To begin, I'm quite a newbie to Rails. I'm making a blog app, and when trying to run it on production, both ways:

rails s -e production

and

RAILS_ENV=production

I get the same error:

=> Booting WEBrick => Rails 3.2.8 application starting in production on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

/home/loku/.rvm/gems/ruby-1.9.3-p286/gems/activerecord-> resolve_hash_connection': database configuration does not specify adapter (ActiveRecord::AdapterNotSpecified)
...

My setup:

ruby 1.9.3p286 (2012-10-12 revision 37165) [i686-linux]

Rails 3.2.8

database.yml:

development:    
  adapter: mysql2    
  encoding: utf8    
  reconnect: false    
  database: blogg_development    
  pool: 5    
  timeout: 5000    
  username: root    
  password: *** 
  host: localhost    

production:    
  adapter: mysql2       
  encoding: utf8    
  reconnect: false    
  database: blogg_production    
  pool: 5    
  timeout: 5000    
  username: root    
  password: ***
