开发环境

系统：win10
python: 2.7.12
django: 1.9.8

安装

pip install django-celery 

创建项目和APP

django-admin.py createproject dc_test
django-admin.py startapp demo

编辑settings.py

BROKER_URL = 'django://localhost:8000//'
CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler'
CELERY_TIMEZONE = 'Asia/Shanghai'

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'kombu.transport.django',
    'demo',
    'djcelery',
]

TIME_ZONE = 'Asia/Shanghai'

编辑settings.py同级目录的init.py

from __future__ import absolute_import, unicode_literals

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app

__all__ = ['celery_app']

在settings.py同级目录新建celery.py

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', 'dc_test.settings')

app = Celery('dc_test')

# 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))

在APP目录下新建tasks.py

from __future__ import absolute_import, unicode_literals
from celery import shared_task

@shared_task
def hello_world():
    with open("output.txt", "a") as f:
        f.write("hello world")
        f.write("\n")

创建数据表并创建超级用户

python manage.py makemigrations
python manage.py migrate
python manage.py createsuperuser

登陆后台并配置定时任务

1）python manage.py runserver
2) 访问127.0.0.1:8000/admin
3) 设置为每5秒钟执行一次task

启动celery worker(接收任务)

python manage.py celery worker -l info

启动celery beat（发送任务）

python manage.py celery beat

效果

每隔5秒，往文件output.txt，写入hello world
