Ubuntu20.4靜態ip和dhcp配置

一、目錄及配置文件：

cd /etc/netplan
vim 01-network-manager-all.yaml

二、靜態ip配置方式：

01-network-manager-all.yaml.static

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager
  ethernets:
    enp4s0:
      dhcp4: false
      addresses: [192.168.100.87/24]
      gateway4: 192.168.100.3
      nameservers:
        addresses: [192.168.100.3,8.8.8.8]

三、DHCP配置方式：

01-network-manager-all.yaml.dhcp

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager
  ethernets:
    enp4s0:
      dhcp4: true

四、重啟netplan：

需要啟用哪一種ip分配策略就拷貝文件，並去掉最后的后綴

cp 01-network-manager-all.yaml.xxxx 01-network-manager-all.yaml
sudo netplan --debug apply
ip a
