Mysql主从库同步错误：1062 Error 'Duplicate entry '1438019'

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

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

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.

一种粗暴快速的解决mysql主从不同步错误的思路

mysql主从经常会出现主从数据不同步的问题,脏数据会造成主从同步中断, 出现大量ERROR,如1032,1062等错误.常规方法是逐条删除脏数据或者 重做库,由于数据量大操作麻烦,而且主库在线上运行不能有锁表操作, 各种不便特别费时间.笔者在生产环境遭遇了一次,情急之下用粗暴的方法 不到10分种解决问题.下面假设一种情况,主库正常,从库数据不一致, 解决思路步骤如下: 1 ,对故障定性,通过查看最近日志来找出蛛丝马迹.一般都用mysqlbinlog /var/lib/myql/mysqld-b

MySQL从库上有一个IO线程负责从主库取binlog到写到本地.另外有一个SQL线程负责执行这些本地日志,实现命令重放: 一.环境 主机: master操作系统:centos 5.3 IP:192.168.1.222 MySQL版本:5.0.77 从机: slave操作系统:centos 5.3 IP:192.168.1.220 MySQL版本:5.0.77 二.创建数据库 分别登录master机和slave机的mysql:mysql –u root –p 创建数据库:create datab
