ubuntu配置静态ip不起作用，解决

ubuntu@ubuntu:~$ cat /etc/netplan/01-netcfg.yaml
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
     dhcp4: yes
     dhcp6: no
ubuntu@ubuntu:~$

查看dhcp为yes，手动通过网口改ip没起作用
改为如下：
ubuntu@ubuntu:~$ cat /etc/netplan/01-netcfg.yaml
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
     dhcp4: no
     dhcp6: no
     addresses: [172.16.4.161/24]
     gateway4: 172.16.4.1
     nameservers:
             addresses: [114.114.114.114]
ubuntu@ubuntu:~$
然后调用
netplan apply
即可
