定时任务框架Djcelery 即django+celery框架搭建以及Redis服务及启动，报错解决

   参考  https://blog.youkuaiyun.com/michael_lbs/article/details/74923367

   1.安装  pyramid_celery-3.0.0   https://pypi.python.org/pypi/pyramid_celery/

           pip install pyramid_celery

   2.安装  django-celery-3.2.2   https://pypi.python.org/pypi/django-celery/

           pip install django-celery

 

           Django中设置

           INSTALLED_APPS = ['djcelery',]

python manage.py migrate

   3.安装celery-with-redis-3.0    https://pypi.python.org/pypi/celery-with-redis/

       pip install celery-with-redis

4.安装django-celery-beat-1.1.0    https://pypi.python.org/pypi/django-celery-beat/

       pip install django_celery_beat

    5.下载 Redis-x64-3.2.100.zip文件   https://github.com/MicrosoftArchive/redis/releases 

 

1. Redis服务启动

  一、

  import djcelery
djcelery.setup_loader()   # 加载djcelery
# 数据库调度
CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler'
BROKER_URL = 'redis://127.0.0.1:6379/0'
BROKER_TRANSPORT = 'redis'

二、

Apitest目录下新建celery.py 文件

from __future__ import absolute_import
import os, django
from celery import Celery
from django.conf import settings

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'autotest.settings')
django.setup()

app = Celery('autotest')
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

三、

Apitest目录下新建task.py文件

# -*- coding: utf-8 -*-
import requests, time, sys, re
import urllib, zlib#,
import pymysql
import unittest
from trace import CoverageResults
import json
from idlelib.rpc import response_queue
from apitest.celery import app
from time import sleep
@app.task
def hello_world():
    print('已运行')

 

四、

1. 启动服务 python manage.py runserver
2. 切换到Redis文件夹下  cmd 启动指令   redis-server redis.windows.conf
3. 启动指令 python manage.py celery worker -l info
4. 启动指令 python manage.py celery beat

 

启动指令 python manage.py celery worker -l info报错

TypeError: can only concatenate tuple (not "NoneType") to tuple

 

解决办法：

D:\Python36\Lib\site-packages\djcelery\management\commands\celery.py

文件的14--16行代码注释掉

class Command(CeleryCommand):
    """The celery command."""
    help = 'celery commands, see celery help'
#    options = (CeleryCommand.options +
#               base.get_options() +
#               base.preload_options)

 

class Command(CeleryCommand):
    """The celery command."""
    help = 'celery commands, see celery help'
#    options = (CeleryCommand.options +
#               base.get_options() +
#               base.preload_options)

 

 

 

 

          pip install pyramid_celery
