ror 3 + apache2 + passenger = apache test page

I set up Passenger on manual -
http://wiki.rubyonrails.org/deployment/apache-passenger

Passenger and Apache install without errors.

/etc/httpd/conf/httpd.conf:

...
LoadModule passenger_module
/usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.2/
ext/apache2/mod_passenger.so
PassengerRoot /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.2
PassengerRuby /usr/local/bin/ruby
PassengerDefaultUser root
...
<VirtualHost *:80>
   ServerName 39pk.ru
   ServerAlias www.39pk.ru
   DocumentRoot /var/www/rails/zak
   RailsEnv production
   RailsBaseURI /app
   ErrorLog logs/39pk.ru.log
</VirtualHost>
...

rails_app/config/enviroment.rb:

require File.expand_path('../application', __FILE__)
   Zak::Application.initialize!
Rails::Initializer.run do |config|
    config.action_controller.relative_url_root = '/app' # add this
end

# pwd
/var/www/rails/
# ls -la
итого 8

Apache starts successfully, but instead of pages of ROR3, I see apache
testpage. But apache see all files, which in public ROR directory -
/home/up/rails3/zak/public
What i must do to normaly run Rails?

Check your permissions, i have had similar problem before and they usually have to do we the permission of the user:group apache runs with.

all rights to all files are 0777, i tried all the users in the
user:group in httpd.conf. It did not help.

DocumentRoot /var/www/rails/zak

this should point to the public directory, no to the app directory
