Question install Rails app in subdirectory?

[sweetp]

Hey guys,

I am wanting to install a Ruby on Rails app in a subdirectory of my domain, but don't see a way to achieve this through the UI?

I can install the app just fine, and I have it configured in the envioronment.rb file to run on the subdirectory:
mydomain.com/store
and this works great, but.... the app also runs on the root domain:
mydomain.com

well, technically it doesnt run, it just throws an error. but thats what it should do.

what i really want is my static site to run on the root domain:
mydomain.com
and the rails app running on
mydomain.com/store


i also want to run a wordpress blog and a mybb forum: mydomain.com/blog, mydomain.com/support... but first the rails app. I had this setup all happily running on a cpanel server, before i migrated over to Plesk.


could someone please walk me through what i need to do to get this running.

thanks in advance.
