title: How can I open my custom URL-s?
body: <p>I'm trying to get my homework done in Ruby on Rails, but I have already faced dozens of problems because of my lack of UBUNTU (16.04.1) knowledge.</p>
  
  <p>I have installed all the required gems and other clients like MySQL2, Apache2 and Puma. Puma is running, I have two standard tables in MySQL, but there is some issue with my Apache2 connection. I can access localhost:3000 (it says: Yay! You are on rails now!), but I just cannot reach my custom URL-s, that are located in the 'hosts' file.</p>
  
  <p>Could any of you help me with getting started? I could blow my top because I have a lot of work to do and I cannot get through the basic steps of installing the environment...</p>
  
  <p>Thanks in advance!</p>
