1、修改/etc/network/interfaces文件：

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet static

address 192.168.1.200

netmask 255.255.255.0

broadcast 192.168.1.255

gateway 192.168.1.1

2、更改DNS：修改/etc/resolv.conf

nameserver 114.114.114.114

?不起作用，查看/etc/resolv.conf有以下提示：

#?Dynamic resolv.conf(5)?fileforglibc resolver(3)?generated by resolvconf(8)# ? DO?NOT?EDIT?THIS?FILE?BY?HAND?--?YOUR?CHANGES?WILL?BE?OVERWRITTEN

新建一個文件，文件名必須為"tail"

sudo vim?/etc/resolvconf/resolv.conf.d/tail

加入兩行：

nameserver 8.8.8.8

nameserver?114.114.114.114

保存

sudo?/etc/init.d/resolvconf stop && ? /etc/init.d/resolvconf start

3、重啟網卡：sudo?/etc/init.d/networking stop?

? ? ?sudo /etc/init.d/networking start
