找到配置模板：
CHANGE MASTER TO
MASTER_HOST='master2.example.com',
MASTER_USER='replication',
MASTER_PASSWORD='password',
MASTER_PORT=3306,
MASTER_LOG_FILE='master2-bin.001',
MASTER_LOG_POS=4,
MASTER_CONNECT_RETRY=10;
3308，3309使用如下配置：
CHANGE MASTER TO
MASTER_HOST='192.168.84.30',
MASTER_USER='repl',
MASTER_PASSWORD='123',
MASTER_PORT=3307,
master_auto_position=1;
开始配置3308
mysql> CHANGE MASTER TO
-> MASTER_HOST='192.168.84.30',
-> MASTER_USER='repl',
-> MASTER_PASSWORD='123',
-> MASTER_PORT=3307,
-> master_auto_position=1;
Query OK, 0 rows affected, 2 warnings (0.00 sec)
开始配置3309
mysql> CHANGE MASTER TO
-> MASTER_HOST='192.168.84.30',
-> MASTER_USER='repl',
-> MASTER_PASSWORD='123',
-> MASTER_PORT=3307,
-> master_auto_position=1;
Query OK, 0 rows affected, 2 warnings (0.00 sec)mysql> show slave status \G; 查看slave状态
mysql> show slave status \G;
