Question

我正在尝试让我的django项目在后台运行定期任务，这就是我所拥有的。

我的celery.py：

from __future__ import absolute_import

import os
from datetime import timedelta
import django

from celery import Celery
from celery.schedules import crontab
from django.conf import settings


CELERY_TIMEZONE = 'UTC'
# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'linker.settings')
django.setup()

app = Celery('linker',
             broker='amqp://',
             backend='amqp://',
             )
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)


CELERYBEAT_SCHEDULE = {
    'add-every-30-seconds': {
        'task': 'distributors.tasks.add',
        'schedule': timedelta(seconds=30),
        'args': (16, 16)
    },

}

tasks.py：

from __future__ import absolute_import

from celery import shared_task


@shared_task
def add(x, y):
    print(x + y)


@shared_task
def mul(x, y):
    return x * y


@shared_task
def xsum(numbers):
    return sum(numbers)


@shared_task
def update_ds(pk):
    pass

当我尝试运行celery -A linker worker -B -l info时，我看到标准的芹菜：

 -------------- celery@ovd v3.1.18 (Cipater)
---- **** ----- 
--- * ***  * -- Linux-3.13.0-55-generic-x86_64-with-Ubuntu-14.04-trusty
-- * - **** --- 
- ** ---------- [config]
- ** ---------- .> app:         linker:0x7f84c73df940
- ** ---------- .> transport:   amqp://guest:**@localhost:5672//
- ** ---------- .> results:     amqp://
- *** --- * --- .> concurrency: 4 (prefork)
-- ******* ---- 
--- ***** ----- [queues]
 -------------- .> celery           exchange=celery(direct) key=celery

但我没有看到任何结果或至少发生过程。

使这项工作成功并将打印信息启用到控制台的方法是什么？

Django定期任务不起作用
