一、系统环境

root@ubuntu:/# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu @H_301_28@14.04.@H_301_28@4 LTS
Release:    @H_301_28@14.04
Codename:   trusty
root@ubuntu:/# uname -a
Linux ubuntu @H_301_28@4.2.@H_301_28@0-@H_301_28@42-generic #49~14.04.1-Ubuntu SMP Wed Jun 29 20:22:11 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
root@ubuntu:/# 

二、静态IP设置
2.1 方法一： 直接编辑 /etc/network/interfaces 文件

auto lo  
iface lo inet loopback  

# The primary network interface 
auto eth0  
iface eth0 inet static  
address @H_301_28@192.168.0.224   #IP地址
network @H_301_28@192.168.0.0     #网络地址
netmask @H_301_28@255.255.255.0   #子网掩码
broadcast @H_301_28@192.168.0.255 #广播地址 
gateway @H_301_28@192.168.0.1     #网关
dns-nameservers @H_301_28@114.114.114.114  #DNS服务器

2.2 方法二：图形界面下直接在network-manager中配置

最终形成的文件如下

root@ubuntu:/# cat  /etc/NetworkManager/system-connections/Ethernet\ connection\ @H_301_28@1 
[@H_301_28@802-@H_301_28@3-ethernet]
