2. Start a small project, perhaps a computer of interest to you. games, then play out various typical scenarios (eg migration to another server (new OS + web + database)). In scenarios, take into account the key indicators for you - the integrity and availability of information, and this is immediately fault tolerance, backups, DDoS protection, etc.
This will be a real "combat" experience.

From the beginning, understand what they are for, install them, and for questions they will disappear by themselves. You can't get far on bare theory, theory + practice = knowledge => work and experience.

Now host a couple of websites there and make them work on different versions of php!
