title: Deploy MySQL database on Heroku with Ruby on Rails
body: <p>I am trying to deploy a Rails project on Heroku. My Rails application uses <code>mysql2</code>.</p>
  
  <p>I have tried using the <code>taps</code> gem but its not working. I get the following error when I run the command <code>taps server mysql://root@localhost/heroku_ex tempuser tempass</code>:</p>
  
  <blockquote>
    <p>Failed to connect to database: Sequel::AdapterNotFound -> LoadError: cannot load such file -- mysql</p>
  </blockquote>
  
  <p>Is there any way to deploy my application on Heroku? I would prefer to only use free add-ons if possible.</p>
