ubuntu 设置静态IP

##设置IP地址、网关
cp /etc/network/interfaces  /etc/network/interfacesbak   #备份原有配置文件
vim /etc/network/interfaces   #编辑网网卡配置文件

auto lo
auto eth0 
iface lo inet loopback
iface eth0 inet static
address 192.168.21.166
netmask 255.255.255.0
gateway 192.168.21.2
dns-nameservers 192.168.20.20 

  

直接修改/etc/resolv.conf 重启后可能会清空

vim /etc/resolvconf/resolv.conf.d/base

nameserver 192.168.20.20
nameserver 114.114.114.114

sudo resolvconf -u  #使配置生效
