Answer 1

You didn't provide much information. First things first, ssh to your open shift application and check the node log file.

cd $OPENSHIFT_LOG_DIR

Also make sure you are using

process.env.OPENSHIFT_NODEJS_PORT

and

process.env.OPENSHIFT_NODEJS_IP

when you set your application's ip and port properties.

Answer 2

You must use env of openshift:

create server.js in root folder:

#!/usr/bin/env node

var express = require('express');
var http = require('http');
var app = express();

// define some router here
.......

var ip = process.env.OPENSHIFT_NODEJS_PORT || 3000;
var port = process.env.OPENSHIFT_NODEJS_IP || '127.0.0.1';

app.set('port', port);

var server = http.createServer(app);
server.listen(port, ip);

create file .gitignore enter node_modules

Use git update your code.

git add .
git commit -m "First upload project"
git push
