django - 未找到（通过 digitalocean、nginx、ubuntu、Gunicorn 部署）
问题描述
我尝试通过 digitalocean、nginx、ubuntu 和 Gunicorn 部署 Django。
我遵循了digitaloccean 提供的教程。在与 Gunicorn 绑定之前，一切都很好。
我能够使用运行“ manage.py runserver 0.0.0.0:8000”并且能够在IP地址的8000端口上看到该网站；
但是，当我尝试跑步时gunicorn --bind 0.0.0.0:8000 biostar.wsgi
(virtualcrew) corey@crew:~/digitalocceancrew/digitalcrew$ gunicorn --bind 0.0.0.0:8000 biostar.wsgi

,并再次尝试连接IP地址，出现404 not found错误。输出
但是当我试图跑sudo gunicorn --bind 0.0.0.0:8000 biostar.wsgi

我有以下问题：
- 什么可能导致此错误？
- 能在本地服务器上运行是否意味着错误不是源代码引起的？
- 我可以尝试什么来解决这个问题？
谢谢 ！！！
