Ubuntu的网络参数保存在文件 /etc/network/interfaces中，默认设置使用dhcp，内容如下：

# The primary network interface

auto eth0

iface eth0 inet dhcp

设置静态ip的方法如下：

(1)编辑 /etc/network/interfaces

1.1)将dhcp 一行屏蔽

# The primary network interface

auto eth0

#iface eth0 inet dhcp

1.2)添加和静态ip有关的参数

# The primary network interface

iface eth0 inet static

address 192.168.0.10

netmask 255.255.255.0

gateway 192.168.0.1

(2)编辑 /etc/resolv.conf，设置dns

nameserver 202.96.134.133

nameserver 202.106.0.20

(3)执行下面两个命令，启用新设置

$sudo ifdown eth0

$sudo ifup eth0
