多服务器MYSQL数据同步_MySQL
bitsCN.com 两台服务器A:192.168.1.1B:192.168.1.2A(master)作为主服务器 为 B(slave)提供同步服务。 关闭A,B服务器的数据库,将服务器A的数据库导出至B服务器上,保证A,B服务器上要同步的数据库结构相同; 1、修改A服务器的配置文件my.cnf(win 服务器为 my.ini) #skip-networking #注释掉 因为它是屏蔽掉一切TCP/IP连接 server-id=1log-binbinlog-do-db=backup_db #提供数据同步服务的数据库set-variable=binlog-ignore-db=mysql #不记录数据库mysql的更新日志 2、在A服务器上增加一个账号专门用于同步,如下: # /usr/local/mysql/bin/mysql -h192.168.1.1 -uroot -p***** mysql>GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO name@192.168.1.2 IDENTIFIED BY 'pw'; 3、在B服务器, 修改配置文件my.cnf(win 服务器为 my.ini) server-id=2 #不能与A配置相同master-host=192.168.1.1 #主机A的地址master-user=name #主机A提供给B的用户,该用户中需要包括数据库backup_db的权限master-password=pw #访问密码 master-port=3306 #端口,主机的MYSQL端口master-connect-retry=60 #重试间隔60秒set-variable=replicate-ignore-db=mysql #略过同步的数据库名,如果有多个,请设置多次set-variable=replicate-do-db=backup_db #想要同步的数据库名,如果有多个,请设置多次 4、在Slave上检验一下是否能正确连接到Master上,并且具备相应的权限。# /usr/local/mysql/bin/mysql -h192.168.1.1 -uname -ppw mysql>SHOW GRANTS; +----------------------------------------------------------------------------------------------------------------------------------------------------+| Grants for name@192.168.1.2 |+----------------------------------------------------------------------------------------------------------------------------------------------------+| GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'name@192.168.1.2' IDENTIFIED BY PASSWORD '*4498909FB5F32638296EFBA1886F56599F142787' |+----------------------------------------------------------------------------------------------------------------------------------------------------+1 row in set (0.53 sec) mysql> 5、启动Slave,登录Slave,查看一下同步状态:# mysql -uroot mysql>SHOW SLAVE STATUS/G 看到 Slave_IO_Running: YesSlave_SQL_Running: Yes 配置成功,在A服务器上添加一条数据,看看B是不是同步过来了! 作者 MrLee23 bitsCN.com

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.
