我是 Django 和部署到服务器的新手，我无法理解错误。我一直在寻找答案，但找不到适合我的解决方案。有没有办法获得更详细的错误？谢谢

【问题讨论】：

DigitalOcean 有很好的部署 Django 的教程。你看过他们吗？看起来 gunicorn 的服务不正确。

标签： python django nginx digital-ocean

【解决方案1】：

在您发布的日志中显示 upstream: "http://unix:/home/django/gunicorn.socket:/" - 看起来您的 Nginx 服务器配置错误，无法连接到 Django 应用程序。

确保将 Nginx 设置为连接到套接字 (unix:/...) 或 Django 应用提供流量的 http 端点。
