To configure a static IP address on your Ubuntu 18.04 server you need to modify a relevant netplan network configuration file within /etc/netplan/
directory.
For example you might find there a default netplan configuration file called 01-netcfg.yaml
or 50-cloud-init.yaml
with a following content instructing the networkd
deamon to configure your network interface via DHCP:
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
ens160:
dhcp4: yes
To set your network interface ens160 to static IP address 192.168.1.10
with gateway 192.168.1.1
and DNS server as 192.168.1.1 replace the above configuration with the one below.
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
ens160:
dhcp4: no
addresses: [192.168.1.10/24]
gateway4: 192.168.1.1
nameservers:
addresses: [192.168.1.1]
Once ready apply changes with:
$ sudo netplan apply
In case you run into some issues execute:
$ sudo netplan --debug apply
