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-20122 iface eth0 inet static3 address 192.168.196.135 #change to your static IP4 netmask 255.255.255.0 #change to your netmask5 gateway 192.168.196.255 #change to your getway6 #We must specify dns-nameserver here7 #in order to get internet access from host8 dns-nameservers 192.168.196.2559 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 loiface lo inet loopback#add by andy at 2014-08-14# Assgin static IP by eric on 26-SEP-2012iface eth0 inet staticaddress 192.168.196.135 #change to your static IPnetmask 255.255.255.0 #change to your netmaskgateway 192.168.196.255 #change to your getway#We must specify dns-nameserver here#in order to get internet access from hostdns-nameservers 192.168.196.255auto 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 .cn PING (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。
