一、配置主服务器

  1.my.ini中添加内容

  

  2.创建“复制权限”的账号

      创建账号

   

   

         给创建的账号授予“待复制数据库”上所有的操作权限

   

         查看所有用户

SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;
Copy after login

   

   查看用户权限

   

  3.重启mysql服务

二、配置从服务器

  1.my.ini中添加内容

    

   注:从库my.ini的配置中,Mysql5.5版本以上不再支持master的用法,比如5.1

    中可用的(master-user = repl;master-password = repl;master-port = 3307),

    如果在mysql5.5版本以上中使用该语法会导致,mysql服务无法启动。

  2.重启mysql服务器

    3.开启从库复制功能

       a)关闭从库复制功能

stop slave;
Copy after login

  

   b)设置主库连接串

change master to  master_host="10.0.0.10",  master_port=3306,  master_user="slave1",  master_password="feng" ;
Copy after login

  

      注:出现警告是没关系的,只是密码是明文等提示。

            此处还可指明“主库”二进制文件名和位置

    eg:

      查看主库信息可用以下命令完成:

     

   c)打开从库复制功能

start slave;
Copy after login

   

   d)查看从库状态

   

三、测试

      1.连接到主库上,插入一行数据

  

  

  2.在从库上执行查询
