使用 AWS Elastic Beanstalk 部署 Django 应用程序时出现 502 Bad Gateway nginx/1.20.0 错误

时间：2021-07-26 21:54:52

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

我一直密切关注 how to deploy Django apps using Elastic Beanstalk 上的 AWS 文档，直到我在打开应用程序时收到 502 Bad Gateway nginx/1.20.0 错误。从那里，我遵循了遇到类似问题的用户提供的几个解决方案。具体来说，我 added a Procfile 并开始编辑我的 django.config 文件的设置方式。但是，错误仍然存​​在，我需要一些有关如何解决此问题的指导。以下是相关的日志和文件：

从表面上看，部署似乎是成功的。然而，基于一些其他类似的帖子，nginx 日志似乎表明让 gunicorn 作为 Web 服务器网关接口工作可能存在问题。关于如何解决这个问题有什么建议吗？
