Question

我尝试在redis中获取所有活动/预定/预留任务：

from celery.task.control import inspect
inspect_obj = inspect()
inspect_obj.active()
inspect_obj.scheduled()
inspect_obj.reserved()

但是受到如下错误列表的欢迎：我的虚拟环境==＆gt; HubblerAPI。我在ec2控制台上使用它

Traceback (most recent call last):

**OSError: [Errno 111] Connection refused**

我的芹菜配置文件如下：

BROKER_TRANSPORT = 'redis'
BROKER_TRANSPORT_OPTIONS = {
    'queue_name_prefix': 'dev-',
    'wait_time_seconds': 10,
    'polling_interval': 30,
    # The polling interval decides the number of seconds to sleep 
      between unsuccessful polls
    'visibility_timeout': 3600 * 5,
    # If a task is not acknowledged within the visibility_timeout, the 
      task will be redelivered to another worker and executed.
}
CELERY_MESSAGES_DB = 6
BROKER_URL = "redis://%s:%s/%s" % (AWS_REDIS_ENDPOINT, AWS_REDIS_PORT, 
              CELERY_MESSAGES_DB)

我在这里做错了，因为错误日志表明它没有使用redis代理。

Answer 1

看起来你的python代码无法识别你的配置，因为它试图使用RabbitMQ的ampq协议而不是配置的代理。

我建议如下

http://docs.celeryproject.org/en/latest/getting-started/brokers/redis.html

您的配置看起来类似于Celery的Django配置，但它似乎并没有使用Celery与Django。

http://docs.celeryproject.org/en/latest/django/first-steps-with-django.html#using-celery-with-django

Answer 2

问题是在settings.py中使用“ BROKER_URL”而不是“ CELERY_BROKER_URL”。 Celery找不到URL，并且默认使用Rabbitmq端口而不是redis端口。

错误111连接被拒绝（Python，芹菜，redis）
