Without meaning that in a rude way: Learn to find and read documentation.

Oh and very much avoid random tutorials on the internet. As in, go for official source and use these tutorial only to connect the dots. The reason is that there is huge amounts of really bad advice on the internet and a lot of the tutorials only work in very specific situations (versions, OSs, etc.). Official documentation tends to be a lot better, and it's a good idea to choose software that provides good documentation.

Also make sure you do it one step at a time. You want to give things time to know what failure cases it might have. This prevents you from situations where everything "crashes and burns", because there is an update.
