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
1、MySQL master-master配置
1、改正MySQL配置文件
两台MySQL均如要开启binlog日记功效,开启办法: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,默许情形下两台MySQL的serverID都是1,需将此中一台改正成2便可
2、将192.168.1.201设为192.168.1.202的主服务器
在192.168.1.201上新建受权用户
