This page lists some advice and guidelines which every YunoHost administrator should be aware to take care of a YunoHost server :)
To put it another way: your server is either a production server (meant to work) or a test server on which you allow yourself to experiment.
If your goal is to run a production server:
YunoHost is designed to work with general and simple use cases in mind. Deviating from those conditions will make things harder and you will need technical knowledge to make it work. For instance,
Keep things as simple as you can!
Some people tend to fall into "the reinstallation spiral" - where each time something breaks in the server and it is not obvious how to fix it, or because the server became "dirty", one ends up reinstalling the whole server from scratch because it looks like an "easy" and quick solution to clean the table.
Please don't do this. Reinstalling is a heavy operation and is not a good long-term strategy for fixing problems. You will get tired and won't learn anything. Forget the dream of having a "clean" server. A real-life server always end up being a bit "dirty". Also, you need to (progressively) learn how to solve issues when you encounter them. Reach for help with detailed symptoms of what you are trying to do and what is happening, and fix the issues. Over time, you will get a much better control over your server than just blindly reinstalling every time.
If you host services and data that are important for your users, it is important that you setup a backup policy. Backups can be easily created from the webadmin - though they currently cannot be downloaded from it (but it can be downloaded through other means). You should perform backup regularly and keep them in a safe and different physical location from your server. More info on the backup documentation.
As an administrator, you should configure an email client to check emails sent to
firstname.lastname@example.org (which should be an alias to the first user your added) or otherwise forward them to another address that you actively check. Those mails may contain information on what is happening on your server such as automated periodic tasks.
Finally, keep in mind that YunoHost is a free software maintained by volunteers - and that the goal of YunoHost (to democratize self-hosting) is not an easy one! It is provided without any warranty. The team of volunteers does its best to maintain and provide the best possible experience - yet features, applications and YunoHost as a whole are far from being perfect and you will experience small and big shortcomings at some points. When this happens, kindly reach for help on the chat or forum, or report the issue! :)
If you like YunoHost and want to see the project being kept alive and make progress, feel free to leave a thank you note and to donate to the project and talk about it around you!
Last but not least, since YunoHost is a free software project, you are legitimate and welcomed to come and contribute to the project, be it on the technical aspects (i.e. code) and less-technical aspects (such as contributing to this documentation! ;))
