Django应用程序已部署到Digitalocean 502 Bad Gateway

Question

我已经将django应用程序（在本地工作）复制到我安装django一键式应用程序的Digitalocean的Droplet中。 我收到502错误网关，无法理解原因。

我是Django的新用户，并且刚部署到服务器，因此无法理解该错误。 我一直在寻找答案，但是找不到适合我的情况的解决方案。 有没有办法得到更详细的错误？ 谢谢

Answer 1

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

确保已将Nginx设置为连接到Django应用程序在其上提供流量的套接字（ unix:/... ）或http端点。
