SQL是Structured Query Language(结构化查询语言)的缩写。SQL是专为数据库而建立的操作命令集,是一种功能齐全的数据库语言。在使用它时,只需要发出“做什么”的命令,“怎么做”是不用使用者考虑的。SQL功能强大、简单易学、使用方便,已经成为了数据库操作的基础,并且现在几乎所有的数据库均支持SQL。 在从机查看当前执行出错的gtid mysql> show slave status \G

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。
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

2017-04-21T17:54:31 S=/var/lib/mysql/mysql.sock,p=...,u=root mysql-bin.000015 1140 1032 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 以上就是mysql中使 gtid 复制跳过错误的方法的详细内容,更多请关注php中文网其它相关文章!
