如果你想删除所有挂起的任务，以及活动和保留的任务，以完全停止Celery，这对我来说是有效的:

from proj.celery import app
from celery.task.control import inspect, revoke

# remove pending tasks
app.control.purge()

# remove active tasks
i = inspect()
jobs = i.active()
for hostname in jobs:
    tasks = jobs[hostname]
    for task in tasks:
        revoke(task['id'], terminate=True)

# remove reserved tasks
jobs = i.reserved()
for hostname in jobs:
    tasks = jobs[hostname]
    for task in tasks:
        revoke(task['id'], terminate=True)

对于芹菜5.0+版本，使用RabbitMQ作为代理

我们需要先建立一个从程序到经纪人的新连接， 并将连接与要清除的队列绑定。

# proj/celery.py
from celery import Celery
app = Celery('proj')

from proj.celery import app
queues = ['queue_A', 'queue_B', 'queue_C']
with app.connection_for_write() as conn:
    conn.connect()
    for queue in queues:
        count = app.amqp.queues[queue].bind(conn).purge()
        print(f'Purge {queue} with {count} message(s)')

对于芹菜3.0+:

$ celery purge

清除特定队列:

$ celery -Q queue_name purge

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。

芹菜3+:

CLI:

$ celery -A proj purge

编程:

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