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

Question

阿里云服务器centos上，MySQL报错ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' 问题怎样解决？

Answer 1

这个问题一般是你的mysql没起来，运行命令

ps aux | grep mysql

看看mysql进程起来没，没起来就/etc/init.d/mysql start一下

Answer 2

你去看Error log的最后几行
配置文件有问题、剩余空间不够都会造成无法启动
