一、Master1的配置

（1）修改Master1配置文件/etc/my.cnf，修改如下：

log-bin = /usr/local/mysqllogs/binlogs/master1-bin #啟用二進制日志 relay-log = /usr/local/mysqllogs/relaylogs/relay-bin #啟用中繼日志 auto-increment-offset = 1 #自增起始值 auto-increment-increment = 2 #自增步長 server-id = 1

重啟數據庫服務

（2）創建有復制權限的用戶，命令如下

CREATE USER 'luccy'@'10.10.3.212' IDENTIFIED BY '123456'; REVOKE ALL PRIVILEGES ,GRANT OPTION FROM 'luccy'@'10.10.3.212'; GRANT RELOAD,LOCK TABLES, REPLICATION CLIENT ,REPLICATION SLAVE ON *.* TO 'luccy'@'10.10.3.212'; FLUSH PRIVILEGES;

二、Master2的配置

（1）修改Master1配置文件/etc/my.cnf，修改如下：

log-bin = /usr/local/mysqllogs/binlogs/master2-bin relay-log = /usr/local/mysqllogs/relaylogs/relay-bin auto-increment-offset = 2 auto-increment-increment = 2 server-id = 2

重啟數據庫服務

（2）創建有復制權限的用戶，命令如下

CREATE USER 'jerry'@'10.10.3.211' IDENTIFIED BY '123456'; REVOKE ALL PRIVILEGES ,GRANT OPTION FROM 'jerry'@'10.10.3.211'; GRANT RELOAD,LOCK TABLES, REPLICATION CLIENT ,REPLICATION SLAVE ON *.* TO 'jerry'@'10.10.3.211'; FLUSH PRIVILEGES;

三、查看Master1和Master2的狀態

SHOW MASTER STATUS;

Master1

Master2

四、互相指向

CHANGE MASTER TO MASTER_USER='jerry',MASTER_HOST='10.10.3.212',MASTER_PASSWORD='123456',MASTER_LOG_FILE='master2-bin.000002',MASTER_LOG_POS=982;

CHANGE MASTER TO MASTER_USER='luccy',MASTER_HOST='10.10.3.211',MASTER_PASSWORD='123456',MASTER_LOG_FILE='master1-bin.000001',MASTER_LOG_POS=1473;

五、啟動Master1和Master2服務器復制進程

START SLAVE;

Master1

Master2

六、測試
