MYSQL找不到mysql.sock的处理办法

昨天安装的mysql今天忽然不能用了
[root@localhost mysql]# bin/mysqladmin -u root password root
bin/mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!

[root@localhost mysql]# bin/mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

#ps -aux | grep mysql

在网上说是找不到mysql.sock，我是通过apt-get安装的，安装后就是没找到那个文件，解决办法：
建立链接：
# ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock

这样就能正常使用了，另外：这篇文章值得一看：
