MySQL-VIP：192.168.1.200

2 MySQL-master1：192.168.1.201

3 MySQL-master2：192.168.1.202

4

5 OS版本：CentOS 5.4

6 MySQL版本：5.0.89

7 Keepalived版本：1.1.20

一、MySQL master-master配置

1、修改MySQL配置文件

两台MySQL均如要开启binlog日志功能，开启方法：在MySQL配置文件[MySQLd]段中加上log-bin=MySQL-bin选项

两台MySQL的server-ID不能一样，默认情况下两台MySQL的serverID都是1，需将其中一台修改为2即可

2、将192.168.1.201设为192.168.1.202的主服务器

在192.168.1.201上新建授权用户
