# what now?  Add init.d script and config files for nginx 

# you want to run a node socket IO demo?
# check out this:  https://github.com/mmukhin/psitsmike_example_1

These 3 scripts should get you well on your way to making your own debian server build with MongoDB and node with nginx and socket.io support. All on one box. Works well with rackspace. From zero to socket.io capable instance in about a half hour.
