摘要: mysql主从库同步错误：1062 Error 'Duplicate entry '1438019' for key 'PRIMARY'' on query

mysql主从库同步错误：1062 Error 'Duplicate entry '1438019' for key 'PRIMARY'' on query ... 的问题的解决方案。

显然这个问题是因为插入重复主键导致从库不工作了，错误消息如下

解决的办法：

修改mysql配置文件 /etc/my.cnf 在 [mysqld]下加一行 slave_skip_errors = 1062 ,保存.重启mysql. mysql slave可以正常同步了.
