Rails-app at root.com;how to move to root.com/dir/

I’ve managed to get my rails app up and running when navigating to http://www.root.com/. I’d like it to only be able to be accessed when going to http://www.root.com/dir/ (basically put it in a subdir).

I would think this should be super easy but can’t seem to figure it out.

Can someone point me to the appropriate change I need to make in cpanel?
