我正在按照說明指南進行操作，但左右都遇到了錯誤，我只想將我的 mysql 和 django 鏈接到我的頁面上。

Answer 1

根據您的文件，您的項目名稱是“tutorial”，錯誤是由

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tutorial.settings')

在 wsgi.py 中（但這是正確的 - 根本原因在於您的非標准文件夾結構）。 您的文件夾結構如何？

應該按照django標准：

src/
   tutorial/
      tutorial/
         settings.py
         urls.py
         wsgi.py

從您的 Apache 配置中，我可以看到 wsgi.py 不在正確的文件夾中。

應該：

WSGIScriptAlias / /home/ubuntu/django-project/src/tutorial/tutorial/wsgi.py
