Ubuntu20.04 set static IP

Note: Ubuntu 20.04 sets static IP through netplan

step:

1. Check the name of the network card ( this machine uses ens33 )

Command: ip a

2. Generally speaking, if a file is modified, a copy of the file will be saved first

sudo cp /etc/netplan/01-network-manager-all.yaml 01-network-manager-all.yaml.bak

3. Edit 01-network-manager-all.yaml (you can also use vi vim to modify)

sudo nano /etc/netplan/01-network-manager-all.yaml

4. Enter the following information

network:
version: 2
renderer: NetworkManager
ethernets:
 ens33:
  dhcp4: no
  addresses:
  - 192.168.72.140/24
  gateway4: 192.168.72.2
  nameservers:
   addresses: [8.8.8.8, 8.8.4.4]

Note: Be sure to pay attention to the indentation, otherwise the configuration will not succeed

Note: The gateway4 gateway is set to the gateway of the network cable

5. Enable configuration

sudo netplan apply

6. Finish, check it through ip a by yourself
