错误：Node.js中的Econn被拒绝

Question

I'm going through a RabbitMQ tutorial in node.js

Every time I run node send.js I keep getting an error saying the econn is refused.

Here's what my code looks like:

var amqp = require('amqplib');
var when = require('when');

amqp.connect('amqp://localhost').then(function(conn){
        return when (conn.createChannel().then(function(ch){
                var q = 'hello';
                var msg= 'Hello World!';

                var ok = ch.assertQueue(q, {durable: false});

                return ok.then(function(_qok){
                        ch.sendToQueue(q, new Buffer(msg));
                        console.log(" [x] Sent '%s'",msg);
                        return ch.close();
                });
        })).ensure(function() {conn.close(); });;
}).then(null,console.warn);

Here's what the error says:

  { [Error: connect ECONNREFUSED]
  code: 'ECONNREFUSED',
  errno: 'ECONNREFUSED',
  syscall: 'connect' }

I'm not sure what I'm doing wrong, or what I need (I'm not too experienced with node.js). But I'm pretty sure it has something to do with the localhost server. I tried googling and searching on here at stackoverflow, but nothing that I could find to my use.

You need to start RabbitMQ-server before connecting. If you installed RabbitMQ as a system package in Linux, issue:

sudo service rabbitmq-server start

If you downloaded and unpacked it somewhere (any OS), then launch the rabbitmq-server script you will found in the sbin/ subdirectory.

If you did not download the server, then get the appropriate package from RabbitMQ download page .
