Django应用部署到Digitalocean 502 Bad Gateway

Question

我已经将我的django应用程序(在本地工作)复制到来自Digitalocean的一个水滴，在那里我安装了django 1-click应用程序。我得到了502 Bad Gateway，却无法理解其中的原因。

我对Django和部署到服务器都是新手，我不能理解这个错误。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信息？谢谢

Answer 1

在你发布的日志中写着upstream: "http://unix:/home/django/gunicorn.socket:/" --看起来你的Nginx服务器配置错误，它无法连接到Django应用程序。

确保Nginx设置为连接到套接字(unix:/...)或http端点，Django应用程序在该端点上为流量提供服务。
