Ubuntu网路配置

1.修改/etc/network/interfaces

nano /etc/network/interfaces加入以下内容

# The primary network interface

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet static

address 192.168.1.100

gateway 192.168.1.1

netmask 255.255.255.0

dns-nameservers 8.8.8.8

2. 打开配置文件sudo vi /etc/resolv.conf

nameserver 8.8.8.8

nameserver 8.8.4.4

nameserver 192.168.40.1

domain localdomain

search localdomain

3.修改完毕后重启网络：sudo  /etc/init.d/networking restart

发现问题ubuntu10.04必须写回环配置，否则开机mysql起不来，ubuntu12.04不写下面两句话也可以

auto lo

iface lo inet loopback
