ERROR2002(HY000):Can'tconnecttolocalMySQLse_MySQL

顺手打开终端执行mysql，很不幸，报错

root@kali:~# mysqlERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

此时博主忽然想到大神 ： Lellansin's 冰森（http://www.lellansin.com/） 博客上好像有这样一篇博文，仔细阅读之，他那篇文章中所描诉的情况是磁盘被占满导致的。但是我这磁盘明显是够用的。蛋疼ing...

按照以往的经验，博主必然会选择重启。当然，这次也不例外，执行

service mysql restart

[FAIL] MySQL server PID file could not be found! ... failed!Starting MySQL[ o.

我那个擦!!!

ps -ef|grep mysql

博主记录这个过程旨在说明出现

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

这个错误也有可能是mysql的进程没起来的原因。
