If wondered if you can shorten the command you use when you ssh to the same machine all the time.

Well, you can pre-configure these settings in a configuration file and have it reference that when you are SSHing into a machine.

That way you can just SSH using this shorter command: $ ssh master

Instead of the long command: $ ssh username@ipaddressofmachine -i location/of/ssh/key/file

Here's how you do it.

I will show you how to install Gitlab onto your own Linux server (also known as self-managed Gitlab server). For my example, I will be installing Gitlab on my Linux server running Centos 8 and will activate HTTPS on it.
