As title says, i want to start self hosting but i have a lot of questions about it. For more context, i want to self host XMPP, matrix, Immich, an email, forgejo and a minimal website. i want to ask you:
-
Where should i buy my domain and are there any things i should be careful about?
-
does the end of my domain (idk the specific name but .XYZ) matter at all?
-
I get that i should use a used PC (i have none lying around), but how old?
-
Am i willing to self host too much stuff?
-
Can i use Gentoo, Devuan, or other non-systemd distros as an OS?
Sorry for the noob questions but i struggle to find answers online, feel free to tell me to RTFM _;
Also, i have experience with Linux as a desktop OS, more specifically 3 years, one of which mostly in gentoo, but i’ve daily driven Arch, Artix, Debian, Void among others


not sure. i host at home and vpn in with tailscale
shouldnt matter i believe?
depends on what youre doing, but for simple file sharing and some small automations you could probably get away with a 10ish year old computer. i used a 2012 hp pc for many years. only replaced it abt a year ago.
if your machine can handle it, who cares?
you can use anything you like. host everything on plan9 for all i care.
