安装虚拟机时，为了避免每次重启虚拟机IP发生变化，所以进行静态IP的配置
步骤：- 配置静态IP,除了IP外，网关和DNS也需要进行配置
- 查看网关IP Gateway
$ route -n
- 查看DNS IP, nameserver
$ cat /etc/resolv.conf
-
查看当前网络配置(注意要记住网卡名字ens33)
$ ifconfig
- 修改静态IP
$ sudo vim /etc/network/interfaces
旧配置如下（动态IP)
# 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 interfaceauto loiface lo inet loopback# The primary network interfaceauto ens33iface ens33 inet dhcp
修改为新配置(静态IP)，注意Ubuntu 16 使用的网卡命名不是eth + 数字，而是 ens + 数字,所以配置静态IP前请记住ifconfig输出的网卡名称（上面第4步）
# 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 interfaceauto loiface lo inet loopback# The primary network interfaceauto ens33iface ens33 inet staticaddress 192.168.14.139gateway 192.168.14.2netmask 255.255.255.0broadcast 192.168.14.255
-
配置DNS
$ sudo vim /etc/resolvconf/resolv.conf.d/base
首次配置，该文件为空，输入如下内容
nameserver 192.168.14.2
- 刷新DNS配置
$ sudo resolvconf -u
- 重启网卡
$ sudo /etc/init.d/networking restart
- 检查：重复2.3.4三步骤，查看现在的配置，重启虚拟机网络，查看IP是否会发生变化
