Ubuntu 16.04网络配置（静态IP）

打开虚拟机编辑/etc/network/interfaces文件

root@swift:/home/swift# cat /etc/network/interfaces

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface

auto lo

iface lo inet loopback

# The primary network interface

auto ens33#16.04的命名为ens33不是eth0

iface ens33 inet static#static表示静态

address 192.168.110.111    #IP地址

netmask 255.255.255.0    #子网掩码

gateway 192.168.110.2    #网关

dns-nameservers 61.139.2.69    #DNS

root@swift:/home/swift# /etc/init.d/networking restart

[ ok ] Restarting networking (via systemctl): networking.service.

到此配置完成可以连接网络进行安装和更新了。

如果重启服务后还是不能连接网络

编辑/etc/resolvconf/resolv.conf.d/目录下的base  head两个文件

在末尾追加DNS

例如：

nameserver 61.139.2.69#使用当地网络服务商提供的DNS

修改后重启网络服务或重启虚拟机（reboot、init 6、shutdown -r now等多种方法）。
