在 Elastic Beanstalk 上创建环境时出现 502

502 occurs when creating environment on elastic beanstalk

我在部署我的第一个 Django 项目时遇到问题。

这是我的 config.yml:

global:
  application_name: testapp
  branch: null
  default_ec2_keyname: aws-eb
  default_platform: Python 3.8 running on 64bit Amazon Linux 2
  default_region: us-west-2
  include_git_submodules: true
  instance_profile: null
  platform_name: null
  platform_version: null
  profile: eb-cli
  repository: null
  sc: null
  workspace_type: Application

这是我的 django.config:

option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: djangoproject.wsgi:application

我关注了this doc。但是在我做了 eb create testapp-env 之后,我得到了 502 错误: image of the error

如果您需要,我会提供更多信息。预先感谢您的帮助。

这是 web.stdout.log 中的错误:

django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

更新

我的 django 项目使用 python-socketio,这是我的 wsgi.py:

from django.core.wsgi import get_wsgi_application
import socketio
from post.socketioserver import sio # <- it's just my socket io code

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'djangoproject.settings')

django_app = get_wsgi_application()
application = socketio.WSGIApp(sio, django_app)

我收到另一个错误:

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

您需要设置DJANGO_SETTINGS_MODULE环境变量:

option_settings:
   aws:elasticbeanstalk:container:python:
      WSGIPath: djangoproject.wsgi:application
   aws:elasticbeanstalk:application:environment:
      DJANGO_SETTINGS_MODULE: "djangoproject.settings"

您还需要编辑 wsgi.py 文件,因为您在 Django 设置之前访问应用程序:

import django
django.setup()

from django.core.wsgi import get_wsgi_application
import socketio
from post.socketioserver import sio # <- it's just my socket io code

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'djangoproject.settings')

django_app = get_wsgi_application()
application = socketio.WSGIApp(sio, django_app)
