周末机房迁移,直接停了服务器了,周一来发现mysql启动不了.信息如下
sudo /etc/init.d/mysqld restart Stopping mysqld: [ OK ] Another MySQL daemon already running with the same unix socket. Starting mysqld: [FAILED]
在日志里找相关的信息也没有找到,可能是找的日志路径不对.
在百度上找了相关的资料,在一篇文章中解决了这个问题.

以下为文章内容
在国外网站发现的解决方法。 原因多个MySQL进程使用了同一个socket。 两个方法解决: 第一个是立即关机 使用命令 shutdown -h now 关机,关机后在启动,进程就停止了。 第二个直接把mysql.sock文件改名即可。也可以删除,推荐改名。 然后就可以启动mysql了。 下面是国外原文 To prevent the problem from occurring, you must perform a graceful shutdown of the server from the command line rather than powering off the server. # shutdown -h now This will stop the running services before powering down the machine. Based on Centos, an additional method for getting it back up again when you run into this problem is to move mysql.sock: # mv /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock.bak # service mysqld start Restarting the service creates a new entry called mqsql.sock
解决问题的命令即是
mv /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock.bak service mysqld start
