Question

我正在运行Redis，Celery 4.0和Django 1.10但在运行任务时遇到[Errrno 61]连接被拒绝错误＆＃39; test＆＃39;来自shell。这是我的项目结构：

myproj
│
├── app1
    ├── __init__.py
    ├── tasks.py
    myproj
    ├── __init__.py
    ├── urls.py
    ├── settings
    │   ├── __init__.py
    │   ├── base.py
    │   ├── local.py
    ├── local
    │   ├── __init__.py
    │   ├── celery.py
    │   ├── wsgi.py

的Myproj / APP1 / tasks.py：

from __future__ import absolute_import
from celery import task

@task(name='app1.tasks.test')
def test():
    print('this is a test')

的Myproj /的Myproj /本地/ celery.py：

from __future__ import absolute_import
import os
from celery import Celery

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproj.settings.local')
app = Celery('myproj_local')

app.config_from_object('django.conf:settings')
app.autodiscover_tasks()

的Myproj /的Myproj /本地/ __init__.py：

from __future__ import absolute_import, unicode_literals
from .celery import app as celery_app
__all__ = ['celery_app']

我认为这个init文件有问题，因为当我将内容移动到myproj / myproj / __init__.py时，任务从shell运行：

from __future__ import absolute_import, unicode_literals

from .local.celery import app as celery_app

__all__ = ['celery_app']

Celery在myproj目录中运行命令：

celery -A myproj.local.celery worker -l info

完整错误：

python manage.py shell --settings=myproj.settings.local

Answer 1

呀！我知道了！我有同样的问题。在文件myproj / app1 / tasks.py中：

from __future__ import absolute_import
from celery import task
app = Celery('myproj_local')
app.config_from_object('django.conf:settings')
@app.task(name='random_name')
def test():
    print('this is a test')

然后，芹菜将在“app”中初始化，配置将被加载到“app”中，您的任务将被延迟。

但只有在您的配置有效时它才会起作用。

Answer 2

您需要将BROKER_URL设置为指向REDIS。

如果您只有一个队列，请确保您的工作人员已连接到默认队列。

如果您在设置中指定了默认队列，则需要将工作人员设置为提取任务，如下所示：

celery -A myproj.local.celery worker -l info -Q queue_name

Django Celery socket.error [Errno 61]连接被拒绝
