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:
This will work on kubuntu as well. My tutorial shows how to use
