Posted on Sunday March 13, 2016 by Eric Potvin
The hostname uniquely identifies your computer on the local network. The hostname can be use in many services or applications. Once the hostname is set, it is not recommended to change it.
To setup the hostname run this command:
echo "choose_a_better_hostname" > /etc/hostname hostname -F /etc/hostname
Now, let's set the hostname in the host file.
sudo vi /etc/hosts
and Add the IP address(es) and the the hostname:
127.0.0.1 localhost.localdomain localhost 18.104.22.168 choose_a_better_hostname.domain.com choose_a_better_hostname
