在Linux   CentOS 5 中安装完MySQL （server、devel）之后进行初始化

service mysqld  start ,执行命令报错：

Neither host 'localhost.localdomain' nor 'localhost' could be looked up with

/usr/bin/resolveip

Please configure the 'hostname' command to return a correct hostname.

错误： 

解决办法

1、查看/etc/hosts，内容如下：

# Do not remove the following line, or various programs

# that require network functionality will fail.

::1 localhost.localdomain localhost

2、将::1修改为127.0.0.1后，启动成功。
