如何在Ubuntu中设置Node.js应用服务器

Question

I don't understand why i have this problem which i show the output in the second part. While following the tutorial "how To Set Up a Node.js Application for Production on Ubuntu 14.04" i did everything.

I created a script to test my private ip address like this

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

The problem that i encountered while testing the apllication.

JoeDoe@myUbuntu:~$ node hello.js
Server running at http://myPrivateIp:8080/
events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: listen EADDRNOTAVAIL myPrivateIp:8080

Answer 1

The second argument of listen is not the domain name, is the address to listen on. It could be something like 192.168.xx or 127.0.0.1 or 0.0.0.0 ( means all address. ). The default is 127.0.0.1 .

Which means you should remove the second argument of listen .
