数据库主从配置

• 主从配置

  • 进入Master库容器 docker exec -it master-mariadb-service /bin/bash

  • 打开另一个终端进入Slave容器 docker exec -it slave-mariadb-service /bin/bash

  • 进入Master /usr/bin/mysql -uroot -p 密码是root

  • 授权 GRANT REPLICATION SLAVE ON *.* TO 'slaveUser'@'10.5.0.6' IDENTIFIED BY '123456'; IP 参数代表从容器的ip

  • flush privileges;

  • show master status;

       File    | Position  | Binlog_Do_DB| Binlog_Ignore_DB
       master-bin.000005  | 635 |
    

  • 进入Slave /usr/bin/mysql -uroot -p 密码是root

  • 连接Master

        change master to master_host='10.5.0.5',
        master_user='slaveUser',
        master_password='123456',
        master_log_file='master-bin.000005', //例子，自己根据自己系统显示修改
        master_log_pos=635; //例子，自己根据自己系统显示修改
    

  • 启动Slave start slave;

  • 查看是否开启show slave status\G;

      Slave_IO_Running: Yes //这两个为yes开启成功
      Slave_SQL_Running: Yes //这两个为yes开启成功
    

  • 测试

    • 在Master中操作

        create database test;
        CREATE TABLE `admin` (
        `id` int(11) NOT NULL AUTO_INCREMENT,
        `name` varchar DEFAULT NULL COMMENT 'name',
        PRIMARY KEY (`id`));
        insert into admin values('1','name');
