The command you run is perfectly fine.

It's your configuration files (config/database.yml) that are missing the correct settings for the production environment though.

To start server in production mode type : 

RAILS_ENV=production rails s

in the console.

Here is my output for this: 

=> Booting Thin
=> Rails 4.1.0 application starting in production on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server
>> Thin web server (v1.5.1 codename Straight Razor)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:3000, CTRL+C to stop

as you can see in the second line it is in production.

Be aware that RAILS_ENV is case sensitive.

Seems like you are getting error because your credentials are incorrect, not because your RAILS_ENV is production...

Several things can cause this behaviour.

  1. Double check if you created your database for production ENV.
  2. Check credentials you use for connection on database.
  3. Your mySQL server is not running.
