Ubuntu 18.04 Server - Set Static IP With Netplan
Netplan is the new networking system that is taking over from editing the /etc/networking/interfaces file. The most common thing you will want to do is set a static IP. You can do that by simply editing the /etc/netplan/01-netcfg.yaml file.
sudo vim /etc/netplan/01-netcfg.yaml
The file will look like below:
# This file describes the network interfaces available on your system # For more information, see netplan(5). network: version: 2 renderer: networkd ethernets: ens2: dhcp4: yes
Here is an example configuration to set a static IP of 192.168.1.100 with your router/gateway being at 192.168.1.1 and wanting to use OpenDNS dns servers:
# This file describes the network interfaces available on your system # For more information, see netplan(5). network: version: 2 renderer: networkd ethernets: ens2: addresses: - 192.168.1.100/24 gateway4: 192.168.1.1 nameservers: addresses: - 18.104.22.168 - 22.214.171.124
Before I could paste, I had to fix an "issue" with vim first with the following commands:
echo "set mouse=" > .vimrc sudo echo "set mouse=" | sudo tee -a /root/.vimrc Ubuntu Blog - Ubuntu Bionic: Netplan
Once you have successfully edited your configuration file, you can apply it with:
sudo netplan apply
Now your server should be using the new IP.
Netplan is actually pretty powerful and you can split your configuration up across multiple files in multiple locations as well as configuring bridges/bonding etc. I recommend reading these two posts for more information:
