Slave_IO_Running: No 处理一例

本文介绍了解决MySQL复制过程中出现的ERROR 2002连接错误的方法。首先需要检查并清理磁盘空间,然后通过停止复制、刷新日志及更改主日志文件等步骤来同步主从服务器。

本地环境,MySQL复制报错,上去看看:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)


原来是磁盘满了,删掉一些,进去

             Slave_IO_Running: No
            Slave_SQL_Running: Yes


还是不行,因为刚才删了一些binlog。

slave stop;

flush logs;

CHANGE MASTER TO MASTER_LOG_FILE='xxxxxx.xxxx',MASTER_LOG_POS=xxxx;  (从master那边查询)

start slave;


两边都这么处理一下,正常。
