LNMP的mysql不能启动了报两个错误

lovelykid

1.直接在vps输入mysql会提示错误ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

2.通过/etc/init.d/mysql start启动提示下面的错误
. * The server quit without updating PID file (/var/run/mysqld/mysqld.pid).

因为最近学着打站，所以用的是军哥的lnmp一键包
然后第一玩vps，安装好的时候都是一切OK然后在vps的后台更改过一次hostname（原始的是JovialDirect-VM，更改为了自己的名字），然后貌似数据库就出错了。


下面是错误日志，军哥能帮忙看看什么问题吗？google搜了上面的两个错误，所有的方法都试过了。都没有用。不知道如何解决了。

licess

可能有通过其他方式安装的mysql干扰造成的

centos的话：rpm -qa|grep mysql
debian/ubuntu的话：dpkg -l|grep mysql 看一下
