一、系统环境

root@ubuntu:/# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.4 LTS
Release:    14.04
Codename:   trusty
root@ubuntu:/# uname -a
Linux ubuntu 4.2.0-42-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 192.168.0.224   #IP地址
network 192.168.0.0     #网络地址
netmask 255.255.255.0   #子网掩码
broadcast 192.168.0.255 #广播地址 
gateway 192.168.0.1     #网关
dns-nameservers 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\ 1 
[802-3-ethernet]
duplex=full
mac-address=00:0C:29:41:36:XX

[connection]
id=IP_48
uuid=18e73f13-585b-433a-822e-a9a14e41xxxx
type=802-3-ethernet
timestamp=1495197724

[ipv6]
method=auto [ipv4] method=manual dns=114.114.114.114;
dns-search=202.106.196.115;
address1=192.168.0.48/24,192.168.0.1
