在show slave status G中

可见从201到209这九个事务出错，如何跳过？一次跳一个
解决办法一
mysql> stop slave;
Query OK, 0 rows affected (0.00 sec)
mysql> set session gtid_next= '59222b34-04f6-11ea-8e77-02000aba408a:201';
Query OK, 0 rows affected (0.00 sec)
mysql> begin;
Query OK, 0 rows affected (0.00 sec)
mysql> commit;
Query OK, 0 rows affected (0.00 sec)
mysql> set session gtid_next=automatic;
Query OK, 0 rows affected (0.00 sec)
mysql> start slave;
Query OK, 0 rows affected (0.00 sec)
mysql> show slave status G
或者
解决办法二
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。
解决办法三：使用pt-slave-restart工具
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

参数解释：
--slave-password=s Sets the password to be used to connect to the slaves
--slave-user=s Sets the user to be used to connect to the slaves
--sleep=i Initial sleep seconds between checking the slave ( default 1)
--socket=s -S Socket file to use for connection=
--password=s -p Password to use when connecting
pt-slave-resetart -S./mysql.sock —error-numbers=1032
--error-numbers=h Only restart this comma-separated list of errors
--host=s -h Connect to host
--user=s -u User for login if not current user
