listen EADDRNOTAVAIL error in Node.js

Question

I installed Nginx and Node.js in my server.

When I try run my node.js file, I get an error:

node.js:201
        throw e; // process.nextTick error, or \'e         


        

Answer 1

var express = require('express');

var app = express();
app.set('port', process.env.PORT || 3000);
app.set('host', process.env.HOST || 'localhost');

app.listen(app.get('port'), function(){
  console.log('Express server listening on port ' + app.get('host') + ':' + app.get('port'));
});

works for me.
it also generic for debug by localhost and your local ip without any changes.
