Question

我的django应用程序有两项任务，其中一项是定期任务。

正常任务：AddScore 定期任务：CalculateTopScore

class CalculateTopScore(celery.Task):

    default_retry_delay = settings.DEFAULT_RETRY_DELAY
    max_retries = settings.DEFAULT_MAX_RETRIES
    name = 'games.tasks.CalculateTopScore'

    def run(self):
        try:
            # Code to run

        except Exception, err:
            logger.exception("Error in running task calculate_top_score")
            self.retry(exc=err)

        return True

    def on_failure(self, exc, task_id):

        failure = "%s task for calculate_top_score failed permanently." % task_id
        logger.error(failure)

    def on_success(self):

        task_info = 'calculate_top_score task successfully'
        logger.info(task_info)

我想每30分钟定期执行一次这个任务。

以下是我正在使用的设置：

#celery/settings.py

import djcelery
import kombu

from celery.schedules import crontab
from config.celery import exchanges


djcelery.setup_loader()

CELERYBEAT_SCHEDULER = "djcelery.schedulers.DatabaseScheduler"

CELERYBEAT_SCHEDULE = {
    "calcluate_score": {
        "task": "games.tasks.CalculateTopScore",
        "schedule": crontab(minute='*/30'),
        "args": (),
    },
}

CELERY_QUEUES = (
    kombu.Queue('add_score',
                exchange=exchanges.add_score_exchange,
                routing_key='add.scores'),
    kombu.Queue('calcluate_score',
                 exchange=exchanges.calcluate_score_exchange,
                 routing_key='calculate.scores'),
)

CELERY_ROUTES = ('config.celery.routers.CeleryTaskRouter',)

# Default delay(in seconds) for retrying tasks.
DEFAULT_RETRY_DELAY = 60

# Maximum retry count
DEFAULT_MAX_RETRIES = 6

CELERY_IGNORE_RESULT = True

exchanges.py文件

#exchanges.py

from kombu import Exchange

add_score_exchange = Exchange('add_score', type='direct')
calcluate_score_exchange = Exchange('calcluate_score', type='direct')

routes.py文件

ROUTES = {
    'players.tasks.AddScore': {
        'exchange': 'add_score',
        'exchange_type': 'direct',
        'routing_key': 'add.score',
    },
   'games.tasks.CalculateTopScore': {
        'exchange': 'calculate_score',
        'exchange_type': 'direct',
        'routing_key': 'calculate.score',
    },
}


class CeleryTaskRouter(object):
    """ This is a basic celery task router.
    """

    def route_for_task(self, task, arg=None, kwargs=None):
        return ROUTES.get(task)

在我们的生产服务器上，我使用以下参数运行celeryd：celeryd worker -B

现在在日志中我观察到celerybeat每30分钟安排一次任务，但是工作人员根本不知道计划的任务，因此没有执行任务。

为什么呢？任何配置/设置丢失？如何定期执行基于类的任务？

请帮忙

您可能必须指定希望芹菜从中获取任务的队列。默认是使用celery队列。

尝试：

celeryd worker -B -Q add_score,calculate_score

芹菜调度任务定期但不执行它们
