Running with pm2 on ec2, need advice

[jordanbaucke]

So after giving up on running my app on Heroku or Openshift due to errors: #796 & #766

I've been working on deploying on ec2 w/ and running behind an NGINX proxy - using a fork of: https://github.com/bevacqua/grunt-ec2

I've got most of the rsync reconfigured to copy just the /dist folder and do all the linking, etc. but when I run pm2 start /srv/apps/ec2/current/server/app.js (https://github.com/Unitech/pm2) or node /server/app.js I get:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: connect EACCES
    at errnoException (net.js:904:11)
    at Object.afterConnect [as oncomplete] (net.js:895:19)

Assuming this is an issue with the port or the ip address that is getting set in the configuration? I want the server to listen on 127.0.0.1:9000 for the proxy.

I can start the app by just copying it to my instance, and running grunt serve:dist so I no it's not a conflict, etc.

Any advice on how I can configure the config and call the commands to appropriately start the server in production mode?
