Change the envirument.rb file, to enable production mode. (remove the  
comment out of ENV production line)

Please note when running migrtation, you need to use:  
rake db:migrate RAILS\_ENV=“production” (for usage of the correct  
database)

You should have written unit tests for your app, as you developed it.  
‘rake  
test’ runs in test mode, and it depends on the test: key in your  
database.yml  
file, and your config/environments/test.rb file.

Run your server in development mode with one of these:

RAILS\_ENV=production script/server  
script/server -e production
