我的配置没问题，这曾经可以工作；我提取了一些新的应用程序代码，现在收到 502 bad gateway 错误（在我提取应用程序代码之前，站点运行良好）。我已经做了service gunicorn restart 和systemctl restart gunicorn 并且仍然收到 502 bad gateway 错误。有人可以帮忙吗？

这是一个 django 项目，物有所值。

Answer 1

运行 gunicorn --bind=unix:/home/mike/movingcollage/movingcollage.sock movingcollage.wsgi:application --preload --loglevel=debug 并在解决导入错误后让它继续运行
