how can integrate apache2 with ruby on rails ?

I use kubuntu.
How can i install ruby on rails in kubuntu?
is ruby on rails integrated with apache2? how can i do?
can anyone give me brief step by step suitable installation procedure
for my configuration(kubuntu+apache2) ?

I've got a tutorial on installing Rails on ubuntu dapper server here:
http://blog.wilf.me.uk/articles/2006/11/20/the-ultimate-server-ruby-on-rails-with-lighttpd-apache2-with-php-mysql-postgresql-on-ubuntu-dapper-server
This will work on kubuntu as well. My tutorial shows how to use
lighttpd for rails while keeping apache2 around for other sites - this
solution may or may not fit your needs but you should find most of the
article relevant.
