参考 mysql搭建安装完mysql后

在master上：

1. 打开log-bin和server-id=1选项

   [root@minion-2 ~]# vi /etc/my.cnf
   log-bin
   server-id=1

2. 授权账户并重启

   mysql> grant super,reload,replication slave on ‘*.*’ to slave@192.168.0.105 identified by 'slave';
   mysql> flush privileges;
   mysql>quit
   [root@minion-2 ~]# service mysqld restart

   在slave 上：

3. 打开server-id=2和log-bin

   [root@minion-2 ~]# vi /etc/my.cnf
   log-bin
   server-id=2

4. 进入change master 功能

   mysql>change master to master_host='192.168.0.104',master_user='slave',master_password='slave';
   mysql> start slave;

至此单向的主从完毕，接下来是反过来操作一遍

在slave上：

mysql> grant super,reload,replication slave on ‘*.*’ to slave@192.168.0.104 identified by 'slave';

mysql> flush privileges;

mysql>change master to master_host='192.168.0.105',master_user='slave',master_password='slave';
mysql> start slave;
