Hostname can be made permanent with below steps:

  1. Set hostname $ sudo hostnamectl set-hostname new-hostname

$ sudo vi /etc/hosts

Find the localhost string and append the new hostname.

127.0.0.1 localhost webserver.mydomain.com

Save and exit

  1. Confirm the change in hostname:

$ hostnamectl
