ubuntu设置静态ip

1. modify /etc/networks/interfaces as follow.

****************************************************************************************

auto lo
iface lo inet loopback
#net card eth0 configuration
auto eth0
iface eth0 inet static
#set static ip
address 192.168.1.108
netmask 255.255.255.0
gateway 192.168.1.1
#dns-nameservers 8.8.8.8
#network 192.168.1.0
#boardcast 192.168.1.255

****************************************************************************************

2. modify /etc/resolvconf/resolv.conf.d/head as follow.

****************************************************************************************

nameserver 202.96.128.86

****************************************************************************************

the below 3 lines was ok before:

search mydomain.com
nameserver 61.139.39.73
nameserver 61.139.2.69

3. sudo resolvconf -u

after this command, the contents of /etc/resolv.conf is the same as /etc/resolvconf/resolv.conf.d/head.

4. sudo /etc/init.d/networking restart

5. modify /etc/resolv.conf as follow if it not changed after network restarted

****************************************************************************************
nameserver 202.96.128.86

****************************************************************************************

notice:

1. if the ip showed in ifconfig result not corresponding to the one in /etc/network/interfaces after sudo /etc/init.d/networking restart, try the below solution:

$ sudo ifdown eth0;sudo ifup eth0

2. if Ubuntu can't connect to network, it may be nameserver is not proper, and try a new nameserver.
