I'm thinking of making a website or a server or something, but then I go on here and only understand 6/7 of the stuff here.
Well, what kind of server are you after making? HTTP, game server, storage?My first recommendation, get an old PC and pick a linux distro.I use usually Fedora (Even though I hate systemd), but Ubuntu or Debian could also be good. Or if you're a masochist you could start on FreeBSD, or OpenBSD.

just disable password auth and you're indestructible
Step one: Get an old computer, or (If you have a pretty good computer) get VirtualBox.
