mysql> change master to master_host='192.168.24.129',master_user='backup',master_port=3307,master_password='backup',master_log_file='mysql-bin.000007',master_log_pos=154 for channel 'master_2';

Query OK, 0 rows affected, 2 warnings (0.04 sec)

启动slave操作

可以通过start slave的方式去启动所有的复制，也可以通过单个复制源的方式，下面介绍单个复制的的启动演示

mysql> start slave for channel 'master_1';

Query OK, 0 rows affected (0.01 sec)

mysql> start slave for channel 'master_2';

Query OK, 0 rows affected (0.02 sec)

查看同步状态

正常启动后，可以查看同步的状态，执行show slave status for channel ‘channel_name\G’查看复制源master_1的同步状态；

mysql> show slave status for channel 'master_1'\G
