废话不多说直接讲

kakkk@kakkk:~$ cd /etc/netplan/
kakkk@kakkk:/etc/netplan$ ls    #查看配置文件的名字，修改它
00-installer-config.yaml
kakkk@kakkk:/etc/netplan$ sudo vim 00-installer-config.yaml

修改成你需要的配置

# This is the network config written by 'subiquity'
network:
  ethernets:
    ens33:
      dhcp4: false                  # 改成false，关闭dhcp
      # 下面两个配置如果没有，手动输入
      addresses: [192.168.0.13/24]  # IP地址
      gateway4: 192.168.0.1         # 网关
  version: 2

保存（vim怎么保存自己想办法哈哈哈哈）

使新配置生效：

$ sudo netplan apply

查看结果：

搞定，又水一文（只是记录啦，没有专门水的意思）
