## mysql主从不同步，提示Last\_Error: Coordinator stopped because there were error(s) in the worker(s). The most recent failure being: Worker 1 failed executing transaction ##

昨天zabbix突然发送告警信息，告警说是mysql的slave停掉了，登录到数据库从库，进去看mysql的进程是正常的，然后去看下mysql的error日志

1，进入数据库查看主从状态 show slave status\\G;  
根据提示查询到的错误信息  
Last\_Error: Coordinator stopped because there were error(s) in the worker(s). The most recent failure being: Worker 1 failed executing transaction ‘d393d2e3-9b61-11e5-82bf-141877342ba0:171661170’ at master log mysql-bin.000063, end\_log\_pos 171661170. See error log and/or performance\_schema.replication\_applier\_status\_by\_worker table for more details about this failure or others, if any.

2，根据上图的提示，查询到的异常数据出现在opp\_strack表中  
select \* from performance\_schema.replication\_applier\_status\_by\_worker\\G；  
确定事务发生在表 opp\_strack 上，定位到表,再去排查是哪一条记录

3，去主库的对应的binlog日志中去查找数据库操作记录  
mysqlbinlog --no-defaults -v -v --base64-output=decode-rows /zdata/mysql\_data/mysql-bin.000063 | grep -A 20 “171661170” --color

–/zdata/mysql\_data/mysql-bin.000063是在主从状态中查找的

binlog日志中查询到opp\_strack表的更新操作，然后对比主从库opp\_strack表中字段“1683”的数据，我这边得到的数据是不一致的，发现从库opp\_strack中被插入进来三条数据，冲掉了主库的id值，然后将从库中的三条数据删除掉

4，主从数据恢复一致后需要在slave上跳过报错的事务  
在从库中执行  
Stop slave;  
Set @@SESSION.GTID\_NEXT=’ d393d2e3-9b61-11e5-82bf-141877342ba0:171661170’  
Begin;  
Commit;  
Set @@SESSION.GTID\_NEXT = AUTOMATIC;  
Start slave;  
再次查看从库状态，恢复正常即解决  
Show slave status\\G
