Ruby on Rails + Michael Hartl tutorial + VPS = issues with AWS

I have finished Michael Hartl tutorial and I'm trying to deploy it with http://ift.tt/19KZkHg. Unfortunately I'm stuck with RAILS_ENV=production rake db:migrate because it's generating following error:

ArgumentError: Missing required arguments: aws_access_key_id, aws_secret_access_key

/home/me/simpleapp/config/initializers/carrier_wave.rb:3:in `block in <top (required)>'

/home/me/simpleapp/config/initializers/carrier_wave.rb:2:in `<top (required)>'

/home/me/simpleapp/config/environment.rb:5:in `<top (required)>

'

I have even copied those files 1:1 and still this error persists. Any idea how could I solve it? I really am tired with trying to fix it with different solutions from web. Thanks
