搭建MySQL的主主复制步骤(请看链接 )
目的
配置MYSQL服务器实现主主复制。
实验环境
服务器1(以下简称S1):
IP:192.168.1.88
服务器2(以下简称S2):
IP:192.168.1.89
OS:CentOS 6.2 32
MYSQL:5.1.73
配置
# 先停止S1和S2的iptables防火墙。
service iptables stop
# 修改S1的/etc/my.cnf文件,在[mysqld]字段下添加以下内容:
log-bin=mysql-bin
log-slave-updates
server-id=1
# 同理,修改S2的/etc/my.cnf文件,在[mysqld]字段下添加以下内容(注意server-id不能一样):
log-bin=mysql-bin
log-slave-updates
server-id=2
# 重启S1和S2的mysqld服务。
service mysqld restart
# 登录S2的数据库,执行锁表命令,防止在查看二进制日志文件时有人对数据进行修改操作,然后再执行查看命令,记录二进制日志文件名和当前位置。
mysql> flush tables with read lock;
Query OK, 0 rows affected (0.00 sec)
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000003 | 191 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
# 登录S1的数据库,创建用于复制的用户并将S2配置成主复制服务器(读者注意根据实际情况修改具体参数)。
mysql> grant replication slave on *.* to 'slave'@'192.168.1.89' identified by '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> change master to master_host='192.168.1.89',master_user='slave',master_password='123456',master_log_file='mysql-bin.000003',master_log_pos=191;
Query OK, 0 rows affected (0.05 sec)
# 在S1的数据库上执行锁表和查看二进制日志文件信息的命令。
mysql> flush tables with read lock;
Query OK, 0 rows affected (0.00 sec)
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000003 | 260 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
# 在S2的数据库执行解锁表命令,并创建用于复制的用户并将S1配置成主复制服务器。
mysql> unlock tables;
Query OK, 0 rows affected (0.00 sec)
mysql> grant replication slave on *.* to 'slave'@'192.168.1.88' identified by '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> change master to master_host='192.168.1.88',master_user='slave',master_password='123456',master_log_file='mysql-bin.000003',master_log_pos=260;
Query OK, 0 rows affected (0.03 sec)
# 在S1的数据库执行解锁表命令,并启动复制。
mysql> unlock tables;
Query OK, 0 rows affected (0.00 sec)
mysql> start slave;
Query OK, 0 rows affected (0.00 sec)
# 在S2的数据库启动复制。
mysql> start slave;
Query OK, 0 rows affected (0.00 sec)
# 最后,,执行show slave status;命令可以查看配置是否成功,如果下面这两个为YES即为成功。
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
# 读者也可以通过创建数据库等操作来验证是否同步。

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

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

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.

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.

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.

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.

Through the Go standard library database/sql package, you can connect to remote databases such as MySQL, PostgreSQL or SQLite: create a connection string containing database connection information. Use the sql.Open() function to open a database connection. Perform database operations such as SQL queries and insert operations. Use defer to close the database connection to release resources.
