title: Connecting to redis using kue always creates a connection to localhost
body: <p>I can't connect to Redis using kue, I've followed this <a href="http://bl.ocks.org/mojodna/1251812" rel="noreferrer">article</a>, practically I'm creating the connection by using the kue redis client, and the connection code is this:</p>
  
  <pre><code>  var kue = require('kue'),
    redis = require('kue/node_modules/redis');
  
    app.redisClient =  redis.createClient('6379', 'remoteip',{});
    app.redisClient.on('error', function (err) {
        console.log('Redis error encountered', err);
    });
  
    app.redisClient.on('end', function() {
        console.log('Redis connection closed');
     });
  
     kue.redis.createClient = function() {
        console.log('client ------------------',app.redisClient);
        return app.redisClient;
     };
  </code></pre>
  
  <p>and it seems like Kue is trying to connect to a local Redis (which I don't have installed), because I'm getting this exception:</p>
  
  <blockquote>
    <p>Error: Redis connection to 127.0.0.1:6379 failed - connect
    ECONNREFUSED</p>
  </blockquote>
  
  <p>I've read this <a href="https://github.com/LearnBoost/kue/issues/54" rel="noreferrer">post</a> and it seems like the issue has been resolved in version 0.8 and I'm using 0.8.11 :/,  finally I also wanted to override the client using a different client instance by using <a href="https://github.com/mranney/node_redis" rel="noreferrer">redis nodejs</a> without any luck, because I'm getting the same error.</p>
  
  <p>any help will be more than appreciated.
  thanks!</p>
