将 Django 应用程序部署到 Elastic Beanstalk AWS 502 错误网关

Question

我按照 AWS 官方网站上的所有说明进行操作，但仍然遇到同样的错误。 我已经尝试了几个项目，本地服务器上的每个项目在 AWS 上启动后都可以正常工作，我收到下一个错误 502 Bad Gateway。

• 这类似于主要问题： ModuleNotFoundError: No module named 'ebddjango/wsgi'

wsg 文件：

import os from django.core.wsgi 
import get_wsgi_application 
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'ebddjango.settings') application = get_wsgi_application() 

配置：

option_settings: 
aws:elasticbeanstalk:container:python: 
WSGIPath: ebddjango/wsgi:application

Answer 1

在你的 .config 文件中尝试

option_settings:
  aws:elasticbeanstalk:application:environment:
    DJANGO_SETTINGS_MODULE: ebddjango.settings
  aws:elasticbeanstalk:container:python:
    WSGIPath: ebddjango.wsgi:application
  aws:elasticbeanstalk:environment:proxy:staticfiles:
    /static: static

Answer 2

似乎我遇到了完全相同的问题：我按照官方教程进行操作，但最终出现 502 错误。 我在Stackify上找到了我的解决方案，他们说：

亚马逊Linux 2平台上的Python 3.7+确实需要gunicorn。

所以我所做的只是在安装 django 之后运行以下命令（本教程的设置 Python 虚拟环境并安装 Django部分的第 3 点）

pip install gunicorn
