Hi all,
To change the hostname of your server, you’ll need to follow 4 quick and easy steps. Let’s begin:
Enter your Droplet
Firstly, you’ll need to SSH to your Droplet with either root or a sudo user. You can do that using the command
Another way would be using the droplet’s console from your Control Panel with DigitalOcean.

In the case it’s installed, you’ll need to edit it as well. Open the file,
Find the line
and change it to be
Save the file and exit.
That’s it, you are ready now!!
To make sure everything is working properly, execute the command
