Ubuntu 1404设置静态IP

编辑修改interfaces文件

sudo vim /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0

#——————shielding DHCP
#iface eth0 inet dhcp
#——————add your setting here
iface eth0 inet static
address 192.168.1.214
gateway 192.168.1.1
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255

修改DNS

resolv.conf 这个文件DHCP获取后自动改写，这里我没有修改，原来已经通过DHCP获取了一个，贸然填上8.8.8.8谷歌的，可能还会缓慢

sudo vim /etc/resolv.conf

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 49.223.187.120
nameserver 175.190.255.50
search DHCP HOST

重启网卡

一般使用

sudo service networking restart

或者

sudo /etc/init.d/networking restart

这两个命令都可以重启网卡，重新载入配置，但是在这个Ubuntu 1404 server版本中，没有任何反应，还是原来DHCP获取的IP，通过关闭和开启网卡可以，没有搞清楚原因

ifconfig eth0 down
ifconfig eth0 up
