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
