title: create new application ruby on rails
body: <p>I'm bit confused by "easy" working with ruby on rails, cause I already spend three days by trying create an app.</p>
  
  <p>I work on site5 hosting, and try to create new app. step by step:</p>
  
  <pre><code>$ rails new app -d mysql
  
  $ gem install mysql
  
  $ gem install mysql2
  </code></pre>
  
  <p>and after</p>
  
  <pre><code>$ rake db:create
  </code></pre>
  
  <p>it report about error</p>
  
  <p><code>Could not find gem 'mysql2 (~&gt; 0.2.6, runtime)' in any of the gem sources listed in your Gemfile.</code></p>
  
  <p>I google it, but still can't fix problem. Can anybody help?</p>
