Redoku在Heroku上拒绝连接 [英] Connection refused for Redis on Heroku

问题描述

我试图在Heroku上设置Redis作为Celery的后端。我有本地工作，但在Heroku，我得到这个错误（芹菜任务完成后）：ConnectionError：错误111连接本地主机：6379。连接被拒绝。

从其他答案中我可以看出，这表明redis服务器不在线，尽管REDISTOGO_URL似乎配置正确。 p>

在settings.py中：

  REDIS_URL = os.getenv（'REDISTOGO_URL '，'redis：// localhost：6379/0'）
  

在tasks.py中：

  from celery import Celery 
 celery = Celery（'tasks'，backend = settings.CELERY_RESULT_BACKEND，broker = settings.REDIS_URL） 
  

版本：

  celery == 3.0.5 
 celery-with-redis == 3.0 
 django-celery == 3.0.4 
 kombu == 2.3.2 
 redis == 2.6.0 
  

解决方案

发现问题。我将芹菜后端配置为字符串'redis'而不是REDIS_URL。

我有：

  CELERY_RESULT_BACKEND ='redis'
  

应该是什么：

  CELERY_RESULT_BACKEND = REDIS_URL 
  

德米特里 - 感谢您的帮助。

I'm trying to set up Redis on Heroku as a backend for Celery. I have it working locally but on Heroku, I get this error (after the celery task completes): ConnectionError: Error 111 connecting localhost:6379. Connection refused.

From what I can tell from other answers, that would indicate that the redis server isn't online, though the REDISTOGO_URL seems to be configured properly.

In settings.py:

REDIS_URL = os.getenv('REDISTOGO_URL', 'redis://localhost:6379/0')

In tasks.py:

from celery import Celery
celery = Celery('tasks', backend=settings.CELERY_RESULT_BACKEND, broker=settings.REDIS_URL)

Versions:

celery==3.0.5
celery-with-redis==3.0
django-celery==3.0.4
kombu==2.3.2
redis==2.6.0

解决方案

Found the problem. I had the celery backend configured to the string 'redis' rather than the REDIS_URL.

What I had:

CELERY_RESULT_BACKEND = 'redis'

What it should be:

CELERY_RESULT_BACKEND = REDIS_URL
