Question

运行celery status或celery purge命令时遇到问题。

 File "/usr/bin/celery", line 11, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/site-packages/celery/__main__.py", line 30, in main
    main()

    return self.execute(command, argv)

  File "/usr/lib/python2.7/site-packages/amqp/transport.py", line 95, in __init__
    raise socket.error(last_err)
socket.error: [Errno 111] Connection refused

我正在使用SQS BROKER_URL。任务运行正常，但是当我想清除队列上的任务（celery purge -f）时，我得到上述错误。

software -> celery:3.1.11 (Cipater) kombu:3.0.18 py:2.7.5
            billiard:3.3.0.17 py-amqp:1.4.5
platform -> system:Linux arch:64bit, ELF imp:CPython
loader   -> celery.loaders.default.Loader
settings -> transport:amqp results:disabled

我的服务器端口22,80,443,8000端口打开，SQS celery队列中有大量消息，因此芹菜和SQS之间的连接应该没问题。

基于documentation of the commands status and purge，你需要提供芹菜与你所指的芹菜应用程序，以便它知道要使用的经纪人。只需输入$celery purge或输入$celery status芹菜，我就不知道您定位的芹菜应用程序是什么，因此失败。

因此，请转到您的芹菜应用程序

$cd /path/to/your/celery/app/directory

然后在您的应用上调用celery purge。在此示例中，我的目录为celeryapp.py，内容为：

from config import config
from celery import Celery
celery_app = Celery('tasks', 
                    backend=config.celery_backend_uri, 
                    broker=config.celery_broker_uri)
celery_app.conf.update(
    CELERY_IMPORTS=(
        'app.module_a.tasks',   # we're not including our tasks here as
        'app.module_b.tasks',   # our tasks are in other files listed here
    )
)

内容并不像我们的电话那么重要，但提供这些内容是为了表明我们在celeryapp.py内有我们的芹菜应用程序，因此我可以致电

$celery -A celeryapp status
worker-name-a@node-name: OK
worker-name-b@node-name: OK

或

$celery -A celeryapp purge
WARNING: This will remove all tasks from queue: celery.
         There is no undo for this operation! 
(to skip this prompt use the -f option)
Are you sure you want to delete all tasks (yes/NO)? yes
No messages purged from 1 queue

我有一个类似的question here，如果没有通过陈述提供应用程序，Sol似乎确认芹菜会输出此错误

如果你没有给它提供应用程序的位置，它将如何知道要使用的经纪人运输？

使用带有SQS的Celery时，Errno 111连接被拒绝
