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

Question

我正在运行Redis，Celery 4.0和Django 1.10，但在从shell运行任务"test"时收到[Errrno 61]连接拒绝错误。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

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')

myproj/myproj/local/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()

myproj/myproj/local/__init__.py：

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

我认为这个初始化文件中有问题，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 正在使用以下命令在 myproj 目录中运行：

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

完整错误：

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

Answer 1

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

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，芹菜会在"app"中初始化，config会在"app"中加载，你的任务就会延迟。

但仅当您的配置有效时，它才会起作用。

Answer 2

您需要将BROKER_URL设置为指向 REDIS。

如果只有一个队列，请确保辅助角色已连接到默认队列。

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取件任务，如下所示：

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