方法1：

(1)停止slave进程

mysql> STOP SLAVE;

(2)设置事务号，事务号从Retrieved_Gtid_Set获取

在session里设置gtid_next，即跳过这个GTID

mysql> SET @@SESSION.GTID_NEXT= '8f9e146f-0a18-11e7-810a-0050568833c8:4'

（3）设置空事物

mysql> BEGIN; COMMIT;

（4）恢复事物号

mysql> SET SESSION GTID_NEXT = AUTOMATIC;

(5)启动slave进程

mysql> START SLAVE;

解决办法二：重置master方法跳过错误

mysql>  STOP SLAVE;

mysql> RESET MASTER;

mysql>   SET @@GLOBAL.GTID_PURGED ='8f9e146f-0a18-11e7-810a-0050568833c8:1-4'

mysql>  START SLAVE;

上面这些命令的用意是，忽略8f9e146f-0a18-11e7-810a-0050568833c8:1-4 这个GTID事务，下一次事务接着从 5 这个GTID开始，即可跳过上述错误。

[b]解决办法三：使用pt-slave-restart工具
[/b]

pt-slave-restart工具的作用是监视某些特定的复制错误，然后忽略，并且再次启动SLAVE进程（Watch and restart MySQL replication after errors）。

忽略所有1062错误，并再次启动SLAVE进程

[root@dgt mysql]# pt-slave-resetart -S /var/lib/mysql/mysql.sock —error-numbers=1062

检查到错误信息只要包含 test.t1，就一概忽略，并再次启动 SLAVE 进程

[root@dgt mysql]# pt-slave-resetart -S /var/lib/mysql/mysql.sock  —error-text=”test.t1”

下面举例解决错误问题号

            Last_SQL_Error: Could not execute Delete_rows event on table test.t; Can't find record in 't', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.000028, end_log_pos 1862
