1.配置静态IPsudo vi /etc/network/interfaces# The primary network interfaceauto enp0s3 #enp0s3为当前系统的网卡

1.配置静态IP

sudo vi /etc/network/interfaces

# The primary network interfaceauto enp0s3    #enp0s3为当前系统的网卡#iface enp0s3 inet dhcp  #注释掉dhcp#如下添加静态IP信息iface enp0s3 inet staticaddress 192.168.0.2gateway 192.168.0.1netmask 255.255.255.0network 192.168.0.0broadcast 192.168.0.255

2.配置DNS

方式一：
resolv.conf是一个链接文件，所以系统重启后dns配置会失效

sudo vim /etc/resolv.conf

nameserver 202.96.199.133

方式二：在 /etc/network/interfaces配置，重启后不会失效

dns-nameserver 219.141.136.10 219.141.140.10

方式三：修改resolv.conf链接的文件，重启后不会失效

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

nameserver 219.141.136.10 219.141.140.10

3.重启服务

sudo service networking restart

或者

sudo /etc/init.d/networking restart
