I know how to set up ghost to run at http://abcxyz.com, and i have a reverse proxy thru nginx that reads ghost running at 2368.

however, i want ghost as a subroute/subdirectory on my page, in the form of http://abcxyz.com/blog, and not as the main page. I have a node application that serves as my original site (the part that is http://abcxyz.com), but I can't figure out how to link the blog as the subdirectory. How do I do this?
