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

转载：http://zhuomuniaojingshen.blog.hexun.com/85106503_d.html

mysql主从库在同步时会发生1062 Last_SQL_Error: Error ‘Duplicate entry ‘的问题：

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：

ERROR:

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 slave_skip_errors = 1062 ,保存.重启mysql. mysql slave可以正常同步了.
