title: Create DB in production environment in rails
body: <p>I have searched for how to create db in production environment for rails and got 2 answers. Now I am confused with those answers.</p>
  
  <pre><code>RAILS_ENV=production rake db:create db:schema:load
  RAILS_ENV=production rake db:create
  </code></pre>
  
  <p>What is the difference between these two? What does this schema means?</p>
  
  <p>Why do we need <code>db:schema:load</code>?</p>
  
  <p>Thanks in advance.</p>
