win10下实现django+celery定时任务

系统环境：win10
python版本3.7
django    # 我默认使用的最新版本 根据自己的需求
celery==4.3.0
django_celery==3.3.1
django_celery_beat==2.1.0
eventlet        # 根据需求使用版本 我用的是默认的最新版本

项目结构目录

#config.py-------配置broker，result-backend,序列化等相关
#celery.py-------程序的入口文件
#__init__.py------告诉python这是一个包
#tasks.py----------任务文件

celery.py内容

from __future__ import absolute_import

from celery import Celery
#app是Celery类的实例，创建的时候添加了proj.tasks这个模块，也就是包含了proj/tasks.py这个文件
app = Celery('proj',include=['proj.tasks'])

#另一种配置方式，这里就大概写一下
#app = Celery('任务名',broker='xxx',backend='xxx',include=['xxx','xxx'])

#去找配置文件
app.config_from_object('proj.config')

config.py

from __future__ import absolute_import
#使用redis作为消息代理
BROKER_URL = 'redis://127.0.0.1:6379/1'
#把任务结果存放在redis2号库
CELERY_RESULT_BACKEND = 'redis://127.0.0.1:6379/2'

##以下内容可以不用配置，这些都是默认配置，除非自定义需要配置,我用 -- 框住
# -------------------------------------------------
#任务序列化和反序列化使用msgpack方案
CELERY_TASK_SERIALIZER = 'msgpack'

#读取任务结果一般性能要求不高，所以使用了可读性更好的JSON
CELERY_RESULT_SERIALIZER = 'json'

#任务过期时间，不建议直接写86400，应该让这样的magic数字表述更明显
CELERY_TASK_RESULT_EXPIRES = 60*60*24

#指定接受的内容类型
CELERY_ACCEPT_CONTENT = ['json','msgpack']

# --------------------------------------------------


#定时任务配置
from datetime import timedelta
CELERY_TIMEZONE = 'Asia/Shanghai'
CELERY_ENABLE_UTC=True

#ps：友情提示 CELERYBEAT_SCHEDULE 千万不要写错了，我之前写成 CELERY_BEAT_SCHEDULE导致定时任务执行不了，惨痛的教训！！！

CELERYBEAT_SCHEDULE = {
    #这个名字(print_test)随便写，无所谓
    'print_test': {
        'task': 'proj.tasks.print_test',      #绑定的定时任务的函数
        'schedule': timedelta(seconds=2),      #设置定时时间，这里是2秒执行一次
         'args':()       #用来给函数传参

    }
}

tasks.py

from __future__ import absolute_import

from .celery import app


@app.task
def print_test():
    print("nict try")
    return 'hello'

我们就可以来做一个测试了

启动worker (# 执行celery 时要在proj的父目录，这里是apps)

celery worker -A proj -l info -P eventlet

启动定时任务的发送方： (# 执行celery 时要在proj的父目录，这里是apps)

celery beat -A proj
