Ubuntu 20.04 sets a static IP address (including different versions)
|
Because Ubuntu 20.04 manages the network through netplan, which is slightly different from previous versions, Ubuntu 18.04 seems to need to edit /network/interfaces to set up a static network Because it is a virtual machine, I first change it to bridge mode
Next edit the file: sudo vim /etc/netplan/01-network-manager-all.yaml Modify the file content to: I have always wondered whether I need to make modifications for different IP addresses? But since I haven't reached that level yet, I'm not very clear about it. It should be modifiable. But there is no problem typing the following code directly into the file
Enter: wq to save and exit, then enter sudo netplan --debug apply You can
Now the static IP is set up, and you can view the current IP address through ifconfig. 12.x Version $ cat /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 20.20.20.102 netmask 255.255.255.0 gateway 20.20.20.102 dns-nameservers 20.20.20.2 14.x Version $ cat /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 20.20.20.102 netmask 255.255.255.0 gateway 20.20.20.102 dns-nameservers 20.20.20.2 $ cat /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile,ofono dns=dnsmasq no-auto-default=00:0C:29:D7:43:29, [ifupdown] managed=true 16.x version $ cat /etc/network/interfaces auto lo iface lo inet loopback auto ens32 iface ens32 inet static address 20.20.20.102 netmask 255.255.255.0 gateway 20.20.20.102 $ cat /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile,ofono dns=dnsmasq no-auto-default=00:0C:29:D7:43:29, [ifupdown] managed=true $ cat /etc/resolv.conf nameserver 127.0.1.1 nameserver 20.20.20.2 18.x version: 1. First check the network card name $ ip a /ifconfig 2. cp a yaml file and change its name $ sudo cp /etc/netplan/*.yaml /etc/netplan/network card name.yaml 3. Modify the contents of the yaml file as follows: # Let NetworkManager manage all devices on this system network: version: 2 renderer: NetworkManager ethernets: Network card name: dhcp4: no addresses: [ip/prefix] gateway4: gateway nameservers: addresses: [dns] 4. Start $ sudo netplan apply 5. Verification $ ip a /ifconfig This is the end of this article about setting a static IP address for Ubuntu 20.04 (including different versions).
