Django，Celery Supervisor：密钥错误：django.core.exceptions.ImproperlyConfigured：SECRET_KEY 设置不能为空

Question

我有一个 django 1.11.4、python3.5、gunicorn 19.7.1 服务器和主管、redis 2.10.6 和 celery 4.1.0。

我的文件结构是这样的：

samy_python
├── celery.py
├── __init__.py
├── settings
├── urls.py
├── wsgi.py
website
├── static
├── templates
├── samy
|    ├── samy_firebase.py
|    ├── tasks.py
├── views.py

我得到了我的秘密：

# settings.py
SECRET_KEY = os.environ.get("secret_KEY")

我的 celery 主管配置文件是：

[program:gunicorn]

....
environment = secret_KEY="12345"
.....

[program:celery]
directory=/home/username/Projects/samy/samy_python
command=/home/username/Projects/samy/samy_python/env/bin/celery --app=samy_python.celery.app worker -B -l info
user=username
stdout_logfile=/var/log/celery/celery.log
stderr_logfile=/var/log/celery/celery.log
autostart=false
autorestart=false
startsecs=10

我的芹菜档案：

# celery.py

from __future__ import absolute_import
import os
import logging
logger = logging.getLogger('myapp.celery.py')

from celery import Celery
from django.conf import settings

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "samy_python.settings")

# Celery App
# TODO
# [START Celery App]
app = Celery('samy_python')
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

# [END Celery App]

我的初始化文件：

# __init__.py

from __future__ import absolute_import
from .celery import app as celery_app

我的 celery 的 settings.py 文件中的配置：

BROKER_URL = 'redis://localhost:6379/1'
CELERY_RESULT_BACKEND = 'redis://localhost:6379/1'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'

错误可能来自我的 settings.py 文件，我使用 env 变量来设置环境。 （生产、开发或测试）：

DEBUG = False
DJANGO_TESTING = False
DJANGO_DEVELOPMENT = False
DJANGO_ENV = os.environ.get('DJANGO_ENV')

if DJANGO_ENV == 'DJANGO_TESTING':
    DJANGO_TESTING = True
elif DJANGO_ENV == 'DJANGO_DEVELOPMENT':
    DJANGO_DEVELOPMENT = True

然后我设置 firebase 凭据和 Google Api 凭据。然后我从内部获取凭据，例如 samy_firebase.py：

from django.conf import settings
if settings.DJANGO_TESTING == True:
    logger.info('Firebase Config: Test DB')

我不确定最后一部分是否相关，但这是我不断收到的错误：

   Traceback (most recent call last):

    return obj.__dict__[self.__name__]
KeyError: 'data'

During handling of the above exception, another exception occurred:

django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

另外，gunicorn 工作得很好，所以如果我不启动 celery 程序，它会接收环境变量。此外，如果我在 settings.py 文件中将密钥设置为“12345”，它就会启动。

Answer 1

像这样在 env 中设置 secret_KEY：

export SECRET_KEY="#mysecret_key"

然后检查：

echo $SECRET_KEY

在您的 django 设置中，更改为：

SECRET_KEY = os.environ.get("SECRET_KEY")

详细参考检查：Read and Set Environment Variables

Answer 2

将环境变量添加到主管配置文件的[program:celery] 部分。目前只为gunicorn设置。
