I am somewhat late into the Linux-verse (three years in now) and want to move into self-hosting to do two things:
-
Host my own Jitsi server and sessions. (or any other open source solution)
-
Host my own solution to privately and securely share photographs of my kids and life here with my family abroad.
At some point, I want to host my own little static-website about myself which should “replace” having to give people a LinkedIn account or something.
The thing is, I know nothing about owning domains, etc. I have never done this before. I have been lurking around this forum to learn some of the basics, but would really like a more tailored reply (is possible). I am working in Europe.
-
Which computer should I use? I want to host everything on my computer at home. I don’t want to go the VPS route.
-
Where can I buy an inexpensive domain(s)? I assume I only need one.
-
What other things do I need to consider? My current broadband is IPv4 only.
I have used Piwigo for this purpose the past 3.5 years. It’s running on a tiny Odroid HC-2 and solid state drive. The same device also runs Emby for video streaming. I started it with a free sub domain from afraid.org. I migrated to a real domain later. To run two services from one domain name you also need a reverse proxy and SSL certificate renewal, like SWAG or NGINX Proxy Manager or Zoraxy.
The main thing I’ve learned is keeping everything isolated repeatable. On my Odroid I learned to use Docker and Portainer for the apps. But there were a couple times I broke everything through updates/upgrades. Now I have a small Intel N305 (Minsforum UN305C), running ProxMox VE, and apps in Linux containers. The first I set up myself to learn but later I discovered some open source helper scripts https://tteck.github.io/Proxmox/. ProxMox seems a bit more complex than Docker/Portainer, but more flexible.
I’m using IPv4 only but I’m migrating to IPv6 soon to help with in-network routing to my domain. My advice would be unless you want to host your own DNS and override your domain to resolve to LAN, just use your IP:port on LAN and use the domain only outside your home.
