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

【问题标题】：Deploying a Django application to Elastic Beanstalk AWS 502 Bad Gateway将 Django 应用程序部署到 Elastic Beanstalk AWS 502 错误网关
【发布时间】：2022-01-29 16:33:38
【问题描述】：

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。

这似乎是主要问题：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

状态：

【问题讨论】：

您好，您在使用 .ebextensions 文件夹和 .config 文件吗？
请编辑你的答案并给我看你的配置文件，如果可能的话，你的 ebddjango/wsgi.py 文件
import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'ebddjango.settings') application = get_wsgi_application() config: option_settings: aws:elasticbeanstalk:container:python : WSGIPath: ebddjango/wsgi:application

标签： python django amazon-web-services amazon-elastic-beanstalk

【解决方案1】：

似乎我遇到了完全相同的问题：我关注了official tutorial，但最终出现了 502 错误。我在Stackify 上找到了我的解决方案，他们说：

Amazon 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 Set up a Python virtual environment and install Django 部分的第 3 点）

pip install gunicorn

【解决方案2】：

在您的 .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

【讨论】：

现在：ModuleNotFoundError：没有名为“应用程序”的模块
很多事情都可能引发这个错误，但它可能是您的设置文件没有像这里stackoverflow.com/questions/70332515/… 那样设置为生产，或者您可能压缩文件错误，您应该压缩文件而不是您的此处所说的文件夹docs.aws.amazon.com/elasticbeanstalk/latest/dg/… 或者它可能是python版本之间的差异stackoverflow.com/questions/62479386/…
我用一个完全空的 django 项目进行了测试。 2 次我通过命令提示，启动所有项目并推动 AWS 502。之后我通过 aws 控制台进行压缩和上传，每次结果都是相同的 502。感谢您的良好输入，我会脸颊设置。 py 文件以查看其中发生的情况，这可能是不是部署设置的问题。
