node.js app on centos access from http://

I have running CentOs and put my app into Default folder.

I can access files through http://myCentOSIP/ and it works.

I can run "$npm start" in bash, and run my node.js application locally. But I can't access that app using http:// request from other computer

I've added in my main "server.js" file:

http.createServer(app).listen(8080);

and it works but only locally.. but still not on others machines

What I need is just simple access my app from other IP outside CentOs using http request

I've also tried:

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(8080, 5050);

where 5050 is my localhost:5050 app prot. And this also failed.
