对于芹菜5.0+，从CLI执行该操作，并针对特定的队列:

—APP_NAME清除——QUEUE_NAME

如果你想像我一样在一个步骤中做，那么在最后添加-f选项来跳过确认步骤。

从文档中可以看出:

$ celery -A proj purge

or

from proj.celery import app
app.control.purge()

(编辑:更新与当前的方法。)

1. 要正确清除等待任务的队列，您必须停止所有的worker (http://celery.readthedocs.io/en/latest/faq.html#i-ve-purged-messages-but-there-are-still-messages-left-in-the-queue):

$ sudo rabbitmqctl stop

或者(如果RabbitMQ/消息代理由Supervisor管理):

$ sudo supervisorctl stop all

2. .．.然后清除特定队列中的任务:

$ cd <source_dir>
$ celery amqp queue.purge <queue name>

3. RabbitMQ开始:

$ sudo rabbitmqctl start

或者(如果RabbitMQ由Supervisor管理):

$ sudo supervisorctl start all

CLI:

$ celery -A proj purge

编程:

>>> from proj.celery import app
>>> app.control.purge()

芹菜2。X和3.x:

例如，当使用带-Q参数的worker来定义队列时

celery worker -Q queue1,queue2,queue3

然后芹菜清除将不会工作，因为您不能传递队列参数给它。它只会删除默认队列。 解决方案是用——purge参数启动你的worker，就像这样:

celery worker -Q queue1,queue2,queue3 --purge

然而，这将运行worker。

另一个选择是使用芹菜的amqp子命令

celery amqp queue.delete queue1
celery amqp queue.delete queue2
celery amqp queue.delete queue3

CLI

清除命名队列:

 celery -A proj amqp queue.purge <queue name>

清除配置的队列

celery -A proj purge

I’ve purged messages, but there are still messages left in the queue? Answer: Tasks are acknowledged (removed from the queue) as soon as they are actually executed. After the worker has received a task, it will take some time until it is actually executed, especially if there are a lot of tasks already waiting for execution. Messages that are not acknowledged are held on to by the worker until it closes the connection to the broker (AMQP server). When that connection is closed (e.g. because the worker was stopped) the tasks will be re-sent by the broker to the next available worker (or the same worker when it has been restarted), so to properly purge the queue of waiting tasks you have to stop all the workers, and then purge the tasks using celery.control.purge().

因此，要清除整个队列，必须停止worker。
