环境描述：

OS：CentOS6.5_X64

MASTER：192.168.0.202

BACKUP：192.168.0.203

VIP：192.168.0.204

1、配置两台Mysql主主同步

[root@master ~]# yum install mysql-server mysql -y [root@master ~]# service mysqld start [root@master ~]# mysqladmin -u root password 123.com [root@master ~]# vi /etc/my.cnf #开启二进制日志，设置id [mysqld] log-bin=mysql-bin server-id=1 #backup这台设置2 [root@master ~]# service mysqld restart

#先查看下log bin日志和pos值位置

master配置如下：

[root@ master ~]# mysql -u root -p123.com mysql> GRANT REPLICATION SLAVE ON *.* TO 'replication'@'192.168.0.%' IDENTIFIED BY 'replication'; mysql> flush privileges; mysql> change master to -> master_host='192.168.0.203', -> master_user='replication', -> master_password='replication', -> master_log_file='mysql-bin.000002', -> master_log_pos=106; #对端状态显示的值 mysql> start slave; #启动同步

backup配置如下：

[root@backup ~]# mysql -u root -p123.com mysql> GRANT REPLICATION SLAVE ON *.* TO 'replication'@'192.168.0.%' IDENTIFIED BY 'replication'; mysql> flush privileges; mysql> change master to -> master_host='192.168.0.202', -> master_user='replication', -> master_password='replication', -> master_log_file='mysql-bin.000002', -> master_log_pos=106; mysql> start slave;
