人生苦短，我用python。

看到這句話的時(shí)候，感覺可能確實(shí)是很深得人心，不過每每想學(xué)學(xué)，就又止步，年紀(jì)大了，感覺學(xué)什么東西都很慢，很難，精神啊注意力啊思維啊都跟不上。今天奶牛來分享自己今天踩的一個(gè)坑。

先說說配置過程吧，初學(xué)Django，啥都不懂，當(dāng)然，python也很水，啥東西都得現(xiàn)查現(xiàn)用。Django安裝還是很簡單的。

apt-get install python3pip3 install django

嗯，就是兩條命令的事兒。

再說celery的安裝：

pip3 install celerypip3 install redis==2.10.6

目前奶牛所在的時(shí)間redis for python的版本是redis-3.0.1，為什么要用2.10.6呢？因?yàn)?.0.1壓根配置就無法運(yùn)行?。?！

繼續(xù)安裝redis server

apt-get install redisservice redis start

然后就可以按照celery的官方教程走了，放個(gè)URL：http://docs.celeryproject.org/en/latest/django/index.html

python3 manage.py startproject nenewcd nenewpython3 manage.py startapp nenewapptouch ./nenew/celery.pytouch ./nenewapp/tasks.py

然后增加nenew/nenew/celery.py內(nèi)容為

from __future__ import absolute_import, unicode_literalsimport osfrom celery import Celery# set the default Django settings module for the 'celery' program.os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'nenew.settings')app = Celery('nenew')# Using a string here means the worker doesn'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', namespace='CELERY')# Load task modules from all registered Django app configs.app.autodiscover_tasks()@app.task(bind=True)def debug_task(self):  print('Request: {0!r}'.format(self.request))

增加nenew/nenew/__init__.py的內(nèi)容

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',)

增加nenew/nenewtest/tasks.py的內(nèi)容

# Create your tasks herefrom __future__ import absolute_import, unicode_literalsfrom celery import shared_task@shared_taskdef add(x, y):  return x + y@shared_taskdef mul(x, y):  return x * y@shared_taskdef xsum(numbers):  return sum(numbers)

在nenew/nenew/settings.py中增加和修改

...ALLOWED_HOSTS = ['*']....INSTALLED_APPS = [...  'nenewtest',]...CELERY_BROKER_URL = 'redis://localhost:6379/1'CELERY_RESULT_BACKEND = ‘redis://localhost:6379/0'

在nenew/nenewtest/views.py中增加或修改為

from django.shortcuts import renderfrom django.http import HttpResponsefrom .tasks import add# Create your views here.def nenewtest(request):  result = add.delay('2','2')  result.ready()  return HttpResponse('nenew Django Celery worker run !')
