1：安装Linux
2：修改机器名
hostname 显示主机名
[it@localhost bin]$ hostname
localhost.sohudo
编辑主机名配置文件
[it@localhost bin]$ vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=localhost.sohudo
用root登录
[it@localhost bin]$ su -
密码：
[root@localhost ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=localhost.sohudo
~
把HOSTNAME修改为it.net.cn
[html] view plain copy 在CODE上查看代码片派生到我的代码片
[it@it.net.cn ~]$ hostname
it.net.cn
3: 配置hosts文件
[it@it.net.cn ~]$ su -
密码：
[root@it.net.cn ~]# vi /etc/hosts
127.0.0.1 localhost localhost.sohudo
::1 localhost localhost.sohudo
后面加2行
10.3.7.212 it.net.cn
10.3.7.214 it02

"/etc/hosts" 4L, 120C written
