linux系统设置静态IP，DHCP网络服务，DNS

一、设置静态IP及DHCP网络服务

kk@yuanqiangfei:~$ cat /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                                                #eth0网卡开机启动

iface eth0 inet dhcp                                 　　 #使用DHCP服务器申请动态IP

#iface eth0 inet static                             　　  #设置eth0网卡静态IP

#address 192.168.1.188                        　　　　　　 #静态IP

#netmask 255.255.255.0                       　　　　　　  #掩码

#gateway 192.168.1.1                           　　　　　  #网关

二、修改DNS

kk@yuanqiangfei:~$ cat /etc/resolvconf/resolv.conf.d/base

nameserver 192.168.3.1

nameserver 192.168.1.1

kk@yuanqiangfei:~$ ^C

kk@yuanqiangfei:~$ resolvconf -u

查看修改是否成功：　

修改相关参数之后重启网络：

sudo service networking restart
