Question

I am new to rail 3. Can I directly go changing the database.yml and… what?

Answer 1

Change your database.yml to look something like this:

development:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: <database name>
  pool: 5
  username: <user name>
  password: <password>
  host: <host>

Then, just run rake db:schema:load to have it create your tables. Then test!
