解决mysal出错问题

安装MySql出错信息，郁闷了一个晚上，终于解决了，一下是出错信息：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
[root@localhost init.d]# mysql_install_db
Neither host 'localhost' nor 'localhost' could be looked up with
/usr/bin/resolveip
Please configure the 'hostname' command to return a correct hostname.
If you want to solve this at a later stage, restart this script with
the --force option
解决办法是：
hostname 127.0.0.1，这样再次启动service mysqld start就可以了，终于跑起来了，高兴，现在phpmyadmin也能够用了，下一步该往下开发了。
