　　记住网卡名字 eno2(根据实际情况不一致)

root@temple-102:~# cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto eno2
iface eno2 inet static
address 192.168.1.102   
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameserver 8.8.8.8

　　

root@temple-102:~# /etc/init.d/networking restart 
[ ok ] Restarting networking (via systemctl): networking.service.

可能会不生效， 重启电脑生效！
