For this new year, I’d like to learn the skills necessary to self host. Specifically, I would like to eventually be able to self host Nextcloud, Jellyfin and possibly my email server too.
I’ve have a basic level understanding of Python and Kotlin. Now I’m in the process of learning Linux through a virtual machine because I know Linux is better suited for self hosting.
Should I stick with Python? Or is JavaScript (or maybe Ruby) better suited for that purpose? I’m more than happy to learn a new language, but I’m unsure on which is better suited.
And if you could start again in your self hosting journey, what would you do differently? :)
EDIT: I wasn’t expecting all these wonderful replies. You’re all very kind people to share so much with me :)
The consensus seems to be that hosting your own email server might be a lot, so I might leave that as future project. But for Nextcloud and Jellyfin I saw a lot of great tips! I forgot to mention that ideally I would like to have Nextcloud available for multiple users (ie. family memebers) so indeed learning some basic networking/firewalling seems the bare minimum.
I also promise that I will carefully read the manuals!
Basic networking knowledge is vital. And being able to configure your own firewall(s) safely is an important skill. Check out something like Foomuuri, or Firewald. Shorewall is brilliant for documentation and description of issues (with diagrams!) but it does not use the newer Linux kernel nftables and is no longer actively developed.
Go for it with Nextcloud.
I would also recommend at least having a shot at setting up an email server, although I would recommend pushing through to a fully working system. It is possible, and is very satisfying to have in place. The process of setting one up touches so many different parts of internet function and culture that it is worth it even if you don’t end up with a production system. The Workaround.org ISPMail stuff is a good starting point, and includes some helpful background information at every stage, enough so you can begin to understand what’s going on in the background and why certain choices are being made - even if you disagree with the decisions.
Python is great for server admin, although most server config and startup shutdown snippets are written in BASH. You will no doubt have already begun picking that up as you interact with your VMs.

Experimenting with VMs is the way forward.
