I am completely new to the realm of self hosting. I don’t know a single thing about how I can self host stuff. Regardless, I have the curiousity to learn it by myself but I don’t know where to start. I cannot find any sort of wiki or FAQ articles, nor do I have the ability to ask the forum for every single problem or doubt I encounter during the setup. Can someone direct me to a beginner friendly site that teaches all there is about self hosting and all the questions and misconceptions that come with it?
Additionally, is a self hosted server only accessible inside my home? What about accessing the services outside, like Bitwarden or Nextcloud apps that require syncing and availability of data wherever I am? If it is useless outside, there would be no point for me personally to self host in the first place since I am perfectly fine with using cloud services for now and the convenience that comes with it. Plus, no one else in my family cares about self hosting and I don’t wish to spend the effort to convince them to in vain, so setting up a server for convenience of everyone at home is also out of the question.
There’s no guide thats covers everything, because the possibilities are nearly endless.
The first step is to get a server and choose an OS. You can build your own server at home or you can rent a VPS.
If you rent a VPS your services will be accessible from everywhere. If you decide to get a homeserver everything will be only accessible at your local network. You can acces your services from outside through VPN or port forwading.
When your server is ready, you can start to host your services. Just look at the documentation of the project e.g. on github.
