如图所示，slave_io_runnind:no,slave_sql_running:yes

此时，主从配置错误，我们可以查看Last_IO_Error:来查看报错信息

 此时，我们需要停止从服务器的主从服务，

mysql> stop slave;
Query OK, 0 rows affected, 1 warning (0.00 sec)

到master机器登陆mysql：

记录master的bin的位置，例如：

mysql> show master status;

 必要时使用flush log;进行刷新

然后。我们到从服务器进行修改

mysql> stop slave;
Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> change master to master_log_file='service-bin.000004',master_log_pos=157;
Query OK, 0 rows affected, 3 warnings (0.01 sec)mysql> change master to master_host='master1',master_user='rep',master_password='Wyxbuke00.',master_log_file='service-bin.000004';
Query OK, 0 rows affected, 8 warnings (0.02 sec)mysql> start slave;
Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> show slave status\G;
