ubuntu 设置静态IP的实现方法

ubuntu 设定静态ip：

切换到root用户，然后进入/etc/network目录。备份interfaces文件(备份文件是一个好习惯)

下面编辑interfaces文件，添加如下语句：

1 # assgin static ip by eric on 26-sep-2012
2 iface eth0 inet static
3 address 192.168.196.135     #change to your static ip
4 netmask 255.255.255.0      #change to your netmask
5 gateway 192.168.196.255     #change to your getway
6 #we must specify dns-nameserver here
7 #in order to get internet access from host
8 dns-nameservers 192.168.196.255
9 auto eth0

编辑完成后的interfaces文件内容如下：

root@ubuntu:/etc/network# cat interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

#add by andy at 2014-08-14
# assgin static ip by eric on 26-sep-2012
iface eth0 inet static
address 192.168.196.135     #change to your static ip
netmask 255.255.255.0      #change to your netmask
gateway 192.168.196.255     #change to your getway
#we must specify dns-nameserver here
#in order to get internet access from host
dns-nameservers 192.168.196.255
auto eth0

下一步就是重启网卡：

root@ubuntu:/etc/network# /etc/init.d/networking restart
重启完成后，测试一下：

 root@ubuntu:/etc/network# ping www.baidu.com.cn
 ping www.a.shifen.com (220.181.112.244) 56(84) bytes of data.
 64 bytes from 220.181.112.244: icmp_req=1 ttl=128 time=6.12 ms
 64 bytes from 220.181.112.244: icmp_req=2 ttl=128 time=14.7 ms

ok。静态ip设置完成。
