故障原因:
开发人员在主库上修改了一张表的结构,加了一个字段,从库由于各种原因没有同步过去,导致主从同步失败。

故障处理:
1,查看在从库上查看同步状态:

2,从上面可以看出表act_id的js_code字段在从库上没有,可以对比一下主库和从库这张表的结构

3,在正式处理故障之前要停掉主库和从库的从属进程(我的环境是做了双向同步,即主主同步)

1
2
mysql> slave stop;
Query OK, 0 rows affected (0.12 sec)

如图4所示,在从库上加缺少的字段:

1
alter table act_id add js_code text not Null AFTER fields;

5,启动从库的从属进程,查看主从状态:
