MySQL互為主從配置

編輯:MySQL綜合教程

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

  兩台MySQL均如要開啟binlog日志功能,開啟方法:在MySQL配置文件[MySQLd]段中加上log-bin=MySQL-bin選項

  兩台MySQL的server-ID不能一樣,默認情況下兩台MySQL的serverID都是1,需將其中一台修改為2即可

  2、將192.168.1.201設為192.168.1.202的主服務器

  在192.168.1.201上新建授權用戶
