redis不能在我的python django應用程序中工作

Question

我首先在heroku網站上跟着教程。我這樣做

pip install rq 

然後在worker.py文件

import os 

    import redis 
    from rq import Worker, Queue, Connection 

    listen = ['high', 'default', 'low'] 

    redis_url = os.getenv('REDISTOGO_URL', 'redis://localhost:6379') 

    conn = redis.from_url(redis_url) 

    if __name__ == '__main__': 
     with Connection(conn): 
      worker = Worker(map(Queue, listen)) 
      worker.work() 

然後

python worker.py 

，我得到了以下錯誤

     raise ConnectionError(self._error_message(e)) 
    redis.exceptions.ConnectionError: Error 61 connecting to localhost:6379. Connection refused. 

然後我去了谷歌，並找到了我也包的指數其次是

>>> import redis 
>>> r = redis.StrictRedis(host='localhost', port=6379, db=0) 
>>> r.set('foo', 'bar') 

回車，得到了以下信息

我沒有做過或多或少的又是什麼，這些教程問。我該如何做這項工作？

Answer 1

您需要運行redis服務器。在控制檯上鍵入redis-server以啓動服務器（Mac OSX）。

$redis-server 

請記住，工作人員需要代理（redis）才能與您的應用進行通信。
