我有一个Django应用程序,我想对其进行配置以运行后台任务。
包装:
芹菜== 4.2.1
Django == 2.1.3
Python == 3.5
Redis-server == 3.0.6
settings.py 文件中的芹菜配置为:
?
和 celery.py 文件:
CELERY_BROKER_URL = 'redis://localhost:6379'
CELERY_RESULT_BACKEND = 'redis://localhost:6379'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TASK_SERIALIZER = 'json'
CELERY_TIMEZONE = 'Asia/Kolkata'
CELERY_BEAT_SCHEDULE = {
'task-number-one': {
'task': 'app.tasks.task_number_one',
'schedule': crontab(minute='*/1'),
},
}
我跑步时:from __future__ import absolute_import, unicode_literals
import os
from celery import Celery
from django.conf import settings
# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings.prod')
app = Celery('project')
# Using a string here means the worker don't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
# should have a `CELERY_` prefix.
app.config_from_object('django.conf:settings')
# Load task modules from all registered Django app configs.
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)
@app.task(bind=True)
def debug_task(self):
print('Request: {0!r}'.format(self.request))
它指向rabmmitmq服务器,而应该指向redis-server,如下所示:
celery -A project worker -l info -B -E
在生产环境中也发生了同样的情况。
在生产环境中,我已经将Gunicorn和Nginx的Django应用程序部署了,现在我想实现一些方法来运行后台任务,因为 -------------- celery@user-desktop v4.2.1 (windowlicker)

包不起作用。
问题:
芹菜配置有什么问题?
谁能推荐一种运行定期后台任务的方法?
**注意:我已经尝试实现超级用户,但是超级用户似乎与python3不兼容,因此无法对其进行配置。

broker url changed in v4的设置。它应该是BROKER_URL
,而不是CELERY_BROKER_URL
。

替换
CELERY_BROKER_URL = 'redis://localhost:6379'
与
BROKER_URL = 'redis://localhost:6379'
。这对我有用。

如果您已从celery官方网站celery.py
复制了https://docs.celeryproject.org/en/latest/django/first-steps-with-django.html
的内容
尝试更改以下行,从
app.config_from_object('django.conf:settings', namespace='CELERY')
到
app.config_from_object('django.conf:settings', namespace='')
