title: Configure Celery to talk to Redis via Unix socket
body: <p>I would like Celery to build on Redis rather than the default RabbitMQ.</p>
  <p>The <a href="http://docs.celeryproject.org/en/latest/getting-started/brokers/redis.html" rel="noreferrer">Celery documentation</a> explains:</p>
  <blockquote>
  <p>Configuration is easy, just configure the location of your Redis database:</p>
  <p><code>BROKER_URL = 'redis://localhost:6379/0'</code></p>
  <p>Where the URL is in the format of:</p>
  <p><code>redis://:password@hostname:port/db_number</code></p>
  <p>all fields after the scheme are optional, and will default to localhost on port 6379, using database 0.</p>
  </blockquote>
  <p>However, I have Redis set up NOT to listen to a port, but instead to listen to a socket.</p>
  <p>Is there a URI scheme to support this?</p>
