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

一:bug截圖

[root@server2 hive1.21]# mysql -uroot -p

Enter password:

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

 

二:原因分析

mysql是否啓動成功

 

發現mysql啓動失敗

server quit without updating PID file (/var/lib/mysql/server2.pid).

重新啓動過服務器,是否出現殭屍進程哩

三:解決方案

先查看mysql的進程

ps -ef | grep mysql

 

殺死進程,然後重新啓動mysql即可

再次連接
