mysql 主从复制

 

 

 

 

 

 

一,前言

　　配置前确定服务器mysql高度一样

　　并启动数据库;

 

二, 修改主服务器配置

    
       [mysqld]
       log-bin=mysql-bin    //[必须]启用二进制日志
       server-id=1       //[必须]服务器唯一ID，默认是1，一般取IP最后一段

 三,修改从库服务器

     
       [mysqld]
       log-bin=mysql-bin   //[不是必须]启用二进制日志
       server-id=2      //[必须]服务器唯一ID，默认是1，一般取IP最后一段

四,  更改了配置需要重启

五, 主服务器授权用户

　　  

　　  

　　grant replication slave on *.* to 'myimport'@'%' identified by '123456';

六, 从库启用

　　

　　  change master to master_host='10.0.0.51',master_user='myimport',master_password='123456',master_log_file='mysql-bin.000003',master_log_pos=322;
