This article Reference article: https://linuxize.com/post/how-to-configure-static-ip-address-on-ubuntu-18-04/

First, view the card name ip address

Second, edit netplan network management tools

sudo vi /etc/netplan/01-network-manager-all.yaml 
#Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager
  ethernets:
    ens3:
        dhcp4: no
        dhcp6: no 
        addresses: [192.168.0.222/24]                  #配置网卡IP
        gateway4: 192.168.0.1                              #配置网关
        nameservers:
            addresses: [114.114.114.114, 8.8.8.8]   #配置DNS

*温馨提示：编辑yaml文件时需严格按照格式来，空格不能使用Tab键缩进，每个冒号后边均有一个空格。*

Use the following commands to configure the application

sudo netplan --debug apply           #加--debug参数可以显示报错信息，进行调试
