title: Rails : rake db:create mysql error
body: <p>I am trying to setup a mysql database, but I am getting this error message:</p>
  
  <pre>
  rake db:create
  (in /Users/yookd/Desktop/rails/blog)

  <p>Any assistance with this?

  <p><strong>EDIT:::</strong></p>
  
  <p>How can I use mysql as my database as opposed to sqlite?  In the gemfile, it explicitly states: <code>gem 'sqlite'</code>... do I need to replace that line with something like <code>gem mysql</code>?</p>
