cannot get nodejs working on amazon ec2 instance

Question

I am trying to run nodejs server on amazon micro instance for the past 3-4 days with no success.

i followed so many tutorials and i cannot make the server work (so when its visited in browser or curl in powerShell and see the simple hello world).

Here are the last 3 tutorials I've tried:

http://iconof.com/blog/how-to-install-setup-node-js-on-amazon-aws-ec2-complete-guide/ http://techprd.com/setup-node-js-web-server-on-amazon-ec2/ http://devblog.daniel.gs/2014/01/deploying-node-apps-on-aws-ec2-with.html

I've tried ubuntu/ amazon linux.

I've also followed http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-LAMP.html just to see how the general process works and it did work fine.

I get to the point where i do something like: sudo node filename.js and the server runs.

However when i try visiting or curl it. it doesnt work. when i ping it it pings fine.

in amazon i set the security group to basically allow everything like so:

in linux its self i followed : https://help.ubuntu.com/community/IptablesHowTo?action=show&redirect=Iptables to open the port i was trying to listen to and nothing.

when i type : sudo service iptables status i get :

1 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:1337:1347

2 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:1338:1348

3 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:10000

keep in mind i am not a server savvy guy.

Any help would be highly appreciated.

UPDATE: To start my node server i use the basic code found in nodejs.org :

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');

This is exactly how my file look like

You haven't provided enough info, but I'll try and outline the general troubleshooting techniques.

• Is your node program running and serving requests? Get on the Ec2 box and do curl -v localhost:8000 (or whatever your node port is.) It should spit out your app. If not, your node.js setup isn't right.

• Is your nginx running? Get on the box and type curl -v localhost. That will look on your port 80. If it doesn't proxy to your app, it's probably an nginx configuration problem.

• Can you reach the box via IP address? From your desktop/laptop, do curl -v x.x.x.x where x.x.x.x is your EC2 Public IP address. If that hangs, there is a firewall problem.

• Can you reach the box via your DNS? (Assuming you are trying to have foo.com point to it) Try curl -v http://foo.com/. If that doesn't work, your DNS may not be correct.

However when i try visiting or curl it. it doesnt work.

Please be more specific.
