it asks for libmysql.dll

Go to your mysql/bin  
and copy paste libmysql.dll to ruby/bin  
after that restart your webrick or ruby server.

Check first what is your mysql server run? if your mysql is ok. then  
check your config/database.yml

check all configuration there :

development:  
adapter: mysql  
database: database\_name  
username: root  
password: my\_password  
host: localhost

You should ensure that all login information to database mysql is  
correct.

Good Luck,

your configuration is correct, what is your problem right now?

IF you can reach [http://127.0.0.1:3000/](http://127.0.0.1:3000/) successfully, it means that your  
rails is successfully connected to database.

If you have problem in loading page you should check your controller and  
corresponding method.

Example:

class SuperHeroController \< ApplicationController

def index  
#index page business logic here  
end

def listing  
#listing page business logic here  
end

end

so that your url will be [http://127.0.0.1:3000/super\_hero/listing](http://127.0.0.1:3000/super_hero/listing)

if you want [http://127.0.0.1:3000/](http://127.0.0.1:3000/) redirect to your main page you should  
do modification at app\_name/config/route.rb:

ActionController::Routing::Routes.draw do |map|  
map.connect ‘’, :controller =\> “super\_hero”

…

end

don’t forget to delete index.rhtml or index.html.erb in app\_name/public/
