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

Question

我已經將django應用程序（在本地工作）復制到我安裝django一鍵式應用程序的Digitalocean的Droplet中。 我收到502錯誤網關，無法理解原因。

我是Django的新用戶，並且剛部署到服務器，因此無法理解該錯誤。 我一直在尋找答案，但是找不到適合我的情況的解決方案。 有沒有辦法得到更詳細的錯誤？ 謝謝

Answer 1

在您發布的日志中，它說在upstream: "http://unix:/home/django/gunicorn.socket:/" -看起來您的Nginx服務器配置錯誤，它無法連接到Django應用。

確保已將Nginx設置為連接到Django應用程序在其上提供流量的套接字（ unix:/... ）或http端點。
