Rails Server crashing upon running getting "no such file or directory"

Question

I recently cloned a github repo and i'm trying to get it to work on my mac. I cloned it, did bundle install and got all the gems installed. When I try to do "rails server" I get an error:

=> Booting Mongrel
=> Rails 3.0.1 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

What can I do to fix this problem? I don't have a database.yml, which is the issue. However, neither did the repo when I cloned it. Why is it looking for a file that wasn't suppose to be there to begin with?

Answer 1

When people push their repo on github, they exclude configuration files from that repo. You'll need to create a database.yml file in order to make your application work.

Here's an example of it.

development:
  adapter: mysql
  database: bibapp_development
  username: root
  password: 

test:
  adapter: mysql
  database: bibapp_test
  username: root
  password:

production:
  adapter: mysql
  database: bibapp_production
  username: root
  password:
