Apache2 + ISPConfig + Ruby on Rails

Hi

I’m trying to get ruby running on a Debian Linux server with ISPConfig
and Apache.

I have tried many tutorials like:

  1. http://www.howtoforge.com/ruby_on_rails_apache2_fastcgi_debian_p6

http://www.howtoforge.de/howto/verwendung-von-ruby-on-rails-mit-apache2-auf-debian-etch/
3.
http://www.howtoforge.de/howto/linux/wie-man-mod_ruby-fur-die-verwendung-mit-ispconfig-2220-und-neuere-versionen-auf-verschiedenen-linux-distributionen-installiert/

the ruby projekt is at var/www/web1/

the public folder is renamed into web (the apache root folder)

If I connect to a *.rb file in var/www/web1/web/test.rb everything works
out.

But if i connect to var/www/web/app/views/bla via
http://www.domain.xy/bla I get an webserver Error 503 (timeout)

What could be the reason for that?

Greetings Andi
