前几天,发现从库挂了,具体报错信息如下: 分析思路 1. 因为我采用的是选择性复制,只针对以下几个库进行复制: card,upay,deal,monitor,collect.所以,不太可能出现对于sas_basic的操作能复制到该从库上. 2. 整个架构是1主2从,且都是选择性复制,上面这个从库是直接复制card,upay,deal,monitor,collect这几个数据库的数据,而另外一个从库则是忽略上述库,如下所示: 怀疑是在上述schema下,执行了DROP TABLE IF EXIST…

这个算不算解决,我都不太清楚,因为我感觉网上的说法,只是把错误忽略了,不表示以后用从库时不会出问题!!! 解决的办法是在从库上执行: mysql> slave stop; mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER=1; mysql> slave start; 上面的方法可以解决问题,还有一种解决问题的办法是通过修改mysql的配置文件,让从库的同步线程忽略这个错误,方法: 修改mysql配置文件 /etc/my.cnf 在 [mysqld]下加一行…
