在Master节点上查看二进制日志的位置  
 mysql> show master status;  
\+------------------+----------+--------------+------------------+-------------------+  
| File             | Position | Binlog\_Do\_DB | Binlog\_Ignore\_DB | Executed\_Gtid\_Set |  
\+------------------+----------+--------------+------------------+-------------------+  
| mysql-bin.000011 |     1734 |              |                  |                   |  
\+------------------+----------+--------------+------------------+-------------------+  
1 row in set (0.00 sec)

解决方法：   
除非主库有二进制日志备份，否则需要重建Slave节点
