title: Remote mysql database on Heroku app
body: <p>Can I use mysql database from my personal web server instead of heroku's database?</p>
  
  <p>I configured my production database like this:</p>
  
  <pre><code>production:
      adapter: mysql2
      database: somedatabase
      username: someusername
      password: somepassword
      host: 1.1.1.1:1234
  </code></pre>
  
  <p>But, this doesn't work, my app still uses heroku's shared database.</p>
