MySQL8.0.36 GTID主从同步失败排查

报错信息：

  Last_SQL_Error: Coordinator stopped because there were error(s) in the worker(s). The most recent failure being: Worker 1 failed executing transaction '6f577885-e5d0-11ee-a94a-0242c0a80067:1' at source log 7364ffd6441c-bin.000006, end_log_pos 724. See error log and/or performance_schema.replication_applier_status_by_worker table for more details about this failure or others, if any.

根据报错信息查看具体内容

select * from performance_schema.replication_applier_status_by_worker\G

解析binlog日志查看

 mysqlbinlog -vvv 7364ffd6441c-bin.000006

 看起来因该是主库的的一个school库被手动删除，而从库中没有这个school导致binlog不一致出现报错，那么只要在从库中将这个事务手动的跳过即可

首先停止线程

stop slave;

跳过事务

set @@session.gtid_next='6f577885-e5d0-11ee-a94a-0242c0a80067:1';
begin;
commit;
Set @@SESSION.GTID_NEXT = AUTOMATIC;

启动线程检查复制关系

start slave;
show slave status\G
