Setup Hostname
Log into the hostname (ssh)
Run the following command
sudo hostnamectl set-hostname NewHostName
Also need to update the hosts name
sudo vi /etc/hosts
Example of old host file
127.0.0.1 localhost
127.0.1.1 old-hostname.vocus.co.nz old-hostname
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
Example of updated host
127.0.0.1 localhost
127.0.1.1 New-hostname.vocus.co.nz New-hostname
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
While hostnamectl typically applies the changes immediately, some services or applications might still be referencing the old hostname. You can restart network services or reboot the system for a complete refresh, although often it's not strictly necessary. To restart network services:
sudo systemctl restart network-online.target
or just reboot
Sudo Reboot
