's Risk Free!


A webmaster will always find any amount of downtime unpalatable but 30 minutes in 90 days equates to 99.93% uptime, which is a highly impressive result. Given that performance is a key factor in the choice of a web hosting provider, we decided to undertake some performance testing of our own. We tested the page load time of the Bluehost homepage .

Bluehost Results: 

Homepage is loaded in 3.4 seconds
Homepage is fully loaded in 5.1 seconds

(Test server region: Dallas, USA. Connection: Cable (5/1 Mbps, 30ms). Date: 11 August 2013)

Help & Support

Bluehost offers customers several ways to access their technical support, one of which is the Bluehost Help Center. The Help Center contains a complete database of troubleshooting issues and fixes, together with instructions for hundreds of site-management tasks. It's the quickest and easiest way to get minor issues resolved.
Alternatively, clients with more complex problems can submit a help ticket through the Help Center and will receive email or live support as needed. Tickets are always answered in less than 12 hours, with most being addressed within just 1-2 hours.

Lastly, Live Phone support is also offered 24/7. This allows customers to speak directly with a technical expert and have all their questions comprehensively answered. Clients outside of the United States have not been forgotten either with additional phone numbers being provided specifically for them.

          #36924: dbDelta(): Support more than one whitespace between field name and its type definition      Cache   Translate Page   Web Page Cache   

dbDelta() fails to remove multiple spaces between field name and field type definition in ALTER / CREATE statements. In result some table definitions may lead to constant ALTER statements to be executed which may easily crash MySQL server.

Compare:

Correct

$sql = "CREATE TABLE some_table (
    id bigint(20) NOT NULL KEY AUTO_INCREMENT,
    test varchar(100) NOT NULL,
    );";
require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
dbDelta($sql);

vs

Wrong, due to multiple spaces between 'test' and 'varchar' ALTER query is executed

$sql = "CREATE TABLE some_table (
    id bigint(20) NOT NULL KEY AUTO_INCREMENT,
    test  varchar(100) NOT NULL,
    );";
require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
dbDelta($sql);

Possible fix:

  • in dbDelta() call trim() on $tablefield->Type,
  • or remove extra spaces during preg_match:

replace:

preg_match("|".$tablefield->Field." ([^ ]*( unsigned)?)|i", $cfields[strtolower($tablefield->Field)], $matches);

with:

preg_match("|".$tablefield->Field."\s+([^ ]*( unsigned)?)|i", $cfields[strtolower($tablefield->Field)], $matches);

Apple macOS 10.14 ships with both a recent version of Apache (2.4.x), as well as php (7.1.x), so you’ll just have to install mysql and go through a few steps to get everything up and running.

Apache

First, you have to create a web root in your user account:

mkdir ~/Sites

Then add a configuration for your user:

sudo tee /etc/apache2/users/$USER.conf <<EOF <Directory "$HOME/Sites/"> Options Indexes MultiViews FollowSymLinks AllowOverride All Require all granted </Directory> EOF

Now we have to make sure that our user config above actually gets loaded:

sudo tee -a /etc/apache2/other/$USER-settings.conf <<EOF Include /private/etc/apache2/users/*.conf EOF

If you want to use vhosts, you’ll also have to make sure that the vhosts config gets loaded:

sudo tee -a /etc/apache2/other/$USER-settings.conf <<EOF Include /private/etc/apache2/extra/httpd-vhosts.conf EOF

After that, configure vhosts as necessary in /etc/apache2/extra/httpd-vhosts.conf (don’t forget to remove the examples in there).

It seems that mod_rewrite no longer gets loaded by default, so we’ll also add that to our config:

sudo tee -a /etc/apache2/other/$USER-settings.conf <<EOF LoadModule rewrite_module libexec/apache2/mod_rewrite.so EOF

PHP

PHP doesn’t get loaded by default. So we’ll also add it to our config:

sudo tee -a /etc/apache2/other/$USER-settings.conf <<EOF LoadModule php7_module libexec/apache2/libphp7.so EOF

You should also configure a few settings in /etc/php.ini :

sudo tee -a /etc/php.ini <<EOF date.timezone = "`sudo systemsetup -gettimezone | awk '{print $3}'`" display_errors = on error_reporting = -1 EOF

To activate these settings you have to restart Apache:

sudo apachectl restart

If you also need PEAR/PECL, followthese instructions.

MySQL

MySQL is not shipped with macOS, so we’ll have to install that manually. Instead of going for an installer package, we’ll use Homebrew . Once Homebrew is installed, installing MySQL is as simple as:

brew install mysql

If you want to start MySQL automatically, run:

brew services start mysql

          Speed up relationship queries in Laravel      Cache   Translate Page   Web Page Cache   

Adding indexes to your database tables is a great way to get some extra performance out of your application, especially if you have a large amount of data in your tables. They should be used sparingly and only on identified slow queries, as they have implications of their own such as increased table size and increased RAM usage. But those potential drawbacks are well worth it when you can get a query down from 3 seconds to 15 milliseconds with 5 minutes of work. The effects are particularly noticeable onpolymorphic / many to many polymorphic relationships.

The type of index created depends largely on the relationship type and the content structure.

One to one / one to many relationships Many to many relationships Polymorphic / many to many polymorphic relationships Creating indexes in Laravel

Adding indexes to your tables in Laravel is very straightforward. In your migrations you can add:

// Single index $table->index('video_id'); // Compound index $table->index(['commentable_type', 'commentable_id']);

See the Laravel documentation on indexes for more info.

One to one / one to many relationships

One to one and one to many relationships primarily work through foreign keys. Say we have 2 tables, users and addresses , where each user can have one address (one to one), the foreign key would be the user_id column on the addresses table. The same can be said for if a user can have multiple addresses (one to many).

For each of your foreign keys in your migration, you should let your database know that they are indeed foreign keys:

$table->unsignedInteger('user_id'); $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');;

You also get some extra benefits out of this by using foreign key constraints which will ensure data integrity, i.e. making sure you don't delete a profile which is being used by a user.

By default, mysql using the InnoDB storage engine will add an index automatically for foreign key fields, but if you're using a different set up, you can add one like this:

$table->index('user_id'); Many to many relationships

Many to many relationships require an extra table, known as a pivot table. Let's use the example from the Laravel docs of many users having many roles , where many users could share the role of administrator. Our table set up for this example would be something like this:

// users table $table->increments('id'); // roles table $table->increments('id'); // role_user pivot table $table->unsignedInteger('user_id'); $table->unsignedInteger('role_id');

As in the one to one relationship example above, we can use foreign keys to get all of the same benefits, but this time we can add two to our pivot table:

// role_user pivot table $table->unsignedInteger('user_id'); $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade'); $table->unsignedInteger('role_id'); $table->foreign('role_id')->references('id')->on('roles')->onDelete('cascade'); Bonus

As a bonus, if you want to make sure that a duplicate can never exist in your database for a combination of the user and role, you can add a unique constraint:

$table->unique(['user_id', 'role_id']); Polymorphic / many to many polymorphic relationships

Indexes really come into their own on the types of queries required for polymorphic relationships. I have seen queries that previously took 30 seconds to run to go all the way down to 100 milliseconds.

Let's start with another example. Our application this time has videos and posts , and each of them can have many comments . This is a polymorphic relationship: one post or video can have many comments. Our table set up would look like this:

// videos table $table->increments('id'); // posts table $table->increments('id'); // comments table $table->increments('id'); $table->text('comment_body'); $table->text('commentable_type'); $table->unsignedInteger('commentable_id');

Our index for this example is a bit different than the previous examples. Because almost every query we make on the comments table will include both the commentable_id and the commentable_type we need to create an index on the pair of them, this is called a compound index. To create this index we can pass two column names into the index method as an array.

// comments table $table->index(['commentable_id', 'commentable_type']);

The same index would apply if you were to use a many to many polymorphic relationship too, only you would apply it to your pivot table.

Order of fields in compound indexes

In terms of the performance, the order of the fields in the compound index does matter. The rule of thumb is to order them by whichever narrows down the results the most first. For example, given the following table:

commentable_id commentable_type 1 App\Video 2 App\Video 3 App\Video 1 App\Post 2 App\Post 3 App\Post

Say we want to run a query to get the comments for a Video with the id 1 .

If we were to create an index using $table->index(['commentable_type', 'commentable_id']); , the index will first filter on commentable_type , which would reduce the results to 3 items: commentable_id commentable_type 1 App\Video 2 App\Video 3 App\Video

And then by commentable_id , which would reduce our set to 1:

commentable_id commentable_type 1 App\Video Conversely, if we create our index using $table->index(['commentable_id', 'commentable_type']); , the index will first filter on commentable_id , which would reduce the results to 2 items: commentable_id commentable_type 1 App\Video 1 App\Post

And then by commentable_type , which would reduce our set to 1 again, getting the same result.

This contrived example demonstrates that filtering by commentable_id first makes the second filter - by commentable_type - quicker because it has fewer items to look through.

The order you choose completely depends on your content. If you're likely to have few comments on many commentable items then it's going to be better to filter on commentable_type first. But, as in our example, if you have few commentable items, but many comments on that item then it's going to be better to filter on commentable_id first.

Don't worry though, whichever you choose is going to be a performance win over not having an index at all.

Further

If you'd like to learn more about indexes, I highly recommend the Performant Laravel course on Servers for Hackers. It's free and includes 3 videos on indexing in MySQL as well a bunch of other useful performance tips.


          Login with GitHub OAuth API using PHP      Cache   Translate Page   Web Page Cache   

GitHub provides a web-based hosting service for version control. It plays an important role in software and web development. Presently GitHub has over 28 million users from around the world. If you want to allow users to log in with their social account, GitHub can be the best option beside the other social networks. GitHub OAuth Login is a quick and powerful way to integrate user login system in the web application.

GitHub authentication API allows the users to sign in to the website using their GitHub account without registration on your website. Login with GitHub account can be easily implemented using GitHub OAuth API. In this tutorial, we will show you how to integrate user login and registration system with GitHub using php and store the user’s profile data in the mysql database.

Before getting started, take a look the files structure to implement GitHub Login with PHP .


Login with GitHub OAuth API using PHP
Create GitHub OAuth Application

You need to create and register OAuth App to access GitHub API. Also, the Client ID & Client Secret need to be specified at the time of GitHub API call. Follow the below steps to create and configure GitHub OAuth application.

Login to your GitHub account . In the upper-right corner, click your profile picture and then click Settings .
Login with GitHub OAuth API using PHP
In the settings page, click Developer settings on the left sidebar.
Login with GitHub OAuth API using PHP
In the left sidebar, click OAuth Apps . To create new OAuth app, click the Register a new application .
Login with GitHub OAuth API using PHP
Enter all the necessary information (Application name, Homepage URL, Application description, and Authorization callback URL) to register your new OAuth application. Click Register application when you’re done.
Login with GitHub OAuth API using PHP
Client ID and Client Secret of the application will be generated. Copy the GitHub OAuth details (Client ID and Client Secret) for later use in the script to access GitHub API.
Login with GitHub OAuth API using PHP
Create Database Table

To store the user’s profile information from the GitHub account, a table needs to be created in the database. The following SQL creates a users table with some basic fields in the MySQL database.

CREATE TABLE `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`oauth_provider` enum('','github','facebook','google','twitter') COLLATE utf8_unicode_ci NOT NULL,
`oauth_uid` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
`name` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
`username` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
`email` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
`location` varchar(100) COLLATE utf8_unicode_ci DEFAULT NULL,
`picture` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`link` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`created` datetime NOT NULL,
`modified` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; Github OAuth Client for PHP (Github_OAuth_Client.php)

The Github_OAuth_Client is a PHP library that supports OAuth for GitHub REST API.

getAuthorizeURL() Generate URL to authorize with the Github account. getAccessToken() Exchange oauth code and get access token from Github OAuth API. apiRequest() Make an API call and retrieve the access token or user’s account data using from Github OAuth API. <?php /* * Class Github_OAuth_Client * * Author: CodexWorld * Author URL: https://www.codexworld.com * Author Email: admin@codexworld.com * * The first PHP Library to support OAuth for GitHub REST API. */ class Github_OAuth_Client{ public $authorizeURL = "https://github.com/login/oauth/authorize"; public $tokenURL = "https://github.com/login/oauth/access_token"; public $apiURLBase = "https://api.github.com/"; public $clientID; public $clientSecret; public $redirectUri; /** * Construct object */ public function __construct(array $config = []){ $this->clientID = isset($config['client_id']) ? $config['client_id'] : ''; if(!$this->clientID){ die('Required "client_id" key not supplied in config'); } $this->clientSecret = isset($config['client_secret']) ? $config['client_secret'] : ''; if(!$this->clientSecret){ die('Required "client_secret" key not supplied in config'); } $this->redirectUri = isset($config['redirect_uri']) ? $config['redirect_uri'] : ''; } /** * Get the authorize URL * * @returns a string */ public function getAuthorizeURL($state){ return $this->authorizeURL . '?' . http_build_query([ 'client_id' => $this->clientID, 'redirect_uri' => $this->redirectUri, 'state' => $state, 'scope' => 'user:email' ]); } /** * Exchange token and code for an access token */ public function getAccessToken($state, $oauth_code){ $token = self::apiRequest($this->tokenURL . '?' . http_build_query([ 'client_id' => $this->clientID, 'client_secret' => $this->clientSecret, 'state' => $state, 'code' => $oauth_code ])); return $token->access_token; } /** * Make an API request * * @return API results */ public function apiRequest($access_token_url){ $apiURL = filter_var($access_token_url, FILTER_VALIDATE_URL)?$access_token_url:$this->apiURLBase.'user?access_token='.$access_token_url; $context = stream_context_create([ 'http' => [ 'user_agent' => 'CodexWorld GitHub OAuth Login', 'header' => 'Accept: application/json' ] ]); $response = @file_get_contents($apiURL, false, $context); return $response ? json_decode($response) : $response; } } User Class (User.class.php)

The User class handles the database related operations (fetch, insert, and update). Specify the database host ( $dbHost ), username ( $dbUsername ), password ( $dbPassword ), and name ( $dbName ) as per your MySQL database credentials.

__construct() Connect to the database. checkUser() Check whether the user data already exists in the database. Update if user data exists, otherwise insert user’s profile data in the users table using PHP and MySQL. <?php /* * Class User * * Author: CodexWorld * Author URL: https://www.codexworld.com * Author Email: admin@codexworld.com * * Handles database related works */ class User { private $dbHost = "localhost"; private $dbUsername = "root"; private $dbPassword = "root"; private $dbName = "codexworld"; private $userTbl = 'users'; function __construct(){ if(!isset($this->db)){ // Connect to the database $conn = new mysqli($this->dbHost, $this->dbUsername, $this->dbPassword, $this->dbName); if($conn->connect_error){ die("Failed to connect with MySQL: " . $conn->connect_error); }else{ $this->db = $conn; } } } function checkUser($userData = array()){ if(!empty($userData)){ // Check whether user data already exists in database $prevQuery = "SELECT * FROM ".$this->userTbl." WHERE oauth_provider = '".$userData['oauth_provider']."' AND oauth_uid = '".$userData['oauth_uid']."'"; $prevResult = $this->db->query($prevQuery); if($prevResult->num_rows > 0){ // Update user data if already exists $query = "UPDATE ".$this->userTbl." SET name = '".$userData['name']."', username = '".$userData['username']."', email = '".$userData['email']."', location = '".$userData['location']."', picture = '".$userData['picture']."', link = '".$userData['link']."', modified = NOW() WHERE oauth_provider = '".$userData['oauth_provider']."' AND oauth_uid = '".$userData['oauth_uid']."'"; $update = $this->db->query($query); }else{ // Insert user data $query = "INSERT INTO ".$this->userTbl." SET oauth_provider = '".$userData['oauth_provider']."', oauth_uid = '".$userData['oauth_uid']."', name = '".$userData['name']."', username = '".$userData['username']."', email = '".$userData['email']."', location = '".$userData['location']."', picture = '".$userData['picture']."', link = '".$userData['link']."', created = NOW(), modified = NOW()"; $insert = $this->db->query($query); } // Get the user data from the database $result = $this->db->query($prevQuery); $userData = $result->fetch_assoc(); } // Return the user data return $userData; } } Github OAuth API Configuration (gitConfig.php)

In the gitConfig.php file, the Github OAuth PHP Client library is initialized to connect with Github API and working with SDK. Specify the client ID ( $clientID ) and client secret ( $clientSecret ) as per your GitHub OAuth application. Also, specify the redirect URL ( $redirectURL ) as per your script location.

<?php // Start session if(!session_id()){ session_start(); } // Include Github client library require_once 'src/Github_OAuth_Client.php'; /* * Configuration and setup GitHub API */ $clientID = 'Your_App_Client_ID'; $clientSecret = 'Your_App_Client_Secret'; $redirectURL = 'https://www.codexworld.com/github-login/'; $gitClient = new Github_OAuth_Client(array( 'client_id' => $clientID, 'client_secret' => $clientSecret, 'redirect_uri' => $redirectURL, )); // Try to get the access token if(isset($_SESSION['access_token'])){ $accessToken = $_SESSION['access_token']; } Login & Fetch GitHub Profile Data (index.php)

If the user already logged in with the GitHub account, the profile information (account ID, name, username, email, location, profile picture, and profile link) will display, otherwise, GitHub login button will appear.

If the access token already exists in the SESSION, the following happens: apiRequest() checkUser() If code parameter exists in the query string of the URL, the following happens: getAccessToken() Otherwise: getAuthorizeURL() <?php // Include GitHub API config file require_once 'gitConfig.php'; // Include and initialize user class require_once 'User.class.php'; $user = new User(); if(isset($accessToken)){ // Get the user profile info from Github $gitUser = $gitClient->apiRequest($accessToken); if(!empty($gitUser)){ // User profile data $gitUserData = array(); $gitUserData['oauth_provider'] = 'github'; $gitUserData['oauth_uid'] = !empty($gitUser->id)?$gitUser->id:''; $gitUserData['name'] = !empty($gitUser->name)?$gitUser->name:''; $gitUserData['username'] = !empty($gitUser->login)?$gitUser->login:''; $gitUserData['email'] = !empty($gitUser->email)?$gitUser->email:''; $gitUserData['location'] = !empty($gitUser->location)?$gitUser->location:''; $gitUserData['picture'] = !empty($gitUser->avatar_url)?$gitUser->avatar_url:''; $gitUserData['link'] = !empty($gitUser->html_url)?$gitUser->html_url:''; // Insert or update user data to the database $userData = $user->checkUser($gitUserData); // Put user data into the session $_SESSION['userData'] = $userData; // Render Github profile data $output = '<h2>Github Profile Details</h2>'; $output .= '<img src="'.$userData['picture'].'" />'; $output .= '<p>ID: '.$userData['oauth_uid'].'</p>'; $output .= '<p>Name: '.$userData['name'].'</p>'; $output .= '<p>Login Username: '.$userData['username'].'</p>'; $output .= '<p>Email: '.$userData['email'].'</p>'; $output .= '<p>Location: '.$userData['location'].'</p>'; $output .= '<p>Profile Link : <a href="'.$userData['link'].'#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000" target="_blank">Click to visit GitHub page</a></p>'; $output .= '<p>Logout from <a href="logout.php">GitHub</a></p>'; }else{ $output = '<h3 style="color:red">Some problem occurred, please try again.</h3>'; } }elseif(isset($_GET['code'])){ // Verify the state matches the stored state if(!$_GET['state'] || $_SESSION['state'] != $_GET['state']) { header("Location: ".$_SERVER['PHP_SELF']); } // Exchange the auth code for a token $accessToken = $gitClient->getAccessToken($_GET['state'], $_GET['code']); $_SESSION['access_token'] = $accessToken; header('Location: ./'); }else{ // Generate a random hash and store in the session for security $_SESSION['state'] = hash('sha256', microtime(TRUE) . rand() . $_SERVER['REMOTE_ADDR']); // Remove access token from the session unset($_SESSION['access_token']); // Get the URL to authorize $loginURL = $gitClient->getAuthorizeURL($_SESSION['state']); // Render Github login button $output = '<a href="'.htmlspecialchars($loginURL).'"><img src="images/github-login.png"></a>'; } ?>

Our GitHub OAuth PHP Library helps to integrate Login with Github in PHP. You can easily implement the Github OAuth login system in the web application. Also, the example code functionality can be extended as per your application needs. We also recommend you to add other social accounts in PHP login system for providing a user-friendly way to allow the user to login to your website.

          Entity query webform submission data condition       Cache   Translate Page   Web Page Cache   

Hi,

I'm trying to use entity query to select webformsubmisisons that contain a value in a textfield. My question is how should I call the data-fields?

If I use this condition (ticket_for = field name):
->condition('data.ticket_for',$ADPlusName);
I get this error:

Error: Call to a member function getColumns() on boolean in Drupal\Core\Entity\Query\Sql\Tables->addField() (line 227 of /www/sites/chiro8/chiroD8/web/core/lib/Drupal/Core/Entity/Query/Sql/Tables.php)

These condtions:

Give this error:

          A Review of MongoDB Backup Options      Cache   Translate Page   Web Page Cache   

Database backup is nothing but a way to protect or restore data. It is the process of storing the operational state, architecture, and data of your database. It can be very useful in situations of technical outage or disaster. So it is essential to keep the backup of your database and that your database has a good and easy process for backup.

MongoDB provides several tools/techniques to backup your databases easily.

In this article, we will discuss some of the top MongoDB backup and restore workflows.

Generally, there are three most common options to backup your MongoDB server/cluster.

Mongodump/Mongorestore MongoDB Cloud Manager Database Snapshots

Apart from these general options, there are other ways to backup your MongoDB. We will discuss all these options as well in this article. Let’s get started.

MongoDump/MongoRestore

If you have a small database (<100GB) and you want to have full control of your backups, then Mongodump and Mongorestore are your best options. These are mongo shell commands which can be used to manually backup your database or collections. Mongodump dumps all the data in Binary JSON(BSON) format to the specified location. Mongorestore can use this BSON files to restore your database.

Backup a Whole Database $ sudo mongodump --db mydb --out /var/backups/mongo

Output:

2018-08-20T10:11:57.685-0500 writing mydb.users to /var/backups/mongo/mydb/users.bson 2018-08-20T10:11:57.907-0500 writing mydb.users metadata to /var/backups/mongo/mydb/users.metadata.json 2018-08-20T10:11:57.911-0500 done dumping mydb.users (25000 documents) 2018-08-20T10:11:57.911-0500 writing mydb.system.indexes to /var/backups/mongo/mydb/system.indexes.bson

In this command, the most important argument is --db. It specifies the name of the database that you want to backup. If you don’t specify this argument then the Mongodump command will backup all your databases which can be very intensive process.

Backup a Single Collection $ mongodump -d mydb -o /var/backups/mongo --collection users

This command will backup only users collection in mydb database. If you don’t give this option then, it will backup all the collection in the database by default.

Taking Regular Backups Using Mongodump/Mongorestore

As a standard practice, you should be making regular backups of your MongoDB database. Suppose you want to take a backup every day at 3:03 AM, then in a linux system you can do this by adding a cron entry in crontab.

$ sudo crontab -e

Add this line in crontab:

3 3 * * * mongodump --out /var/backups/mongo Restore a Whole Database

For restoring the database, we can use Mongorestore command with --db option. It will read the BSON files created by Mongodump and restore your database.

$ sudo mongorestore --db mydb /var/backups/mongo/mydb

Output

2018-07-20T12:44:30.876-0500 building a list of collections to restore from /var/backups/mongo/mydb/ dir 2018-07-20T12:44:30.908-0500 reading metadata file from /var/backups/mongo/mydb/users.metadata.json 2018-07-20T12:44:30.909-0500 restoring mydb.users from file /var/backups/mongo/mydb/users.bson 2018-07-20T12:45:01.591-0500 restoring indexes for collection mydb.users from metadata 2018-07-20T12:45:01.592-0500 finished restoring mydb.users (25000 documents) 2018-07-20T12:45:01.592-0500 done Restore a whole collection

To restore just a single collection from db, you can use the following command:

$ mongorestore -d mydb -c users mydb/users.bson

If your collection is backed up in JSON format instead of BSON then you can use the following command:

$ mongoimport --db mydb --collection users --file users.json --jsonArray Advantages Very simple to use You have full access to your backup You can put your backups at any location like NFS shares, AWS S3 etc. Disadvantages Every time it will take a full backup of the database, not just the difference. For large databases, it can take hours to backup and restore the database. It’s not point-in-time by default, which means that if your data changes while backing it up then your backup may result in inconsistency. You can use --oplog option to resolve this problem. It will take a snapshot of the database at the end of mongodump process. MongoDB Ops Manager

Ops Manager is a management application for MongoDB which runs in your data center. It continuously backs up your data and provides point-in-time restore processes for your database. Within this application, there is an agent which connects to your MongoDB instances. It will first perform an initial sync to backup the current state of the database. The agent will keep sending the compressed and encrypted oplog data to Ops Manager so that you can have a continuous backup. Using this data, Ops Manager will create database snapshots. It will create a snapshot of your database every 6 hours and oplog data will be stored for 24 hours. You can configure the snapshot schedule anytime using the Ops Manager.

Advantages It’s point-in-time by default Doesn’t impact the production performance except for initial sync Support for consistent snapshots of sharded clusters Flexibility to exclude non-critical collections Disadvantages Network latency increases with the snapshot size while restoring the database. MongoDB Cloud Manager

MongoDB Cloud Manager is cloud-based backup solution which provides point-in-time restore, continuous and online backup solution as a fully managed service. You can simply install the Cloud Manager agent to manage backup and restore of your database. It will store your backup data in MongoDB cloud.

Advantages Very simple to use. Good GUI. Continuous backup of queries and oplog. Disadvantages No control on backup data. It is stored in MongoDB cloud. Cost depends on the size of the data and the amount of oplog changes. Restore process is slow. Snapshot Database Files

This is the simplest solution to backup your database. You can copy all the underlying files (content of data/ directory) and place it to any secure location. Before copying all the files, you should stop all the ongoing write operations to a database to ensure the data consistency. You can use db.fsyncLock() command to stop all the write operations.

There are two types of snapshots: one is cloud level snapshots and another is OS level snapshots.

If you are storing database data with a cloud service provider like AWS then you have to take AWS EBS snapshots for backup. In contrast, if you are storing DB files in native OS like Linux then you have to take LVM snapshots. LVM snapshots are not portable to other machines. So cloud bases snapshots are better than OS based snapshots.

Advantages Easy to use. Full control over snapshots. You can move it to any data center. These snapshots are diff snapshots which store only the differences from previous snapshots. No need to download the snapshots for restoring your database. You can just create a new volume from your snapshot. Disadvantages Using this method, you can only restore your database at breakup points. Maintenance becomes very complex sometimes. To coordinate backups across all the replica sets (in sharded system), you need a special devops team.

MongoDB Consistent Backup tool

MongoDB consistent backup is a tool for performing consistent backups of MongoDB clusters. It can backup a cluster with one or many shards to a single point of the database. It uses Mongodump as a default backup method. Run the following command to take backup using this tool.

$ mongodb-consistent-backup -H localhost -P 27017 -u USERNAME -p PASSWORD -l /var/backups/mongo

All the backups generated by this commands are MongoRestore compatible. You can user mongorestore command with --oplogReplay option to ensure consistency.

$ mongorestore --host localhost --port 27017 -u USERNAME -p PASSWORD --oplogReplay --dir /var/backups/mongo/mydb/dump Advantages Fully open source Works with sharded cluster Provides an option for remote backup such as Amazon S3 Auto-scaling available Very easy to install and run Disadvantage Not fully mature product Very few remote upload options Doesn’t support data encryption before saving to disk Official code repository lacks proper testing ClusterControl Backup

ClusterControl is an all in one automated database management system. It lets you monitor, deploy, manage & scale your database clusters with ease. It supports mysql, MongoDB, PostgreSQL, Percona XtraDB and Galera Cluster. This software automates almost all the database operations like deploying a cluster, adding or removing a node from any cluster, continuous backups, scaling the cluster etc. All these things, you can do from one single GUI provided by the ClusterControl system.

ClusterControl provides a very nice GUI for MongoDB backup management with support for scheduling and creative reports. It gives you two options for backup methods.

Mongodump Mongodb consistent backup

So users can choose any option according to their needs. This tool assigns a unique ID to all the backups and stores it under this path: ClusterControl > Settings > Backup > BackupID. If the specified node is not live while taking the backup then the tool will automatically find the live node from the cluster and carry on the backup process on that node. This tool also provides an option for scheduling the backups using any of the above backup methods. You can enable/disable any scheduling job by just toggling a button. ClusterControl runs the backup process in background so it won’t affect the other jobs in the queue.

Advantages Easy installation and very simple to use Multiple options for backup methods Backup scheduling is very easy using a simple GUI form Automated backup verification Backup reports with status Disadvantage Both backup methods internally use mongodump, which has some issues with handling very large databases. Conclusion

A good backup strategy is a critical part of any database management system. MongoDB offers many options for backups and recovery/restore. Along with a good backup method, it is very important to have multiple replicas of the database. This helps to restore the database without having the downtime of even one second. Sometimes for larger databases, the backup process can be very resource intensive. So your server should be equipped with good CPU, RAM, and more disk space to handle this kind of load. The backup process can increase the load on the server because of these reasons so you should run the backup process during the nights or non-peak hours.


          MySQL 8.0 InnoDB Cluster the quick hands-on manual      Cache   Translate Page   Web Page Cache   

I’m just back from a trip in Barcelona where I presented mysql 8.0 InnoDB Cluster (at dataops and Barcelona MySQL Meetup ) and the majority of feedback was great, but I also had some comments on the demos I showed. The first one was:


MySQL 8.0 InnoDB Cluster   the quick hands-on manual

This is a joke of course (maybe it’s true for some), people found it very easy and they liked it.

But then, the second one was that all I showed wasn’t easy to find, some people who already played with the solution didn’t succeeded in creating a cluster so easily… not because they had errors or encountered bugs, but more because they just didn’t know how to do it.

The goal of this blog post is to illustrate how to create a MySQL 8.0 InnoDB Cluster very quickly using the new MySQL Shell only !

Initial environment

We have 3 MySQL 8.0.11 instances running: mysql1 , mysql2 and mysql3

They can all communicate to each others and they have a user with all privileges created on each of them : clusteradmin .

Nothing else has been changed, no configuration file has been modified. The only important thing is that if you have created the admin user on them individually, just run RESET MASTER on all the instances.

Quick Cluster Creation

Let’s connect to one instance (doesn’t matter which one), and let’s create the cluster. I will list all commands needed to create the cluster very quickly and on a next post I will explain them in more details:

Connection using the Shell MySQL JS> \c clusteradmin@mysql1
Creating a session to 'clusteradmin@mysql1'
Enter password: ****
Fetching schema names for autocompletion... Press ^C to stop.
Your MySQL connection id is 10 (X protocol)
Server version: 8.0.11 MySQL Community Server - GPL
No default schema selected; type \use to set one.
MySQL [mysql1+ ssl] JS> MySQL Configuration MySQL [mysql1+ ssl] JS> dba.configureInstance('clusteradmin@mysql1',{'restart': true})

You will prompted to validate the changes and if a restart of MySQL is required, it will happen (if you use a default MySQL installation, 3 settings will be changed and a restart will be required) .

And you need to configure all the other nodes that you want to be part of the cluster:

MySQL [mysql1+ ssl] JS> dba.configureInstance('clusteradmin@mysql2',{'restart': true})
MySQL [mysql1+ ssl] JS> dba.configureInstance('clusteradmin@mysql3',{'restart': true}) Cluster Creation

When the servers are restarted, just connect again to one of them using the Shell and create the cluster:

MySQL [mysql1+ ssl] JS> \c clusteradmin@mysql1
MySQL [mysql1+ ssl] JS> cluster=dba.createCluster('MyCluster')

Now you already have a cluster but with only one membere, you can verify this using the status() method of the cluster object we created:

MySQL [mysql1+ ssl] JS> cluster.status()
{
"clusterName": "MyCluster",
"defaultReplicaSet": {
"name": "default",
"primary": "mysql1:3306",
"ssl": "REQUIRED",
"status": "OK_NO_TOLERANCE",
"statusText": "Cluster is NOT tolerant to any failures.",
"topology": {
"mysql1:3306": {
"address": "mysql1:3306",
"mode": "R/W",
"readReplicas": {},
"role": "HA",
"status": "ONLINE"
}
}
},
"groupInformationSourceMember": "mysql://clusteradmin@mysql1:3306"
} Add the other members

Now it’s time to add the 2nd and 3rd member to the new cluster:

MySQL [mysql1+ ssl] JS> cluster.addInstance('clusteradmin@mysql2:3306')
MySQL [mysql1+ ssl] JS> cluster.addInstance('clusteradmin@mysql3:3306')

Please, pay attention that here the port for MySQL standard protocol ( 3306 ) is required.

Check the cluster

We can verify our cluster using again the status() method:

MySQL [mysql1+ ssl] JS> cluster.status()
{
"clusterName": "MyCluster",
"defaultReplicaSet": {
"name": "default",
"primary": "mysql1:3306",
"ssl": "REQUIRED",
"status": "OK",
"statusText": "Cluster is ONLINE and can tolerate up to ONE failure.",
"topology": {
"mysql1:3306": {
"address": "mysql1:3306",
"mode": "R/W",
"readReplicas": {},
"role": "HA",
"status": "ONLINE"
},
"mysql2:3306": {
"address": "mysql2:3306",
"mode": "R/O",
"readReplicas": {},
"role": "HA",
"status": "ONLINE"
},
"mysql3:3306": {
"address": "mysql3:3306",
"mode": "R/O",
"readReplicas": {},
"role": "HA",
"status": "ONLINE"
}
}
},
"groupInformationSourceMember": "mysql://clusteradmin@mysql1:3306"
}

And voilà ! We have a 3 node MySQL 8.0 InnoDB Cluster !

Minimal Commands Summary \c clusteradmin@mysql1 dba.configureInstance('clusteradmin@mysql1',{'restart': true}) dba.configureInstance('clusteradmin@mysql2',{'restart': true}) dba.configureInstance('clusteradmin@mysql3',{'restart': true}) \c clusteradmin@mysql1 dba.createCluster('MyCluster') cluster.addInstance('clusteradmin@mysql2:3306') cluster.addInstance('clusteradmin@mysql3:3306') follow me

          基于可靠消息方案的分布式事务(四):接入 Lottor 服务      Cache   Translate Page   Web Page Cache   

上一篇文章中,通过Lottor Sample介绍了快速体验分布式事务Lottor。本文将会介绍如何将微服务中的生产方和消费方服务接入Lottor。

场景描述

  • 生产方:User服务
  • 消费方:Auth服务
  • 事务管理方:Lottor Server

Lottor-Samples中的场景为:客户端调用User服务创建一个用户,用户服务的user表中增加了一条用户记录。除此之外,还会调用Auth服务创建该用户对应的角色和权限信息。

我们通过上面的请求流程图入手,介绍接入Lottor服务。当您启动好docker-compose中的组件时,会创建好两个服务对应的user和auth数据库。其中User和Auth服务所需要的初始化数据已经准备好,放在各自的classpath下,服务在启动时会自动初始化数据库,所需要的预置数据(如角色、权限信息)也放在sql文件中。

Lottor客户端API

Lottor Client中提供了一个ExternalNettyService接口,用以发送三类消息到Lottor Server:

  • 预提交消息
  • 确认提交消息
  • 消费完成消息
public interface ExternalNettyService {
    /**
     * pre-commit msgs
     *
     * @param preCommitMsgs
     */
    public Boolean preSend(List<TransactionMsg> preCommitMsgs);
    /**
     * confirm msgs
     *
     * @param success
     */
    public void postSend(Boolean success, Object message);
    /**
     * msgs after consuming
     *
     * @param msg
     * @param success
     */
    public void consumedSend(TransactionMsg msg, Boolean success);
}

预发送#preSend的入参为预提交的消息列表,一个生产者可能有对应的多个消费者;确认提交#postSend的入参为生产方本地事务执行的状态,如果失败,第二个参数记录异常信息;#consumedSend为消费方消费成功的发送的异步消息,第一个入参为其接收到的事务消息,第二个为消费的状态。

事务消息TransactionMsg

public class TransactionMsg implements Serializable {
    /**
     * 用于消息的追溯
     */
    private String groupId;
    /**
     * 事务消息id
     */
    @NonNull
    private String subTaskId;
    /**
     * 源服务,即调用发起方
     */
    private String source;
    /**
     * 目标方服务
     */
    private String target;
    /**
     * 执行的方法,适配成枚举
     */
    private String method;
    /**
     * 参数,即要传递的内容,可以为null
     */
    private Object args;
    /**
     * 创建时间
     */
    private Long createTime = Timestamp.valueOf(DateUtils.getCurrentDateTime()).getTime();
    /**
     * 操作结果信息
     */
    private String message;
    /**
     * 更新时间
     */
    private Long updateTime;
    /**
     * 是否消费,默认为否
     *
     * {@linkplain com.blueskykong.lottor.common.enums.ConsumedStatus}
     */
    private int consumed = ConsumedStatus.UNCONSUMED.getStatus();
	 
	 ...
}

在构建事务消息时,事务消息id、源服务、目标服务、目标方法和目标方法的传参args都是必不可少的。消费方消费完之后,将会设置consumed的状态,出现异常将会设置异常message信息。

生产方-User服务

创建用户时,需要创建对应的角色。生产方接入分为三步:

  • 发送预提交消息
  • 执行本地事务
  • 发送确认提交的消息

引入依赖

首先,需要引入Lottor客户端的依赖:

<dependency>
    <groupId>com.blueskykong</groupId>
    <artifactId>lottor-starter</artifactId>
    <version>2.0.0-SNAPSHOT</version>
</dependency>

发起调用

在UserService中定义了创建用户的方法,我们需要在执行本地事务之前,构造事务消息并预发送到Lottor Server(对应流程图中的步骤1)。如果遇到预发送失败,则直接停止本地事务的执行。如果本地事务执行成功(对应步骤3),则发送confirm消息,否则发送回滚消息到Lottor Server(对应步骤4)。

@Service
public class UserServiceImpl implements UserService {
    private static final Logger LOGGER = LoggerFactory.getLogger(UserServiceImpl.class);
	 //注入ExternalNettyService
    @Autowired
    private ExternalNettyService nettyService;
    @Autowired
    private UserMapper userMapper;
    @Override
    @Transactional
    public Boolean createUser(UserEntity userEntity, StateEnum flag) {
        UserRoleDTO userRoleDTO = new UserRoleDTO(RoleEnum.ADMIN, userEntity.getId());
		 //构造消费方的TransactionMsg
        TransactionMsg transactionMsg = new TransactionMsg.Builder()
                .setSource(ServiceNameEnum.TEST_USER.getServiceName())
                .setTarget(ServiceNameEnum.TEST_AUTH.getServiceName())
                .setMethod(MethodNameEnum.AUTH_ROLE.getMethod())
                .setSubTaskId(IdWorkerUtils.getInstance().createUUID())
                .setArgs(userRoleDTO)
                .build();
        if (flag == StateEnum.CONSUME_FAIL) {
            userRoleDTO.setUserId(null);
            transactionMsg.setArgs(userRoleDTO);
        }
        //发送预处理消息
        if (!nettyService.preSend(Collections.singletonList(transactionMsg))) {
            return false;//预发送失败,本地事务停止执行
        }
        //local transaction本地事务
        try {
            LOGGER.debug("执行本地事务!");
            if (flag != StateEnum.PRODUCE_FAIL) {
                userMapper.saveUser(userEntity);
            } else {
                userMapper.saveUserFailure(userEntity);
            }
        } catch (Exception e) {
        	  //本地事务异常,发送回滚消息
            nettyService.postSend(false, e.getMessage());
            LOGGER.error("执行本地事务失败,cause is 【{}】", e.getLocalizedMessage());
            return false;
        }
        //发送确认消息
        nettyService.postSend(true, null);
        return true;
    }
}

代码如上所示,实现不是很复杂。本地事务执行前,必然已经成功发送了预提交消息,当本地事务执行成功,Lottor Client将会记录本地事务执行的状态,避免异步发送的确认消息的丢失,便于后续的Lottor Server回查。

配置文件

lottor:
  enabled: true
  core:
    cache: true  
    cache-type: redis
    tx-redis-config:

    time-between-eviction-runs-millis: 5000
    username: root
    password: _123456_
    schema[0]: classpath:/user.sql

如上为User服务的部分配置文件,lottor.enabled: true开启Lottor 客户端服务。cache 开启本地缓存记录。cache-type指定了本地事务记录的缓存方式,可以为redis或者MongoDB。serializer为序列化和反序列化方式。tx-manager-id为对应的Lottor Server的服务名。

Lottor Server

多个微服务的接入,对Lottor Server其实没什么侵入性。这里需要注意的是,TransactionMsg中设置的source和target字段来源于lottor-common中的com.blueskykong.lottor.common.enums.ServiceNameEnum:

public enum ServiceNameEnum {
    TEST_USER("user", "tx-user"),
    TEST_AUTH("auth", "tx-auth");
	//服务名
    String serviceName;
	//消息中间件的topic
    String topic;
    
    ...
}

消息中间件的topic是在服务名的基础上,加上tx-前缀。消费方在设置订阅的topic时,需要按照这样的规则命名。Lottor Server完成的步骤为上面流程图中的2(成功收到预提交消息)和5(发送事务消息到指定的消费方),除此之外,还会定时轮询异常状态的事务组和事务消息。

消费方-Auth服务

引入依赖

<dependency>

引入了Lottor客户端starter,spring-cloud-stream用于消费方接收来自Lottor Server的事务消息。

@EnableBinding({TestSink.class})
public class ListenerStream extends InitStreamHandler {
    private static final Logger LOGGER = LoggerFactory.getLogger(ListenerStream.class);
    @Autowired
    private RoleUserService roleUserService;
    @Autowired
    public ListenerStream(ExternalNettyService nettyService, ObjectSerializer objectSerializer) {
        super(nettyService, objectSerializer);
    }
    @StreamListener(TestSink.INPUT)
    public void processSMS(Message message) {
        //解析接收到的TransactionMsg
        process(init(message));
    }
    @Transactional
    public void process(TransactionMsg message) {
        try {
            if (Objects.nonNull(message)) {
                LOGGER.info("===============consume notification message: =======================" + message.toString());
                if (StringUtils.isNotBlank(message.getMethod())) {
                    MethodNameEnum method = MethodNameEnum.fromString(message.getMethod());
                    LOGGER.info(message.getMethod());
                    //根据目标方法进行处理,因为一个服务可以对应多个生产方,有多个目标方法
                    switch (method) {
                        case AUTH_ROLE:
                            UserRoleDTO userRoleDTO = (UserRoleDTO) message.getArgs();
                            RoleEntity roleEntity = roleUserService.getRole(userRoleDTO.getRoleEnum().getName());
                            String roleId = "";
                            if (Objects.nonNull(roleEntity)) {
                                roleId = roleEntity.getId();
                            }
                            roleUserService.saveRoleUser(new UserRole(UUID.randomUUID().toString(), userRoleDTO.getUserId(), roleId));
                            LOGGER.info("matched case {}", MethodNameEnum.AUTH_ROLE);
                            break;
                        default:
                            LOGGER.warn("no matched consumer case!");
                            message.setMessage("no matched consumer case!");
                            nettyService.consumedSend(message, false);
                            return;
                    }
                }
            }
        } catch (Exception e) {
        	  //处理异常,发送消费失败的消息
            LOGGER.error(e.getLocalizedMessage());
            message.setMessage(e.getLocalizedMessage());
            nettyService.consumedSend(message, false);
            return;
        }
        //成功消费
        nettyService.consumedSend(message, true);
        return;
    }
}

消费方监听指定的topic(如上实现中,为test-input中指定的topic,spring-cloud-stream更加简便调用的接口),解析接收到的TransactionMsg。根据目标方法进行处理,因为一个服务可以对应多个生产方,有多个目标方法。执行本地事务时,Auth会根据TransactionMsg中提供的args作为入参执行指定的方法(对应步骤7),最后向Lottor Server发送消费的结果(对应步骤8)。

配置和User服务的差别在于增加了spring-cloud-stream的配置,配置了rabbitmq的相关信息,监听的topic为tx-auth。

小结

本文主要通过User和Auth的示例服务讲解了如何接入Lottor客户端。生产方构造涉及的事务消息,首先预发送事务消息到Lottor Server,成功预提交之后便执行本地事务;本地事务执行完则异步发送确认消息(可能成功,也可能失败)。Lottor Server根据接收到的确认消息决定是否将对应的事务组消息发送到对应的消费方。Lottor Server还会定时轮询异常状态的事务组和事务消息,以防因为异步的确认消息发送失败。消费方收到事务消息之后,将会根据目标方法执行对应的处理操作,最后将消费结果异步回写到Lottor Server。

          PHP set in HTML table      Cache   Translate Page   Web Page Cache   

I am trying to show all products in a database with a certain category in a HTML table. However I'm not sure how to limit the table to three columns only.

Here is my code:

<table> <?php $catagory=$_GET["q"]; $con = mysql_connect("localhost","cl49-XXX","XXX"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("cl49-XXX", $con)or die( "Unable to select database"); $result=mysql_query("SELECT * FROM products WHERE catagory = '$catagory' ")or die('You need enter a catagory ' ); for ($i = 0; $i < mysql_num_rows($result); $i++) { $row = mysql_fetch_array($result); $prodname = $row['prodname']; $prodID = $row['prodID']; if ($i % 5 == 0 || $i == 0) { echo "<tr>"; } echo " <td> <b>$prodname </b><br /> Product ID: $prodID<br /> <img src='/userpics/$prodID.jpg' height='200' width='200'> </td>"; if ($i % 3 == 0 || $i == (mysql_num_rows($result)-1)) { echo "</tr>"; } } ?> <table>

I am waiting to show prodID, prodtitle and image all in the same "cell" but only have three columns (three products per row).

How do I do this?

echo "<tr>"; // first row beginning for ($i = 1; $i <= mysql_num_rows($result); $i++) { $row = mysql_fetch_array($result); $prodname = $row['prodname']; $prodID = $row['prodID']; echo " <td> <b>$prodname </b><br /> Product ID: $prodID<br /> <img src='/userpics/$prodID.jpg' height='200' width='200'> </td>"; if ($i % 3 == 0) { echo "</tr> <tr>"; // it's time no move to next row } } echo "</tr>"; // last row ending

Note that $i is now starting from 1 and it loops while <= of num_rows, not < .

          发现CVE-2018-11512-wityCMS 0.6.1 持久型XSS      Cache   Translate Page   Web Page Cache   

Discovering CVE-2018-11512 - wityCMS 0.6.1 Persistent XSS

CMS(内容管理系统)很适合被用来做代码审计,尤其是现在CMS系统越来越流行,很多人愿意使用CMS搭建自己的项目。由于大部分CMS是一种开源项目,所以对于CMS的审计属于白盒测试,白盒测试让我们可以发现更多的安全漏洞,而且一旦我们发现了这些漏洞,由于其被广泛使用,所以它的漏洞的影响范围也是呈指数级增长的。这是因为通过白盒测试我们可以查看到程序的内部结构,从而更清楚的理解程序的工作原理。

WityCMS就是一个由creatiwiwiwiwiwity制作的CMS系统,它帮助管理不同用途的内容,如个人博客、商业网站或任何其他定制系统。在本文中,我将介绍如何设置CMS,查找web应用程序问题,以及如何复现CVE-2018-11512漏洞。

环境安装(windows下安装xampp)

  • 1.下载WityCMS0.6.1的源代码
  • 2.把/witycms-0.6.1 目录复制到C:\xampp\htdocs\ 下 或者是你自己安装xampp的的htdocs目录
  • 3.运行Apache和MySQL然后访问http://localhost/phpmyadmin/index.php.
  • 4.点击"databases"(中文版本的"数据库")
  • 5.创建一个名为"creatiwity_cms"的数据库

查找漏洞

因为这篇文章主要是关于CVE-2018-11512的,所以我今天就只找这个程序中的持久型XSS的洞,开始之前,我们先了解下什么是持久型XSS。

根据OWASP的介绍,"跨站脚本攻击(xss)是一种注入类型的攻击手段,它允许恶意web用户将代码植入到提供给其它用户使用的页面中"。这意味着只要一个网站上存在注入点,xss就可能被触发。目前有三种类型的XSS,但是本文我将讨论常见的XSS,即反射型XSS和持久型XSS。

当输入的数据被在发出请求后被返回给我们时,反射型XSS就会被触发。对于反射型XSS来说,网站的搜索功能可以作为一个测试反射型XSS的很好的例子。当用户在搜索框中输入一段payload后,该搜索功能可能会受到反射型XSS的影响。

另外,持久型XSS也被称为"存储型XSS"。这种类型的XSS值会被保存在系统中的某个数据库或是文件中。XSS的利用点通常存在于可以让用户随时更改的设置操作中,比如用户的个人信息页,可以设置用户的电子邮件,姓名,地址之类的地方。也可能存在于用户可以自己更改的某些系统设置中。

对于wityCMS,我的目标是找到可以在系统中保存数据的利用点。这基本上可以手工完成,也可以通过工具自动找到这些利用点。由于我已经在Windows中安装了它,所以我必须使用命令“findstr”而不是“grep”(抱歉,喜欢用"grep"的同学们)。可以在这里找到"findstr"的相关信息。

恶意代码的文件,我们可以使用以下命令:">要列出可以输入恶意代码的文件,我们可以使用以下命令:

/S = Recursive searching
/P = Skip files with non-printable characters
/I = Case insensitive
/N = Prints the line number
/c:<STR> = String to look for

代码:

findstr /SPIN /c:"<input" "c:\xampp\htdocs\witycms-0.6.1*.html"

命令行运行后的结果:

这个结果肯定很让人惊喜,因为可能存在XSS的地方太多了。登录到管理员面板后,我们可以轻松的在输入框中输入我们的payload。通过访问http://localhost/witycms-0.6.1/,我们可以看到一个很明显的值,如图所示:

我们安装这个CMS的时候设置了这个站点名称,它现在显示在主页上,不知道这个站点名称会不会存在持久型XSS,现在我们看看能不能在管理设置里修改这个值。

使用安装时设置的管理员账号密码登录到管理面板,登录后,管理面板中会有一个这样的小链接:

点击"Administration"后,网页会被重定向到我们安装时的执行设置操作的页面,第一个设置值也是网站名称。

插入一个非常简单的XSS代码试试:

script>alert(1)</script>

点击"save(保存)"后,返回值为:

可以注意到<script>和</script>标签被过滤了,因此我们可以知道该系统中存在一个防护机制,所以现在我们需要找到这个防护机制的运行原理。

当数据被保存到数据库中时,会处理一个请求。在这种情况下,我们应该能够识别请求方法是POST还是GET,在页面空白处右键单击"审查元素"查看源代码后,可以确认该方法是POST请求。

从这点来看,我们应该尝试找到POST请求发生的地方,这样顺下去我们就可以看到防护机制的运行点。因此,在cmd中输入以下命令:

findstr /SPIN /c:"$_POST" "c:\xampp\htdocs\witycms-0.6.1*.php"

这个命令类似于我们之前查找包含“input”标记的文件,但是这次,我们尝试在.php文件中查找引用"$_POST"的地方。

因为其他文件都与默认包含的库有关,这些都pass掉。所以命令的结果指向文WMain.hp,WRequest.php和WSession.php。浏览这些文件将我们发现在WRequest中有一个有趣的函数。如下所示,当防护机制发现脚本标示符时,这些标示符将被一个空字符串替换:

由于过滤器函数没有递归,所以过滤器只能拦截这样的输入:

所以输入这种内容是可以绕过过滤器的:

在我们设置站点名称的输入框中输入以下内容,我们将会得到以下结果:

一旦这个payload被设置为站点名称,访问网站的用户将会触发这个脚本,即使TA并没有经过身份验证。

这就开启了新世界的大门,因为当用户访问网站时会执行某些恶意脚本可能会造成比较严重的后果。比如可以将用户重定向到钓鱼站点,在用户不知情的情况下执行矿机脚本,或者其他很多操作。

处理CVE编号

由于这个bug容易引起安全问题,并且这个CMS正在被数以千计的人使用,所以我决定给这个程序申请一个CVE编号,以此来获得一个公开的CVE条目。

信息安全漏洞或者已经暴露出来的弱点给出一个公共的名称。cnas(cve-numbering-authorities)根据程序类型分别处理这些cve编号的漏洞。例如,如果联想设备中发现了安全问题,应该向联想的产品安全应急响应团队报告,在评估了漏洞后,他们将会给这个漏洞一个cve编号。">CVE 的英文全称是"Common Vulnerabilities & Exposures",CVE就好像是一个字典表,为广泛认同的计算机信息安全漏洞或者已经暴露出来的弱点给出一个公共的名称。CNAs(CVE Numbering Authorities)根据程序类型分别处理这些CVE编号的漏洞。例如,如果联想设备中发现了安全问题,应该向联想的产品安全应急响应团队报告,在评估了漏洞后,他们将会给这个漏洞一个CVE编号。

这说明,如果同样是在CNA公司的产品或项目中发现了漏洞,他们评估后可以直接给出一个CVE编号,在CNAs的CVE的漏洞列表中可以通过编号直接找到这个漏洞。而对于wityCMS, CreatiWity这两个产品,其创建者没有注册到CNA,所以我们可以向MITRE公司申请这个持久型XSS漏洞的CVE编号,下面是处理CVE漏洞事件的步骤:

  • 1.确认产品是否由CNA管理。如果由CNA管理,则报告该特定CNA的漏洞。如果不是,则报告给MITRE公司。
  • 2.通过google确认发现的漏洞是否已经分配了一个CVE编号。经常检查产品更新,以确认漏洞是否已经公开。
  • 3.对于wityCMS的情况,我使用了MITRE公司的CVE申请表单,可以在这里找到。
  • 4.在表格中填写所需的详细信息。关于wityCMS的这个漏洞,我是这样填的:
  • Vulnerability Type: Cross-Site Scripting
  • (漏洞类型:xss)
  • Product: wityCMS
  • (厂商:wityCMS)
  • Version: 0.6.1
  • (版本:0.6.1)
  • Vendor confirmed the vulnerability? No (Not acknowledged yet at the time - of request)
  • 厂商是否已确认该漏洞 没有 (漏洞提交时厂商未确认)
  • Attack Type: Remote
  • 攻击类型:远程
  • Impact: Code execution
  • (影响:代码执行)
  • Affected Components: Source code files showing “site_title” as output
  • 受影响的组件:输出"site_title"的源文件
  • Attack Vector: To exploit the vulnerability, one must craft and enter a script in the Site name field of the system
  • 攻击方式:必须在系统的站点名称字段中手工注入脚本
  • Suggested Description: Stored cross-site scripting (XSS) vulnerability in the "Website's name" field found in the "Settings" page under the "General" menu in Creatiwity wityCMS 0.6.1 allows remote attackers to inject arbitrary web script or HTML via a crafted website name by doing an authenticated POST HTTP request to admin/settings/general.
  • 漏洞详情:在creatiwitycms 0.6.1的“设置”菜单下的“网站名称”字段中存在存储型XSS漏洞,允许远程攻击者通过一个经过验证的POST HTTP请求向admin/ Settings / General注入任意的web脚本或HTML。

  • Reference(s): https://github.com/Creatiwity/wityCMS/issues/150, https://github.com/Creatiwity/wityCMS/co...229147de44
  • 参考

填写信息应该详细一点。为了让CVE处理的更快一些,描述中最好引用一些可以辅助理解漏洞的资料,并且详细地描述漏洞细节,如果可以,还应该写上漏洞可能有的修复方案。例如,在发送报告之前,我在这个项目的GitHub主页上发现了这个漏洞可能存在的点,因为有很多已经公开的关于存储型XSS的CVE漏洞,我找了其中的一个作为参考,然后通过这个漏洞想到了构造一个存储型XSS方法,并且注意到在这个GitHub项目中可能通过这个方法复现这个漏洞。

最后一点小贴士

  1. 如果细节已经公开,那么CVE号处理只需要一两天,所以最好先与开发人员或与项目相关的响应团队进行沟通,以便进行适当的修复。

          JSON API: Working with JSON API and Elasticsearch      Cache   Translate Page   Web Page Cache   

Hi,

Some context:
- We are building a decoupled Drupal 8 using JSON API.
- Our frontend App is using most of JSON API endpoints to build the frontend.
- We are also in the process of enabling Elasticsearch as our search engine.

Currently JSON API is (surely) executing all queries against MYSQL.

My question/concern is, once enabling/integrating Elasticsearch, is JSON API going to be able to switch and execute queries against Elasticsearch?

I apologize if it's an already answered question, but I'm a little bit lost regarding the capabilities of JSON API.

Thanks in advance,
Sharif.

We've previously shown you how to get a working local installation of Apache on your Windows PC. In this article, we'll show how to install PHP 5 as an Apache 2.2 module.

Why PHP?

PHP remains the most widespread and popular server-side programming language on the web. It is installed by most web hosts, has a simple learning curve, close ties with the MySQL database, and an excellent collection of libraries to cut your development time. PHP may not be perfect, but it should certainly be considered for your next web application. Both Yahoo and Facebook use it with great success.

Why Install PHP Locally?

Installing PHP on your development PC allows you to safely create and test a web application without affecting the data or systems on your live website. This article describes PHP installation as a module within the Windows version of Apache 2.2. Mac and Linux users will probably have it installed already.

All-in-One packages

There are some excellent all-in-one Windows distributions that contain Apache, PHP, MySQL and other applications in a single installation file, e.g. XAMPP (including a Mac version), WampServer and Web.Developer. There is nothing wrong with using these packages, although manually installing Apache and PHP will help you learn more about the system and its configuration options.

          Deploying a Stateful Application on Azure Kubernetes Service (AKS)      Cache   Translate Page   Web Page Cache   

Once you go through this Kubernetes tutorial, you’ll be able to follow the processes & ideas outlined here to deploy any stateful application on Azure Kubernetes Service (AKS).

In ourprevious post, we guided you through the process of deploying a stateful, Dockerized Node.js app on Google Cloud Kubernetes Engine! As an example application, we used our blog engine called Ghost. If you read that post, you'll see that the cluster creation, disk provisioning and the mysql database creation and handling is vendor specific, which also leaks into our Kubernetes objects. So let's compare it to setting up an AKS cluster on Azure and deploying our Ghost there.

This article was written byKristof Ivancza who is a software engineer at RisingStack &Tamas Kadlecsik, RisingStack's CEO. In case you need guidance with Kubernetes or Node.js, feel free to ping us at [emailprotected]

If you are not familiar with Kubernetes, I recommend reading our Getting started with Kubernetes article first.

What will we need to deploy a stateful app on Azure Kubernetes Engine? Create a cluster Persistent Disks to store our images and themes Create a MySQL instance and connect to it A secret to store credentials A deployment A service to expose the application Creating the Cluster

First, we need to create a cluster, set the default cluster for AKS and pass cluster credentials to kubectl.

# create an Azure resource group $ az group create --name ghost-blog-resource --location eastus # locations: eastus, westeurope, centralus, canadacentral, canadaeast # ------ # create a cluster $ az aks create --resource-group ghost-blog-resource --name ghost-blog-cluster --node-count 1 --generate-ssh-keys # this process could take several minutes # it will return a JSON with information about the cluster # ------ # pass AKS Cluster credentials to kubectl $ az aks get-credentials --resource-group ghost-blog-resource --name ghost-blog-cluster # make sure it works $ kubectl get node The Container and the Deployment

We'll use the same imageas before, and the Deployment will be the same as well. I'll add it to this blogpost though, so you can see how it looks like.

# deployment.yml apiVersion: apps/v1beta1 kind: Deployment metadata: name: ghost-blog labels: app: ghost-blog spec: replicas: 1 selector: matchLabels: app: ghost-blog template: metadata: labels: app: ghost-blog spec: containers: # ghost container - name: ghost-container image: ghost:alpine imagePullPolicy: IfNotPresent # ghost always starts on this port port: - containerPort: 2368 Creating Persistent Disks to Store our Images and Themes

We'll create our disk using Dynamic Provisioning again. Although, in this case, we won't specify the storageClassName , as Kubernetes will use the default one when it's omitted. We could have done this on GKE as well, but I wanted to provide a more detailed picture of the disk creation. On GKE the default StorageClass was called standard , on AKS it is called default .

# PersistentVolumeClaim.yml apiVersion: v1 kind: PersistentVolumeClaim metadata: name: pd-blog-volume-claim spec: accessModes: - ReadWriteOnce resources: requests: storage: 10Gi

Submit this yaml with the following command:

$ kubectl apply -f PersistentVolumeClaim.yml # make sure it is bound $ kubectl get pvc # it could take a few minutes to be bound, if its pending for more than a minute check `kubectl describe` to make sure nothing fishy happened $ kubectl describe pvc

The deployment should be updated as well, just as before:

# deployment.yml apiVersion: apps/v1beta1 kind: Deployment metadata: name: ghost-blog labels: app: ghost-blog spec: replicas: 1 selector: matchLabels: app: ghost-blog template: metadata: labels: app: ghost-blog spec: containers: # ghost container - name: ghost-container image: ghost:alpine imagePullPolicy: IfNotPresent # ghost always starts on this port ports: - containerPort: 2368 volumeMounts: # define persistent storage for themes and images - mountPath: /var/lib/ghost/content/ name: pd-blog-volume volumes: - name: pd-blog-volume persistentVolumeClaim: claimName: pd-blog-volume-claim Creating a MySQL Instance and Connecting to it Using SSL First we need to add the MySQL extension for Azure Databases. $ az extension add --name rdbms Now we're ready to create our MySQL server. $ az mysql server create --resource-group ghost-blog-resource --name ghost-database --location eastus --admin-user admin --admin-password password --sku-name GP_Gen4_2 --version 5.7 # this could take several minutes to complete Configuring the Firewall Rule $ az mysql server firewall-rule create --resource-group ghost-blog-resource --server ghost-database --name allowedIPrange --start-ip-address 0.0.0.0 --end-ip-address 255.255.255.255

This rule will give access to the database from every IP. It is certainly not recommended to open everything. However, the Nodes in our cluster will have different IP addresses which are difficult the guess ahead of time. If we know that we will have a set number of Nodes, let's say 3, we can specify those IP addresses. However, if we plan to use Node autoscaling, we will need to allow connections from a wide range of IPs. You can use this as a quick and dirty solution, but it is definitely better to use a Vnet.

Configure Vnet service endpoints for Azure Database for MySQL

Virtual Network (VNet) service endpoint rules for MySQL is a firewall security feature. By using it, we can limit access to our Azure MySQL server, so it only accepts requests that are sent from a particular subnet in a virtual network. Via using VNet rules, we don't have to configure Firewall Rules and add each and every node's IP to grant access to our Kubernetes Cluster.

$ az extension add --name rdbms-vnet # make sure it got installed $ az extensions list | grep "rdbms-vnet" { "extensionType": "whl", "name": "rdbms-vnet", "version": "10.0.0" }

The upcoming steps will have to be done in the browser as there is no way to do it through the CLI. Or even if there is, it is definitely not documented, so it is a lot more straightforward to do it on the UI.

Go toAzure Portal and login to your account In the search bar on the top search for Azure Database for MySQL servers . Select the database you created ( ghost-database ). On the left sidebar, click Connection Security You will find VNET Rules in the middle. Click + Adding existing virtual network Give it a name (e.g: myVNetSQLRule), Select your subscription type Under Virtual Network , select the created resource group and the s

          On InnoDB Data Compression in MySQL      Cache   Translate Page   Web Page Cache   

Another story that I've prepared back in April for my meeting with one of customers in London was a "compression story". We spent a lot of time on it in several support issues in the past, with only limited success.

In case of InnoDB tables, there are actually two ways to compress data (besides relying on filesystem compression or compressing individual columns at server or application side). Historically the first one was introduced by the Barracuda InnoDB file format and ROW_FORMAT=COMPRESSED it supported. Notable number of related bugs were reported with time, and it may be not that easy to identify them all (you can find current list of bugs tagged with "compression" here ). I've picked up the following bugs for my "story":

Bug #88220 - " compressing and uncompressing InnoDB tables seems to be inconsistent ". Over years Simon Mudd , Monty Solomon (see related Bug #70534 - " Removing table compression leaves compressed keys ") and other community members reported several bugs related to inconsistencies and surprises with key_block_size option. It is used for both MyISAM and InnoDB storage engines (for compressed tables) and it seems nobody is going to fix the remaining problems until they are gone with MyISAM engine. Bug #69588 - " MyISAM to InnoDB compressed slower than MyISAM to InnoDB, Then InnoDB to Compressed ". Just a detail to take into account, noted 5 years ago by Joffrey MICHAIE , verified almost 4 years ago and then getting zero public attention from Oracle engineers. Bug #62431 - " What is needed to make innodb compression work for 32KB pages? ". Nothing can be done according to the manual :

"In particular, ROW_FORMAT=COMPRESSED in the Barracuda file format assumes that the page size is at most 16KB and uses 14-bit pointers."

Bug #78827 - " Speedup replication of compressed tables ". Come on, Danil van Eeden , nobody cares that

"Replication and InnoDB compressed tables are not efficiently working together."

The bug is still "Open". Bug #75110 - " Massive, to-be-compressed not committed InnoDB table is total database downtime ". This problem was reported by Jouni Jrvinen back in 2014. Surely this is not a bug, but it seems nobody even tried to speed up compression in any way on multiple cores. Bug #84439 - " Table of row size of ~800 bytes does not compress with KEY_BLOCK_SIZE=1 ". It was reported by Jean-Francois Gagne , who asked for a reasonable error message at least. Nothing happens after verification. Bug #77089 - " Misleading innochecksum error for compressed tables with key_block_size=16 ". This problem was reported by Laurynas Biveinis more than three years ago, immediately verified and then got zero attention.
On InnoDB Data Compression in MySQL
The boats above do not use the space for mooring efficiently. They need better compression.

Transparent Page Compression for InnoDB tables was added later and looked promising. If you are lucky to use filesystem with sparse file and hole punching support and proper OS or kernel version, then you could expect notable saving of disk space with very few additional keystrokes (like COMPRESSION="zlib" ) when defining the table. Different compression libraries were supported. Moreover (see here ), only uncompressed pages are stored in memory in this case, and this improved the efficiency of buffer pool usage. Sounded promising originally, but there are still bugs to consider:

Bug #78277 - " InnoDB deadlock, thread stuck on kernel calls from transparent page compression ". This bug alone (reported by Mark Callaghan back in 2015) may be a reason to NOT use the feature in production, as soon as you hit it (chances are high). there are many interesting comments that there are environments where the feature works as fast as expected, but I think this summary is good enough for most users: "[19 Oct 2015 15:56] Mark Callaghan

...

Slow on XFS, slow on ext4, btrfs core team tells me it will be slow there. But we can celebrate that it isn't slow on NVMFS - closed source, not GA, can't even find out where to buy it, not aware of anyone running it."

The bug is still "Open". Bug #81145 - " Sparse file and punch hole compression not working on windows ". Not that I care about Windows that much, but still. The bug is "Verified" for 2 years. Bug #87723 - " mysqlbackup cannot work with mysql5.7 using innodb page-level compression " Now this is awesome! Oracle's own MySQL Enterprise Backup does NOT support the feature. Clearly they cared about making it useful...
As a side note, same problem affects Percona's xtrabackup (see PXB-1394 ). MariaDB resolved the problem (and several related ones like MDEV-13023 ) with mariabackup tool. Bug #87603 - " compression/tablespace ignored in create/alter table when not using InnoDB ". COMPRESSION='.../' option is supported for MyISAM tables as well, and this again leads to problems when switching to another storage engine, as Tomislav Plavcic noted. Bug #78672 - " assert fails in fil_io during linkbench with transparent innodb compression ". This crash (assertion failure) was noted by Mark Callaghan back in 2015. May not crash anymore s

          InnoDB Progress Information      Cache   Translate Page   Web Page Cache   
Tweet MySQL has since version 5.7 had support for progress information for some queries. As promised in my previous post, I will here discuss how you can use that to get progress information for ALTER TABLE on InnoDB tables. Background and Setup Progress information is implemented through the Performance Schema using the stage events. In version 8.0.12 there are currently seven stages that can provide this information for  ALTER TABLE statements on InnoDB tables. In MySQL 8, it is easy to list the stages capable of reporting progress information by using the setup_instruments Performance Schema table: mysql> SELECT NAME, ENABLED, TIMED FROM performance_schema.setup_instruments WHERE NAME LIKE 'stage/innodb/alter table%' AND PROPERTIES = 'progress'; +------------------------------------------------------+---------+-------+ | NAME | ENABLED | TIMED | +------------------------------------------------------+---------+-------+ | stage/innodb/alter table (end) | YES | YES | | stage/innodb/alter table (flush) | YES | YES | | stage/innodb/alter table (insert) | YES | YES | | stage/innodb/alter table (log apply index) | YES | YES | | stage/innodb/alter table (log apply table) | YES | YES | | stage/innodb/alter table (merge sort) | YES | YES | | stage/innodb/alter table (read PK and internal sort) | YES | YES | +------------------------------------------------------+---------+-------+ 7 rows in set (0.00 sec) This also shows how the setup_instruments table in MySQL 8 has some additional information about the instruments such as properties and documentation (not included in the output). Adding this information is still work in progress. MySQL 5.7 does not provide as easy a way to obtain the instruments providing progress information. Instead you need to consult the reference manual. However, the principle in using the feature is the same. As you can see, all of the instruments are enabled and timed by default. What is not enabled by default, however, is the consumer that can make the information available: mysql> SELECT NAME, ENABLED, sys.ps_is_consumer_enabled(NAME) AS EnabledWithHierarchy FROM performance_schema.setup_consumers WHERE NAME = 'events_stages_current'; +-----------------------+---------+----------------------+ | NAME | ENABLED | EnabledWithHierarchy | +-----------------------+---------+----------------------+ | events_stages_current | NO | NO | +-----------------------+---------+----------------------+ 1 row in set (0.01 sec) Since the consumers form a hierarchical system, the sys schema function ps_is_consumer_enabled() is used to show whether the consumer is enabled taking the whole hierarchy into consideration. In order to use the progress information, you need to enable the events_stages_current consumer. This is the consumer that is responsible for keeping the performance_schema.events_stages_current table up to date, i.e. record the current (or latest if there is no current stage) for each thread. With the default Performance Schema settings, the rest of the hierarchy is enabled. To enable event_stages_current and verify it will be consuming instruments, you can use the following queries: mysql> UPDATE performance_schema.setup_consumers SET ENABLED = 'YES' WHERE NAME = 'events_stages_current'; Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> SELECT NAME, ENABLED, sys.ps_is_consumer_enabled(NAME) AS EnabledWithHierarchy FROM performance_schema.setup_consumers WHERE NAME = 'events_stages_current'; +-----------------------+---------+----------------------+ | NAME | ENABLED | EnabledWithHierarchy | +-----------------------+---------+----------------------+ | events_stages_current | YES | YES | +-----------------------+---------+----------------------+ 1 row in set (0.00 sec) That is it. Now you can monitor the progress of the queries that uses the stages with progress information. Note: The more parts of the Performance Schema that is enabled and the more fine grained monitoring, the more overhead. Stages are not the worst with respect to overhead; nevertheless it is recommended you keep an eye on the affect of enabling the events_stages_current consumer. Monitoring Progress The base for monitoring the progress information is the performance_schema.events_stages_current table. There are two columns of interest for this discussion: WORK_COMPLETED: The amount of work that is reported to have been completed. WORK_ESTIMATED: The estimated amount of work that needs to be done. For InnoDB ALTER TABLE the estimated amount of work is for the entire operation. That said, the estimate may be revised during the process, so it may happen that the if you calculate the percentage it decreases as time goes. However, in general the percentage (100% * WORK_COMPLETED/WORK_ESTIMATED) will increase steadily until the operation completes at 100%. To learn more about how the progress information works, the following pages in the manual are recommended: Stage Event Progress Information Monitoring ALTER TABLE Progress for InnoDB Tables Using Performance Schema For now, let’s look at an example. Example For the example, the salaries table in the employees sample database will be used. The table is sufficiently large that it will be possible to query the progress while adding a column using the INPLACE algorithm. As discussed in MySQL 8.0.12: Instant ALTER TABLE, it is possible to add a column instantly, but for the purpose of this example, the INPLACE algorithm illustrates the progress information feature better. The query that will be executed is: ALTER TABLE salaries ADD COLUMN new_col int NOT NULL DEFAULT 0, ALGORITHM=INPLACE; The performance_schema.events_stages_current table can be joined with the performance_schema.events_statements_current to show the query and progress. For example: mysql> SELECT stmt.THREAD_ID, stmt.SQL_TEXT, stage.EVENT_NAME AS State, stage.WORK_COMPLETED, stage.WORK_ESTIMATED, ROUND(100*stage.WORK_COMPLETED/stage.WORK_ESTIMATED, 2) AS CompletedPct FROM performance_schema.events_statements_current stmt INNER JOIN performance_schema.events_stages_current stage ON stage.THREAD_ID = stmt.THREAD_ID AND stage.NESTING_EVENT_ID = stmt.EVENT_ID\G *************************** 1. row *************************** THREAD_ID: 63857 SQL_TEXT: ALTER TABLE salaries ADD COLUMN new_col int NOT NULL DEFAULT 0, ALGORITHM=INPLACE State: stage/innodb/alter table (read PK and internal sort) WORK_COMPLETED: 8906 WORK_ESTIMATED: 27351 CompletedPct: 32.56 1 row in set (0.00 sec) There is another way though. Instead of using the performance_schema.events_stages_current table directly, an easier way is to use the sys.session view. This is an advanced process list that includes much more information than the usual SHOW PROCESSLIST statement including progress information. The performance of sys.session has been improved with more than an order of magnitude in MySQL 8 by the addition of indexes to the Performance Schema tables making it highly useful. Querying the sys.session view for sessions showing progress information while the ALTER TABLE is in progress returns an output similar to the following example: mysql> SET @sys.statement_truncate_len = 85; Query OK, 0 rows affected (0.00 sec) mysql> SELECT thd_id, conn_id, db, command, state, current_statement, statement_latency, progress, current_memory, program_name FROM sys.session WHERE progress IS NOT NULL\G *************************** 1. row *************************** thd_id: 63857 conn_id: 63818 db: employees command: Query state: alter table (merge sort) current_statement: ALTER TABLE salaries ADD COLUMN new_col int NOT NULL DEFAULT 0, ALGORITHM=INPLACE statement_latency: 4.22 s progress: 49.39 current_memory: 464.27 KiB program_name: MySQLWorkbench 1 row in set (0.06 sec) In the example, the @sys.statement_truncate_len user variable is set to 85. By default the sys schema ensures the current statement is at most 64 characters long. In order to avoid truncation in this case, the truncate length is increased to 85. The example output shows that the progress is at around 49%. It is important to note that is an estimate and not an exact number. The ALTER TABLE is performing a merge sort at the time, and the query has been running for 4.22 seconds. A couple of other interesting columns are included. It can be seen the connection is using 464KiB at the time. In MySQL 8 memory instrumentation is enabled by default (in MySQL 5.7 you need to enable it yourself). Additionally, the name of the program executing the query is MySQLWorkbench, that is the query originates from MySQL Workbench. So, next time you plan a large ALTER TABLE operation, consider enabling the events_stages_current consumer, so you can follow the progress. Tweet

          How to Install PHP on Windows      Cache   Translate Page   Web Page Cache   

We've previously shown you how to get a working local installation of Apache on your Windows PC. In this article, we'll show how to install PHP 5 as an Apache 2.2 module.

Why PHP?

PHP remains the most widespread and popular server-side programming language on the web. It is installed by most web hosts, has a simple learning curve, close ties with the MySQL database, and an excellent collection of libraries to cut your development time. PHP may not be perfect, but it should certainly be considered for your next web application. Both Yahoo and Facebook use it with great success.

Why Install PHP Locally?

Installing PHP on your development PC allows you to safely create and test a web application without affecting the data or systems on your live website. This article describes PHP installation as a module within the Windows version of Apache 2.2. Mac and Linux users will probably have it installed already.

All-in-One packages

There are some excellent all-in-one Windows distributions that contain Apache, PHP, MySQL and other applications in a single installation file, e.g. XAMPP (including a Mac version), WampServer and Web.Developer. There is nothing wrong with using these packages, although manually installing Apache and PHP will help you learn more about the system and its configuration options.

The PHP Installer

Although an installer is available from php.net, I would recommend the manual installation if you already have a web server configured and running.

The post How to Install PHP on Windows appeared first on SitePoint.

Thanks for your answer.
I’ve tried your query by phpmyadmin and the answer has been:

“ #1146 – Table ‘Sql229117_1.textpattern’ doesn’t exist”

Afterwards I’ve posted the same expression inside the table ‘_1textpattern’.
There was already this expression:
SELECT * FROM `_1textpattern` WHERE 1

So I’ve posted bellow it; then I ‘ve pushed the btton

and the answer was: “#1064 – You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘UPDATE textpattern SET url_title = TRIM’ at line 2”.

          More automated control in MySQL Cluster 7.6.7      Cache   Translate Page   Web Page Cache   

Apart from bug fixes the 7.6.7 version of mysql Cluster also brings

a major improvement of restart times through adaptively controlling

checkpoint speed.

Many DBMSs work hard on automating management of the database nodes.

In NDB automated management was a design point from the very first

version. This means that nodes crash and restart without operator

assistance.

For the last years we have also worked on developing algorithms that

require less configuration. This will greatly simplify the configuration

of NDB Cluster.

In 7.6.7 we have made it much easier to configure handling of checkpoints

(LCPs) and REDO logging.

In earlier versions of NDB the checkpoint speed has been controlled by

two things. The first is based on the following configuration variables:

MinDiskWriteSpeed: This is the minimum disk write speed we will attempt

to write during a checkpoint even in the presence of CPU overload and

disk overload. This defaults to 10 MByte per second, this is the sum

on all LDM threads, thus on the entire data node.

MaxDiskWriteSpeed: This is the maximum disk write speed we will attempt

to write during a checkpoint, if no CPU overload or disk overload is

seen, this is the checkpoint speed that will be used in normal operation.

Defaults to 20 MByte per second.

MaxDiskWriteSpeedOtherNodeRestart: This is the maximum disk write speed

we will write during a checkpoint when another node is restarting. It

defaults to 50 MByte per second.

MaxDiskWriteSpeedOwnNodeRestart: This is the maximum disk write speed

we will write during a checkpoint when our node is restarting. It defaults to

200 MByte per second.

The actual disk write speed achieved is using those configuration variables

in combination with an adaptive algorithm that will decrease the checkpoint

speed when the CPU or the disk is overloaded.

These parameters exists also in 7.6.7, but there is very little reason to

change them from their default value if the new configuration variable

EnableRedoControl is set to 1. By default this variable is set to 0 to

avoid changes of behaviour in a GA released version of MySQL Cluster.

In earlier versions of NDB it was necessary to have very large REDO logs.

The reason is that earlier versions (7.5 and earlier) wrote the entire

database to disk in each checkpoint. This meant that checkpoints during

massive inserts got larger and larger and to ensure successful insertion

of the entire data set it was necessary to have REDO logs that was about

twice the size of the DataMemory.

Now in 7.6.7 it should be quite enough to have 2-4 GByte of REDO log per

REDO log part (normally equal to the number of LDM threads). This REDO

log size works perfectly even when loading TBytes of data into NDB.

Remember that EnableRedoControl needs to be set to 1 for this to work.

Thus in MySQL Cluster 7.6.7 one can simplify the configuration of REDO logs

and checkpointing.

In earlier versions we need to set the following variables:

NoOfFragmentLogParts (always set equal to number of LDM threads)

NoOfFragmentLogFiles

FragmentLogFileSize

MinDiskWriteSpeed

MaxDiskWriteSpeed

MaxDiskWriteSpeedOtherNodeRestart

MaxDiskWriteSpeedOwnNodeRestart

The product of NoOfFragmentLogParts, NoOfFragmentLogFiles and

FragmentLogFileSize is the size of the REDO log. In earlier versions

this product should be roughly two times the setting of DataMemory.

The default setting of FragmentLogFileSize is 16 MByte. Personally I always

increase this setting to 256 MByte (set to 256M).

So e.g. with a DataMemory of 100 GByte and 8 LDM threads one can set those to

NoOfFragmentLogParts=8

NoOfFragmentLogFiles=50

FragmentLogFileSize=256M

This gives a REDO log size of 200 GByte.

The setting of disk write speed will be discussed a bit more in a coming blog.

In 7.6.7 one can instead configure as follows.

EnableRedoControl=1

NoOfFragmentLogParts=8

NoOfFragmentLogFiles=8

FragmentLogFileSize=256M

The setting of disk write speed variables need not be considered. The setting

of NoOfFragmentLogFiles to 8 and FragmentLogFileSize to 256M should work for

almost all setups of NDB. Only when dealing with data nodes larger than

one terabyte could it be considered to increase the REDO log size. The

NoOfFragmentLogParts should still be set to the number of LDM threads.

Thus in 7.6.7 a lot less thought has to go into configuration of REDO logs

and disk write speeds. Disk write speed still affects backup write speeds

as well though, so it could be a good idea to consider how fast you want to

write your backups using the variables MinDiskWriteSpeed and MaxDiskWriteSpeed.

The reason that disk write speeds for checkpoints is less important to consider

is that we calculate how fast we need to write the checkpoints based on the

write activity in NDB. This means that when setting EnableRedoControl the write

speed to the disk can be quite substantial. So this setting will not work very

well unless the disk subsystem is able to handle the load. The disk subsystem

should be able to handle around 100 MByte of disk writes per LDM thread.

With modern HW this should not be an issue, in particular not when using NVMe

drives. In our benchmarking we are using a RAID 0 setup of 6 SSD drives. With

8 LDM threads inserting at full speed we use about 50% of the disk bandwidth

in this case (500 MByte per second).


          Monitoring NDBCluster Copying Alter Progress      Cache   Translate Page   Web Page Cache   

mysql NDB Cluster has great support for online (inplace) schema changes, but it is still sometimes necessary to perform an offline (copying) ALTER TABLE . These are relatively expensive to make as the entire table is copied into a new table which eventually replace the old table.

One example where a copying ALTER TABLE is required is when upgrading from MySQL NDB Cluster 7.2 or earlier to MySQL NDB Cluster 7.3 or later. The format used for temporal columns changed between these version (corresponding to MySQL Server 5.5 to 5.6). In order to take advantage of the new temporal format, a table rebuild is required.


Monitoring NDBCluster Copying Alter Progress

Note:Support for the old temporal format has been removed in MySQL 8.0. So, you must upgrade your tables before an upgrade is possible. There is at the time of writing no MySQL NDB Cluster releases based on MySQL Server 8.0.


Monitoring NDBCluster Copying Alter Progress
Schematic representation of a copying ALTER TABLE

For long running operations, it can be useful to monitor the progress. There is no built-in way to do this like there is for InnoDB in MySQL 5.7 and later (I promise, I will soon write a blog about that), however the ndbinfo schema can give some information about the progress.

The ndbinfo schema is a virtual schema with views that show information from the data nodes. You can argue it is MySQL NDB Cluster’s answer to the Performance Schema. The ndbinfo schema was introduced in MySQL NDB Cluster 7.1 more than eight years ago and has steadily seen more and more information becoming available.

One of these changes arrived in MySQL NDB Cluster 7.4 where the memory_per_fragment views was added. This view shows detailed information about the memory used per fragment (in most cases the same as partitions). This can also be used to get an estimate of the progress of a copying ALTER TABLE .

As mentioned, a copying ALTER TABLE is similar to creating a new table with the new schema (which may potential be the same as the old schema), then inserting all of the data from the old table to the new. At the end, the two tables are swapped and the old table dropped.


Monitoring NDBCluster Copying Alter Progress

Note: Remember that a copying ALTER TABLE is an offline operation. Any changes made to the table during the operation may be lost! Make sure the table is read-only while the ALTER TABLE is executing.

The temporary table (that later become the real table) is an NDBCluster table like other user created tables. This means the table will show up in ndbinfo.memory_per_fragment as a normal table, just with a special table name.

Temporary tables are named like #sql-7f4b_4 where the part after the is generated based on the operating system process ID of the mysqld process and the connection id of the connection executing the ALTER TABLE . The schema name for the temporary table is the same as for the original table. In the example the process ID is 32587 or 7f4b in hexadecimal notation and the connection ID is 4.

As an example consider a rebuild of the db1.t1 table. In this case the fully qualified name (the name used by NDB Cluster instead of the normal table name) is db1/def/t1 , i.e. the schema name and table name with /def/ between them. You can choose to create the fully qualified name for the temporary table as described above. An alternative, if you just have one concurrent table rebuild in the schema is to just look for the fully qualified name matching db1/def/#sql-% .

So, you can use the ndbinfo.memory_per_fragment table to see how much memory is allocated per fragment of the temporary table compared to the original table. For example:

mysql> SELECT fq_name, parent_fq_name, type, table_id, (fixed_elem_alloc_bytes-fixed_elem_free_bytes) AS FixedBytes, (var_elem_alloc_bytes-var_elem_free_bytes) AS VarBytes, hash_index_alloc_bytes FROM ndbinfo.memory_per_fragment WHERE fq_name = 'db1/def/t1' OR fq_name LIKE 'db1/def/#sql-%' OR parent_fq_name = 'db1/def/t1' OR parent_fq_name LIKE 'db1/def/#sql-%'; +------------------------+---------------------+-------------------+----------+------------+----------+------------------------+ | fq_name| parent_fq_name| type| table_id | FixedBytes | VarBytes | hash_index_alloc_bytes | +------------------------+---------------------+-------------------+----------+------------+----------+------------------------+ | db1/def/NDB$BLOB_45_3| db1/def/t1| User table| 46 | 100580 |1038088 |40960 | | db1/def/NDB$BLOB_45_3| db1/def/t1| User table| 46 |99320 |1056380 |40960 | | db1/def/NDB$BLOB_45_3| db1/def/t1| User table| 46 | 100580 |1038088 |40960 | | db1/def/NDB$BLOB_45_3| db1/def/t1| User table| 46 |99320 |1056380 |40960 | | sys/def/45/val1$unique | db1/def/t1| Unique hash index | 49 |77640 |0 |40960 | | sys/def/45/val1$unique | db1/def/t1| Unique hash index | 49 |76184 |0 |40960 | | sys/def/45/val1$unique | db1/def/t1| Unique hash index | 49 |77640 |0 |40960 | | sys/def/45/val1$unique | db1/def/t1| Unique hash index | 49 |76184 |0 |40960 | | sys/def/45/val1| db1/def/t1| Ordered index | 48 |39424 |0 |0 | | sys/def/45/val1| db1/def/t1| Ordered index | 48 |37792 |0 |0 | | sys/def/45/val1| db1/def/t1| Ordered index | 48 |39424 |0 |0 | | sys/def/45/val1| db1/def/t1| Ordered index | 48 |37792 |0 |0 | | sys/def/45/PRIMARY | db1/def/t1| Ordered index | 47 |39424 |0 |0 | | sys/def/45/PRIMARY | db1/def/t1| Ordered index | 47 |37792 |0 |0 | | sys/def/45/PRIMARY | db1/def/t1| Ordered index | 47 |39424 |0 |0 | | sys/def/45/PRIMARY | db1/def/t1| Ordered index | 47 |37792 |0 |0 | | db1/def/NDB$BLOB_14_3| db1/def/#sql-7f4b_4 | User table| 15 |43180 | 446148 |24576 | | db1/def/NDB$BLOB_14_3| db1/def/#sql-7f4b_4 | User table| 15 |44404 | 471920 |24576 | | db1/def/NDB$BLOB_14_3| db1/def/#sql-7f4b_4 | User table| 15 |43360 | 450184 |24576 | | db1/def/NDB$BLOB_14_3| db1/def/#sql-7f4b_4 | User table| 15 |44404 | 471920 |24576 | | sys/def/14/val1$unique | db1/def/#sql-7f4b_4 | Unique hash index | 44 |33448 |0 |24576 | | sys/def/14/val1$unique | db1/def/#sql-7f4b_4 | Unique hash index | 44 |34176 |0 |24576 | | sys/def/14/val1$unique | db1/def/#sql-7f4b_4 | Unique hash index | 44 |
          A loosing battle with a DEFAULT column value… Lessons learned.      Cache   Translate Page   Web Page Cache   

While learning through a video tutorial on creating Form and Login Systems with php and mysql, I ran into a minor issue, that I would like to share in this blog post and what I did to solve it.

A loosing battle with a DEFAULT column value… Lessons learned.

Photo by H E N G S T R E A M on Unsplash

To start, I have this table and structure:

mysql> desc users; +------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | first_name | varchar(25) | NO | | NULL | | | last_name | varchar(25) | NO | | NULL | | | email | varchar(100) | NO | | NULL | | | password | text | NO | | NULL | | | image | text | YES | | NULL | | +------------+--------------+------+-----+---------+----------------+ 6 rows in set (0.00 sec)

I needed to add in a column for what date a user registers or joins in the ‘system’.

Simple enough.

Use ALTER TABLE ADD COLUMN syntax.

In my opinion, this a prime use case for a DEFAULT column value.

Why not make it as easy as possible for the user registering (Not to mention yourself the programmer!) and just remove all the ‘guesswork’, such as:

What is even the date today (when registering) anyway? (Doh.. *Facepalm*) What format is the user to enter? (e.g., “July 2nd, 2018”, 07/02/18, 02 Jul 2018, etc…) You get the picture. That’s another field in the form on the front-end to code and manage.

So, my thinking is when a user registers, they register and I’ll just store the current date for them.

Easy peasy.

They (the user), need not even see the date field.

Matter of fact, MySQL has some handy date and time functions already.

(Check out Handy MySQL Date Functions With Examples I wrote about a few of them.)

In particular, 2 synonymous functions CURDATE() and CURRENT_DATE() both return, wait for it…. the current date.

Perfect…

Let me get this ‘light work’ done and get back to more pressing things (I think to myself).

So I’ll add in a column, date_registered , of data type DATE right after the existing image column.

Give it a default of CURDATE() , and on INSERT (registering), one less thing I need to worry with right?

Here is the SQL below (and there is plenty of it too):

mysql> alter table users add column date_registered date after image default curdate(); ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'default curdate()' at line 1 mysql> alter table users add column date_registered date default curdate() after image; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'curdate() after image' at line 1 mysql> alter table users add column date_registered date default curdate() after image; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'curdate() after image' at line 1 mysql> alter table users add column date_registered date set default curdate() after image; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'set default curdate() after image' at line 1 mysql> alter table users add column date_registered date after image set default curdate(); ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'set default curdate()' at line 1 mysql> alter table users add column date_registered date after image set default curdate; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'set default curdate' at line 1 mysql> alter table users add column date_registered date default curdate() after image; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'curdate() after image' at line 1 mysql> alter table users add date_registered date default curdate() after image; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'curdate() after image' at line 1 mysql> alter table users add column date_registered date after image set default curdate(); ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'set default curdate()' at line 1

Are you laughing at me yet?

I am.

I tried every configuration of the command that I knew how to get this column added with a DEFAULT value and in a certain position within the table.

Screw the DEFAULT value for now, can I please just get the column added already?

mysql> alter table users add column date_registered date after image; Query OK, 0 rows affected (0.90 sec) Records: 0 Duplicates: 0 Warnings: 0

Finally…

Seems like you can’t complete both of those actions in the same command I came to conclude.

You know adding in a new column to an existing table and being picky enough to want a DEFAULT value as well for crying out loud.

Now that the column is there, I’ll add in the DEFAULT and get back to PHP.

mysql> alter table users alter column date_registered set default curdate(); ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'curdate()' at line 1 mysql> alter table users alter column date_registered set default

准备知识:mysql事务

1 基本操作 sql.Tx

tx会从连接池中取一个空闲的连接,直至调用 commit 或者 rollback 才会释放

tx, err := db.Begin() // 创建tx对象 tx.Query(command1) tx.Exec(command2) tx.Commit() 2 并发

事务只有 一个连接 ,事务内的操作是 串行 的

db, _ := sql.Open(...) rows, _ := db.Query("SELECT id FROM tt_users") for rows.Next(){ var ( user_id int openid string ) rows.Scan(&user_id) db.QueryRow("SELECT openid FROM tt_users_third WHERE user_id = ?", user_id).Scan(&openid) }

这段代码在并发执行的时候 Query 和 QueryRow 是独立的两个连接。非 tx 对象的操作,每执行一个操作之前会从连接池取空闲连接。

rows, _ := tx.Query("SELECT id FROM tt_users") for rows.Next(){ var ( user_id int openid string ) rows.Scan(&user_id) tx.QueryRow("SELECT openid FROM tt_users_third WHERE user_id = ?", user_id).Scan(&openid) }

tx执行完 Query 方法之后,连接转移到 rows 上,在 Next 方法中, tx.QueryRow 将尝试获取该连接进行操作。因为还没有调用 rows.Close() ,因此连接还处于 busy 状态, tx 无法进行 QueryRow 操作。这时候使用 JOIN 语句可以规避这个问题。

3 实践

事务处理过程中出现了异常为保证数据完整一致性和及时释放连接,需要 rollback 。

tx, err := db.Begin() if err != nil { log.Println(err) } var ( user_id uint openid string ) err = tx.QueryRow("SELECT user_id FROM tt_users WHERE phone = ?", phone).Scan(&user_id) if err != nil { err = tx.Rollback() if err != nil { log.Println("tx.Rollback() Error:" + err.Error()) return } } err = tx.QueryRow("SELECT openid FROM tt_user_third WHERE user_id = ?", user_id).Scan(&openid) if err != nil { err = tx.Rollback() if err != nil { log.Println("tx.Rollback() Error:" + err.Error()) return } } err := tx.Commit() if err != nil { err = tx.Rollback() if err != nil { log.Println("tx.Rollback() Error:" + err.Error()) return } }

mysqldump 是用于转存储 mysql 数据库的实用程序。

主要产生一个 SQL 脚本,其中包含从头重新创建数据库的所有命令。

导出脚本过程大概如下:创建数据库判断语句、删除表、创建表、锁表、禁用索引、插入数据、启用索引、解锁表。

快速使用 # game 是库名 # 完整导出一个库 # 包括建库语句、表结构、数据 mysqldump -uroot -proot --host=127.0.0.1 --port=3306 --databases game > test.sql # 只导出表结构 mysqldump -uroot -proot --host=127.0.0.1 --port=3306 -d game > test.sql # 只导出数据 mysqldump -uroot -proot --host=127.0.0.1 --port=3306 -t game > test.sql # 导出一个数据库中多个表的数据和结构 mysqldump -uroot -proot --host=127.0.0.1 game --tables articles users > test.sql mysqldump -uroot -proot --host=127.0.0.1 game articles users > test.sql # 恢复导出数据 mysql -u username -proot databse < backup.sql 复制代码 参数 --user=user_name, -u user_name

连接数据库的用户名。

--password=password, -p[password]

连接数据库的密码,如果使用 -p 缩写,和密码之间不能有空格。

--opt or --compact 使用 --opt 等于使用这些参数 --add-drop-table, --add-locks, --create-options, --disable-keys, --extended-insert, --lock-tables, --quick, and --set-charset ,默认情况下即使不加 --opt 参数也是开启的。 使用 --compact 等于使用这些参数 --skip-add-drop-table, --skip-add-locks, --skip-comments, --skip-disable-keys, and --skip-set-charset ,默认不开启。 --databases, -B

指定导出的库名。

--all-databases

表示导出所有的库。

--tables

会覆盖 --databases or -B 选项,指定导出某个表就会忽略库选项。

--no-data, -d

不导出数据,只导出表结构。

Do not dump table contents

--no-create-info, -t

只导出数据,不导出表结构,不添加 CREATE TABLE 语句。

--no-create-db, -n

不添加 CREATE DATABASE 建库语句。

Replicating from MySQL 8.0 to MySQL 5.7

In this blog post, we’ll discuss how to set a replication from mysql 8.0 to MySQL 5.7. There are some situations that having this configuration might help. For example, in the case of a MySQL upgrade, it can be useful to havea master that is using a newer version of MySQL to an older version slave as a rollback plan. Another example is in the case of upgrading a master x master replication topology.

Officially, replication is only supported between consecutive majorMySQLversions, and only from a lower version master to a higher version slave. Here is an example of a supported scenario:

5.7 master > 8.0 slave

while the opposite is not supported:

8.0 master > 5.7 slave

In this blog post, I’ll walk through how to overcome the initial problems to set a replication working in this scenario. I’ll alsoshow some errors that can halt the replication if a new feature from MySQL 8 is used.

Here is the initial set up that will be used to build the topology:

slave > select @@version; +---------------+ | @@version | +---------------+ | 5.7.17-log | +---------------+ 1 row in set (0.00 sec) master > select @@version; +-----------+ | @@version | +-----------+ | 8.0.12 | +-----------+ 1 row in set (0.00 sec)

First, before executing the CHANGE MASTER command, you need to modify the collation on the master server. Otherwise the replication will run into this error:

slave > show slave status\G Last_Errno: 22 Last_Error: Error 'Character set '#255' is not a compiled character set and is not specified in the '/opt/percona_server/5.7.17/share/charsets/Index.xml' file' on query. Default database: 'mysql8_1'. Query: 'create database mysql8_1'

This is because the default character_set and the collation has changed on MySQL 8. According to the documentation :

The default value of the character_set_server and character_set_database system variables has changed from latin1 to utf8mb4 .

The default value of the collation_server and collation_database system variables has changed from latin1_swedish_ci to utf8mb4_0900_ai_ci .

Let’s change the collation and the character set to utf8 on MySQL 8 (it is possible to use any option that exists in both versions):

# master my.cnf [client] default-character-set=utf8 [mysqld] character-set-server=utf8 collation-server=utf8_unicode_ci

You need to restart MySQL 8 to apply the changes. Next, after the restart, you have to create a replication user using mysql_native_password .This is because MySQL 8 changed the defaultAuthentication Plugin to caching_sha2_password which is not supported by MySQL 5.7. If you try to execute the CHANGE MASTER command with a user using caching_sha2_password plugin, you will receive the error message below:

Last_IO_Errno: 2059 Last_IO_Error: error connecting to master 'root@127.0.0.1:19025' - retry-time: 60 retries: 1

To create a user using mysql_native_password :

master> CREATE USER 'replica_user'@'%' IDENTIFIED WITH mysql_native_password BY 'repli$cat'; master> GRANT REPLICATION SLAVE ON *.* TO 'replica_user'@'%';

Finally, we can proceed as usual to build the replication:

master > show master status\G *************************** 1. row *************************** File: mysql-bin.000007 Position: 155 Binlog_Do_DB: Binlog_Ignore_DB: Executed_Gtid_Set: 1 row in set (0.00 sec) slave > CHANGE MASTER TO MASTER_HOST='127.0.0.1', MASTER_USER='replica_user', MASTER_PASSWORD='repli$cat',MASTER_PORT=19025, MASTER_LOG_FILE='mysql-bin.000007', MASTER_LOG_POS=155; start slave; Query OK, 0 rows affected, 2 warnings (0.01 sec) Query OK, 0 rows affected (0.00 sec) # This procedure works with GTIDs too slave > CHANGE MASTER TO MASTER_HOST='127.0.0.1', MASTER_USER='replica_user', MASTER_PASSWORD='repli$cat',MASTER_PORT=19025,MASTER_AUTO_POSITION = 1 ; start slave;

Checking the replication status:

master > show slave status\G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 127.0.0.1 Master_User: replica_user Master_Port: 19025 Connect_Retry: 60 Master_Log_File: mysql-bin.000007 Read_Master_Log_Pos: 155 Relay_Log_File: mysql-relay.000002 Relay_Log_Pos: 321 Relay_Master_Log_File: mysql-bin.000007 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 155 Relay_Log_Space: 524 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 100 Master_UUID: 00019025-1111-1111-1111-111111111111 Master_Info_File: /home/vinicius.grippa/sandboxes/rsandbox_5_7_17/master/data/master.info SQL_Delay: 0 SQL_Remaining_Delay: NULL Slave_SQL_Running_State: Slave has read all relay log; waiting for more updates Master_Retry_Count: 86400 Master_Bind: Last_IO_Error_Timestamp: Last_SQL_Error_Timestamp: Master_SSL_Crl: Master_SSL_Crlpath: Retrieved_Gtid_Set: Executed_Gtid_Set: Auto_Position: 0 Replicate_Rewrite_DB: Channel_Name: Master_TLS_Version: 1 row in set (0.01 sec)

Executing a quick test to check if the replication is working:

          有效升级 MySQL 表的 ip 字段      Cache   Translate Page   Web Page Cache   

在文章IPv6 使用及注意事项 中我们提到了应用程序如果要支持 IPv6, 需要关注相关数据库的修改, 不过由于业务设计的不同, 有些程序可能使用 char , varchar 等存储 ip 字符串, 有些程序也可能考虑到索引效率使用 int unsigned 存储 ip 的整形. 不过对于 IPv6 地址, 由于其 128 bit 的长度, 决定了 IP 地址数量为 (2^128 1), 这个值对 64 位的主机而言无法存储, 所以建议使用 varchar 类型存储所有的 IPv6 地址. 下文则主要介绍修改表时需要注意的一些操作事项.

原先用 char 或 varchar 类型存储 ip 信息的表

有效的 IPv6 地址的长度大概为 3 ~ 39, 所以要使字段能够存储 IPv6 地址, 需要修改字段长度为 varchar(39) :

::1 ~ 2001:0db8:1111:1111:1111:1111:1111:1111 原先用 int 类型存储 ip 信息的表

有以下两种方式进行操作, 不过都需要程序端做相关的配合才能做到无缝升级而不影响业务的访问, 两种方式都需要pt-osc 工具进行在线修改表操作.

直接修改 int 为 varchar(39)

如下所示, o 为原表中旧的 ipv4 数据, d 为 pt-osc 修改过程中程序插入的数据, n 为 pt-osc 开始操作后程序新插入的数据.

convert int ---------> varchar o => 168562985 '10.12.17.41' o => 168562971 '10.12.17.27' o => 2886729730 '172.16.0.2' =================================================== applications(handle data depend on ip column type) =================================================== befre pt-osc d => 2886736139 ==> ? d => 3232235778 ==> ? =================================================== after pt-osc =================================================== applications(all data as varchar) n => 3401909527 ==> ?

如果只是单纯的修改 int 为 varchar 类型, 需要进行以下步骤:

1. 使用 pt-osc 开始修改表的过程中, 原有的 int 数据如何转换为有效的 ip 字符串格式?

需要单修改 pt-osc 工具, 将旧的 int 值转为 varchar 类型.

2. 应用程序端需要根据列的类型区别处理更新和查询操作;

3. 使用 pt-osc 开始修改表的过程中, 程序新插入的数据如何转成有效的 ip 格式, 程序如何读取 ip 列相关的信息?

在 pt-osc 修改表的过程中, 对原表的更新和读取操作保持不变, 但需要单独修改 pt-osc 的触发器以修改新表的字段类型;

4. 使用 pt-osc 修改完表结构后, 新的 ip 信息使用什么格式存储?

在 pt-osc 修改完表结构之后需要及时修改程序端以插入 varchar 格式的 ip 信息, 以避免 select 查询等操作的类型转换引起性能骤降的问题. 同时也要单独处理程序修改过程中产生的 int 类型的数据;

5. 修改应用程序, 所有 ip 列数据都以 varchar 格式处理;

如果没有第 2 步操作, 则第 4 个问题将决定无法无缝升级整个业务, 因为ip 列相关查询需要类型转换, 这部分业务容易出现连接吃满, 响应缓慢的问题. 第 1, 3 步 pt-osc 补丁见 pt-osc , 使用 --convert-column 和 --convert-funtion 选项进行操作, 如下所示:

pt-online-schema-change --alter 'modify column ip varchar(39)' A=utf8,h=127.0.0.1,u=root,D=percona,t=login_ip --ask-pass --convert-column ip --convert-function inet_ntoa --execute 额外增加 ipv6 列

如果单独增加列 varchar(39) , 则处理过程相对简单, 同样需要应用程序做相应的配合. 如下所示:

convert int ---------> ipv4(int), ipv6(varchar) o => 168562985 168562985, NULL o => 168562971 168562971, NULL o => 2886729730 2886729730, NULL =================================================================== applications(only handle ipv4) =================================================================== befre pt-osc d => 2886736139 ==> 2886736139, d => 3232235778 ==> 3232235778, =================================================================== after pt-osc =================================================================== applications(handle ipv4/ipv6) n => 3401909527 ==> 3401909527, NULL n => 2001:db8::1 ==> NULL, '2001:db8::1' 1. 使用 pt-osc 修改表的过程中, 原有的 int 类型不变, ipv6 字段为 NULL 值;

2. 修改应用程序, 仅处理 ipv4 相关的列. 如果程序以数组等方式获取相关信息, 需要修改为按列名获取信息, 以免修改列引起列不匹配问题.

很多程序使用下面的方式获取表中的数据, 这种方式关联了表中所有列的顺序, 额外给表增加列容易引起程序的查询和更新不匹配的问题:

string sql; array @result; sql = "select * from ... where ..."; @result = dbh->selectall_array(sql, parameters); print result[0], result[1], ....; sql = "insert into ... values (....)"; int status = dbh->do(sql, parameters); 3. 第 2 步修改完后, 使用 pt-osc 增加新列;

4. pt-osc 修改完表后, 修改程序同时处理 ipv4 和 ipv6 信息, 程序的查询和更新都需要做对应的修改.

如下所示, 同一行中仅有 ipv4 或 ipv6 有值:

CREATE TABLE `login_log` ( `id` int(10) NOT NULL AUTO_INCREMENT, `user_id` int(10) DEFAULT NULL, `create_time` datetime DEFAULT NULL, `login_ip` int(10) unsigned DEFAULT NULL, `login_ipv6` varchar(39) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 insert into login_log(user_id, create_time, login_ip, login_ipv6) values(1239, now(), inet_aton('192.168.10.2'), NULL); insert into login_log(user_id, create_time, login_ip, login_ipv6) values(1239, now(), NULL, lower('fe80::222:18ff:fe67:4fb1')); insert into login_log(user_id, create_time, login_ip, login_ipv6) values(1239, now(), NULL, NULL); select user_id, create_time, ifnull(inet_ntoa(login_ip), login_ipv6) as ip from login_log; +---------+---------------------+--------------------------+ | user_id | create_time | ip | +---------+---------------------+--------------------------+ | 1239 | 2018-07-24 10:03:28 | 192.168.10.2 | | 1239 | 2018-07-24 10:04:25 | fe80::222:18ff:fe67:4fb1 | | 1239 | 2018-07-24 10:05:38 | NULL | +---------+---------------------+--------------------------+

单独增加列需要程序做更多的额外配合, 不过同上面的一样可以无缝升级. 相比上面的方式, 无需承担修改 pt-osc 工具的风险, 不过程序端改的较多, 如果表有 ip 相关的索引, 也同样需要增加 ipv6 列的索引.

总结

整体上而言, 如果要达到无缝升级的目的, 原先为 char 或 varchar 类型的表反而更为方便, 直接使用 pt-osc 工具修改长度即可. 而原先为 int 类型的表则需要程序端做很多相应的配合, 两种方式各有利弊, 在修改的 pt-osc 无风险的情况下建议使用第 1 种方式修改表字段到 varchar 类型.


          这些有效的MySQL数据优化方法,你知道吗?      Cache   Translate Page   Web Page Cache   

数据库的增删改查的效率在开发中是十分重要的,好的数据库优化方法可以让你的数据库效率更高,今天小编来总结一些优化数据库的方法。

一:表优化

一般情况下表的数据越小,查询的速度也就越快:

1.垂直拆分表:把一个表中特别长的字段拆分成多张表,然后在查询时进行关联查询,这样可以有效的提高查询效率。

2.字段属性设置:长度类型设置够用就行,比如能设置成varchar(10)的就不要设置成varchar(100);对于某些只有固定几个值可选的字段,例如“性别”等,可以将它们定义为tinyint或int类型,因为在mysql中,数值型数据被处理起来的速度要比文本类型快。


这些有效的MySQL数据优化方法,你知道吗?
二:sql语句优化方法

1.索引可以加快查询速度但是有的操作却能破坏索引,比如:!=,<>操作符等会使索引失效。

2.尽量不要在 where 子句中使用 or 来连接条件,这样会破坏索引。

3.使用LIKE '%ABC'或LIKE '%ABC%'类型的查询也会破坏索引使索引失效,可以尝试使用全文搜索。

4.应尽量避免在 where 子句中对字段进行表达式操作或进行函数操作,这将导致引擎放弃使用索引而进行全表扫描

5.不要使用 select * from table ,用具体的字段列表代替“*”,不要返回用不到的任何字段。

6.避免频繁创建和删除临时表,以减少系统表资源的消耗。

7.尽量避免向客户端返回大数据量,若数据量过大,应该考虑相应需求是否合理。

8.尽量避免大事务操作,提高系统并发能力。


这些有效的MySQL数据优化方法,你知道吗?
三:用UNION来代替临时表

union查询,它可以把需要使用临时表的两条或更多的select查询合并的一个查询中。客户端的查询结束时,临时表会被自动删除,从而保证数据库整齐、高效。


这些有效的MySQL数据优化方法,你知道吗?
四:事务

虽然大部分的查询都可以使用:子查询(Sub-Queries)、连接(JOIN)和联合(UNION)来创建各种各样的查询,但不是所有的数据库操作都可以只用一条或少数几条SQL语句完成的。很多时候需要查询多张表,这是如果其中一条语句查询错误那么后面的执行对于需求来说将没有任何意义,这是就造成了不必要的操作,这是可以使用事务进行回滚,不去执行下面的错误语句。


          Store the system logs in MariaDB      Cache   Translate Page   Web Page Cache   

I’ve used Elasticsearch on OpenBSD to store my system logs for quite long now. And if it does the job, there are a few things I don’t like so much with it.

I only used a single instance so I was warned about availability. But a sudden power outage had severe impact on my daily data. Way much more than what I expected from a Production-ready software. Rebuilding and re-indexing the data was a real pain in the ass. From time to time, I also get errors about indexing that seem to go away without doing nothing.

The latter is probably due to my low memory server. But I want to store logs for only a couple of boxes. And I don’t want to reserve 4GB of RAM just for this. This “gimme more RAM” manner really annoys me. And as I also need RAM for Logstash (to parse the data and send them to Elasticsearch), this leads to way too much resources consumption.

That said, I decided to test another way for storing the logs : using a SGBD, namely MariaDB. I already have one running smooth. And I read Grafana was able to read data from it using SQL commands.

How it’ll work
Store the system logs in MariaDB

The stock syslogd(8) will be configured to send everything it gets to a local (or remote) syslog-ng daemon. The latter will parse, filter, format and store the logs into a (remote) mysql / MariaDB instance.

Prepare the SGBD

I’m usingmariadb-server-10.0.34v1 on OpenBSD 6.3/amd64.

First of all, I want to be able to compress the (text) data from the logs. So I had to enable a few InnoDB related options.

# vi /etc/my.cnf
(...)
innodb_file_per_table = 1
innodb_file_format = barracuda
innodb_strict_mode = 1
(...)
# rcctl restart mysqld

Then, I simply created a database and the credentials that’d be used by syslog-ng.

# mysql -u root -p
(...)
> CREATE database logsink;
> GRANT ALL PRIVILEGES ON logsink.* TO 'syslog-ng'@'%' IDENTIFIED BY 'changeme';
> FLUSH PRIVILEGES; Install and configure Syslog-NG

There are drivers required by syslog-ng to store data into mysql.

# pkg_add syslog-ng libdbi-drivers-mysql

Syslog-NG will listen on all interfaces, UDP and TCP ports. This way, any other box can send its logs to him.

# vi /etc/syslog-ng/syslog-ng.conf
(...)
source s_net {
udp(port(8514));
tcp(port(8514));
};
(...)
destination d_mysql_compressed {
sql(
type(mysql)
host("127.0.0.1") username("syslog-ng") password("changeme")
database("logsink")
table("_all")
create-statement-append(ROW_FORMAT=COMPRESSED)
columns(
"seq bigint(20) unsigned NOT NULL AUTO_INCREMENT PRIMARY KEY",
"unixtime bigint NOT NULL",
"facility varchar(16)",
"priority varchar(16)",
"level varchar(16)",
"host varchar(64) NOT NULL",
"program varchar(64) NOT NULL",
"pid smallint",
"message text",
"tag varchar(32)"
)
values(
"", "${UNIXTIME}", "$FACILITY_NUM", "$PRIORITY", "$LEVEL_NUM",
"${HOST}", "$PROGRAM", "${PID}", "${MSGONLY}", "$TAG"
)
indexes("unixtime", "host", "program", "tag")
null("")
);
};
(...)
log { source(s_net); filter(f_all); destination(d_mysql_compressed); };
(...)
# rcctl enable syslog_ng
# rcctl start syslog_ng

When this is done, configure syslogd(8).

# vi /etc/syslog.conf
(...)
*.* @127.0.0.1:8514
# rcctl restart syslogd Explore the logs

From here, the logs should be stored in MariaDB / MySQL.

A first look at the tables shows “COMPRESSED” is better than the standard storage ; regarding disk usage.

From the filesystem POV, the gain is also clearly visible.

Have a look at the most verbose programs is just a matter of writing SQL sentence:

+---------------------+----------+
| program | messages |

| rspamd | 12884 |
| doas | 4546 |
| collectd | 4265 |
| sshd | 3018 |
| cron | 2545 |
(...)

The logs can be accessed and rendered by Grafana. A simple query can print the last logs. Add alerting when some value appear and you have a nice event-based monitoring tool.

Organize storage

There are logs that I don’t want to store. And there are some that I want to store in a specific table. This can be done in Syslog-NG using filters.

filter f_all {
not program("fetchmail");
and not program("monit");
and not filter(f_unbound);
and not filter(f_apache);
};

This will not send messages from fetchmail or monit to the compressed table. Nor will it send messages that match the f_unbound and f_apache filters. Those two guys are used to store messages in a specific table with a dedicated schema. I’ll probably write about the details some day…

Now… send all your logs to Syslog-NG rather than Logstash. Count to 10 and get your RAM back! So far, MariaDB seem to handle it pretty well.

Peter Zaitsev: Basic Understanding of Bloat and VACUUM in PostgreSQL
Implementation of MVCC (Multi-Version Concurrency Control) in PostgreSQL is different and special when compared with other RDBMS. MVCC in PostgreSQL controls which tuples can be visible to transactions via versioning. What is versioning in PostgreSQL?

Let’s consider the case of an Oracle or a mysql Database. What happens when you perform a DELETE or an UPDATE of a row? You see an UNDO record maintained in a global UNDO Segment. This UNDO segment contains the past image of a row, to help database achieve consistency. (the “C” in A.C.I.D). For example, if there is an old transaction that depends on the row that got deleted, the row may still be visible to it because the past image is still maintained in the UNDO. If you are an Oracle DBA reading this blog post, you may quickly recollect the error ORA - 01555 snapshot too old . What this error means is―you may have a smaller undo_retention or not a huge UNDO segment that could retain all the past images (versions) needed by the existing or old transactions.

You may not have to worry about that with PostgreSQL.

Then how does PostgreSQL manage UNDO ?

In simple terms, PostgreSQL maintains both the past image and the latest image of a row in its own Table. It means, UNDO is maintained within each table . And this is done through versioning. Now, we may get a hint that, every row of PostgreSQL table has a version number. And that is absolutely correct. In order to understand how these versions are maintained within each table, you should understand the hidden columns of a table (especially xmin ) in PostgreSQL.

Understanding the Hidden Columns of a Table

When you describe a table, you would only see the columns you have added, like you see in the following log.

percona=# \d scott.employee Table "scott.employee" Column|Type| Collation | Nullable |Default ----------+------------------------+-----------+----------+------------------------------------------------ emp_id | integer| | not null | nextval('scott.employee_emp_id_seq'::regclass) emp_name | character varying(100) | || dept_id| integer| ||

However, if you look at all the columns of the table in pg_attribute, you should see several hidden columns as you see in the following log.

percona=# SELECT attname, format_type (atttypid, atttypmod) FROM pg_attribute WHERE attrelid::regclass::text='scott.employee' ORDER BY attnum; attname|format_type ----------+------------------------ tableoid | oid cmax | cid xmax | xid cmin | cid xmin | xid ctid | tid emp_id | integer emp_name | character varying(100) dept_id| integer (9 rows)

Let’s understand a few of these hidden columns in detail.

tableoid: Contains the OID of the table that contains this row. Used by queries that select from inheritance hierarchies.

More details on table inheritance can be found here : https://www.postgresql.org/docs/10/static/ddl-inherit.html

xmin: The transaction ID(xid) of the inserting transaction for this row version. Upon update, a new row version is inserted. Let’s see the following log to understand the xmin more.

percona=# select txid_current(); txid_current -------------- 646 (1 row) percona=# INSERT into scott.employee VALUES (9,'avi',9); INSERT 0 1 percona=# select xmin,xmax,cmin,cmax,* from scott.employee where emp_id = 9; xmin | xmax | cmin | cmax | emp_id | emp_name | dept_id ------+------+------+------+--------+----------+--------- 647 |0 |0 |0 |9 | avi| 9 (1 row)

As you see in the above log, the transaction ID was 646 for the command => select txid_current(). Thus, the immediate INSERT statement got a transaction ID 647. Hence, the record was assigned an xmin of 647. This means, no transaction ID that has started before the ID 647, can see this row. In other words, already running t ransactions with txid less than 647 cannot see the row inserted by txid 647.

With the above example, you should now understand that every tuple has an xmin that is assigned the txid that inserted it.

Note: the behavior may change depending on the isolation levels you choose, would be discussed later in another blog post.

xmax: This values is 0 if it was not a deleted row version. Before the DELETE is committed, the xmax of the row version changes to the ID of the transaction that has issued the DELETE. Let’s observe the following log to understand that better.

On Terminal A :We open a transaction and delete a row without committing it.

percona=# BEGIN; BEGIN percona=# select txid_current(); txid_current -------------- 655 (1 row) percona=# DELETE from scott.employee where emp_id = 10; DELETE 1

On Terminal B :Observe the xmax values before and after the delete (that has not been committed).

Before the Delete ------------------ percona=# select xmin,xmax,cmin,cmax,* from scott.employee where emp_id = 10; xmin | xmax | cmin | cmax | emp_id | emp_name | dept_id ------+------+------+------+--------+----------+--------- 649 |0 |0 |0 | 10 | avi|10 After the Delete ------------------ percona=# select xmin,xmax,cmin,cmax,* from scott.employee where emp_id = 10; xmin | xmax | cmin | cmax | emp_id | emp_name | dept_id ------+------+------+------+--------+----------+--------- 649 |655 |0 |0 | 10 | avi|10 (1 row)

As you see in the above logs, the xmax value changed to the transaction ID that has issued the delete. If you have issued a ROLLBACK, or if the transaction got aborted, xmax remains at the transaction ID that tried to DELETE it (which is 655) in this case.

Now that we understand the hidden columns xmin and xmax, let’s observe what happens after a DELETE or an UPDATE in PostgreSQL. As we discussed earlier, through the hidden columns in PostgreSQL for every table, we understand that there are multiple versions of rows maintained within each table. Let’s see the following example to understand this better.

We’ll insert 10 records to the table : scott.employee

percona=# INSERT into scott.employee VALUES (generate_series(1,10),'avi',1); INSERT 0 10

Now, let’s DELETE 5 records from the table.

percona=# DELETE from scott.employee where emp_id > 5; DELETE 5 percona=# select count(*) from scott.employee; count ------- 5 (1 row)

Now, when you check the count after DELETE, you would not see the records that have been DELETED. To see any row versions that exist in the table but are not visible, we have an extension called pageinspect. The pageinspect module provides functions that allow you to inspect the contents of database pages at a low level, which is useful for debugging purposes. Let’s create this extension to see the older row versions those have been deleted.

percona=# CREATE EXTENSION pageinspect; CREATE EXTENSION percona=# SELECT t_xmin, t_xmax, tuple_data_split('scott.employee'::regclass, t_data, t_infomask, t_infomask2, t_bits) FROM heap_page_items(get_raw_page('scott.employee', 0)); t_xmin | t_xmax |tuple_data_split
