Install problem with mysql

Hello. I am new to this stuff and i have some problem. I have winxp, apache2triad and i downloaded the ruby installer for windows. I followed the tutorial in http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html?page=1
without re-installing mysql as i already have it. I created an empty rails application, i did the "ruby script\server" and i show the intro page. I also managed to create a controller. The problem is with the mysql. First of all i didn't see any test database. Moreover i created a database and i then go to the database.yml to see it.
I saw "# MySQL (default setup). Versions 4.1 and 5.0 are recommended." . I expected to see something like
development:
adapter:
database: etc
If i place the code by myself and try to restart the webserver i get a message:

Any idea?

Please post the database.yml you used. Normally it should look like:

Code:

development:
  adapter: mysql
  database: example_dev
  username: ruby
  password: secret123
  host: localhost 

test:
  adapter: mysql
  database: example_test
  username: ruby
  password: secret123
  host: localhost

production:
  development

Also, you need to check if you have installed the ruby-databasedriver for mysql. The default database.yml contains a hint:

Code:

# Install the MySQL driver:
#   gem install mysql
# On MacOS X:
#   gem install mysql -- --include=/usr/local/lib
# On Windows:
#   There is no gem for Windows.  Install mysql.so from RubyForApache.
#   http://rubyforge.org/projects/rubyforapache

bye,
grande
