CentOS yum安装mysql后 Can’t connect to local MySQL server through socket ‘/var/lib/

CentOS Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’

如果仅仅只yum 安装了mysql这个包，启动mysql时就会提示：
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’

yum安装mysql这个包其实是MySQL 客户端程序和共享库，所以我们还需要安装php-mysql和mysql-server这两个包.
