mysql中使 gtid 复制跳过错误的方法

在从机查看当前执行出错的gtid

解决方法一：

(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GTIDmysql> 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。

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  Replicate_Ignore_Server_Ids:              Master_Server_Id: 2                  Master_UUID: 8f9e146f-0a18-11e7-810a-0050568833c8             Master_Info_File: /<strong>本文来源gao@daima#com搞(%代@#码网</strong>var/lib/mysql/master.info                    SQL_Delay: 0          SQL_Remaining_Delay: NULL      Slave_SQL_Running_State:            Master_Retry_Count: 86400                  Master_Bind:       Last_IO_Error_Timestamp:      Last_SQL_Error_Timestamp: 170421 17:45:11               Master_SSL_Crl:            Master_SSL_Crlpath:            Retrieved_Gtid_Set: 8f9e146f-0a18-11e7-810a-0050568833c8:1-7            Executed_Gtid_Set: 8f9e146f-0a18-11e7-810a-0050568833c8:1-6,f7c86e19-24fe-11e7-a66c-005056884f03:1                Auto_Position: 0         Replicate_Rewrite_DB:                  Channel_Name:            Master_TLS_Version: 1 row in set (0.00 sec)[root@dgt mysql]# pt-slave-restart  -S  /var/lib/mysql/mysql.sock   --error-numbers=1032   --user=root --password='bc.123456'2017-04-21T17:53:27 S=/var/lib/mysql/mysql.sock,p=...,u=root mysql-bin.000015         620 1032 2017-04-21T17:54:31 S=/var/lib/mysql/mysql.sock,p=...,u=root mysql-bin.000015        1140 1032
