Linux下更改计算机名 HOSTNAME=计算机名

昨天装redhat的时候计算机名没有做特殊修改，默认为localhost，今晚想起来改成了网站的老域名＠LayoutCN。 需要修改/etc/sysconfig/network和/etc/hosts 两个文件。可以参考如下步骤

1. [loongsky@LayoutCN ~]$ vi /etc/sysconfig/network
   NETWORKING=yes
   NETWORKING_IPV6=no
   HOSTNAME=LayoutCN
2. [loongsky@LayoutCN ~]$ vi /etc/hosts
   # Do not remove the following line, or various programs
   # that require network functionality will fail.
   #127.0.0.1              localhost.localdomain localhost
   192.168.1.4     LayoutCN        LayoutCN
