操作系統：中標Linux
Mysql版本：mysql-server.i386 0:5.0.45-7.el5
（注：安裝mysql是用的yum命令）
Mysql1端 IP 192.168.2.122
Mysql2端 IP 192.168.2.123
數據庫：test
1.Mysql1設置:
1.1 設置Mysql Replication
1.增加一用於數據庫同步的用戶root
mysql>GRANT REPLICATION SLAVE,REPLICATIONCLIENT,RELOAD,SUPER ON *.* TO 'root'@'192.168.2.123' IDENTIFIED BY'password';
(授與從192.168.2.123主機上登錄用戶root數據複製權限)
2.使權限生效，這步可不做，因爲過會要重啓mysql
mysql>flush privileges;
3.退出mysql命令行界面
mysql> exit
4.停止mysql服務
service mysqld stop
5.更改Mysql配置文件/etc/my.cnf
打開mysql配置文件
vi /etc/my.cnf
在配置文件中添加以下內容
[mysqld]
#master
log-bin
server-id=1
binlog-do-db= vtigercrm510
#slave
master-host = 192.168.2.120
master-user = root
master-password = password
master-port = 3306
master-connect-retry = 10
replicate-do-db = test
6.啓動Mysql
service mysqld start
2.Mysql2設置:
1.更改Mysql配置文件/etc/my.cnf
打開Mysql的配置文件
vi /etc/my.cnf
在配置文件中添加以下內容
[mysqld]
#master
log-bin
server-id=2
binlog-do-db= vtigercrm510
#slave
master-host = 192.168.2.118
master-user = root
master-password = password
master-port = 3306
master-connect-retry = 10
replicate-do-db = vtigercrm510
2.重新啓動Mysql服務
service mysqld restart
3.Mysql1設置:
1.分別在mysql1和mysql2上啓動slave
mysql> START SLAVE;
2.查看slave狀態：
mysql> show slave status\G;
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
如果都是yes，代表已經在同步
3.查看mster狀態
mysql> Show master status;
Mysql設置完畢
