ubuntu 14.04如何配置固定IP

1，编辑interfaces文件

$sudo vim /etc/network/interfaces
添加：

#the primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.150
netmask 255.255.255.0
gateway 192.168.1.1
2，添加DNS

$sudo vim /etc/resolv.conf
添加：

nameserver 192.168.1.1
nameserver 114.114.114.114
3，修改文件使其永久不变

$sudo vim /etc/resolvconf/resolv.conf.d/base
添加：

nameserver 192.168.1.1
nameserver 114.114.114.114
4，将/etc/NetworkManager目录下的system-connections删除或者备注为其他名字

5，重启
