Apache / mod_wsgi ModuleNotFoundError

Question

我正在尝试将Ubuntu VPS托管在Apache/mod_wsgi上的Django网站。如果我以嵌入式模式运行，则将加载网站。

WSGIScriptAlias / /home/admin/web/mywebsite/myproject/wsgi.py
WSGIPythonHome /home/admin/web/mywebsite/venv
WSGIPythonPath /home/admin/web/mywebsite

<Directory /home/admin/web/mywebsite/myproject>
    <Files wsgi.py>
        Order deny,allow
        Allow from all
    </Files>
</Directory>

但是，如果尝试在daemon mode中运行它，则会出现错误：ModuleNotFoundError: No module named 'myproject'。

WSGIDaemonProcess myproject python-home=/home/admin/web/mywebsite/venv python-path=/home/admin/web/mywebsite socket-user=#1001
WSGIProcessGroup myproject
WSGIScriptAlias / /home/admin/web/mywebsite/myproject/wsgi.py

我的WSGI文件：

import os

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'

application = get_wsgi_application()

如果我运行manage.py命令，它将在嵌入式和守护程序模式下显示相同的ModuleNotFoundError错误。可能有什么问题吗？

尝试使用此方法进行部署。在nginx释放nginx单元之后，您最忘记了gunicorn，AWS弹性beantalk（EB）和在nginx上部署django的旧方法。

仅使用nginx单元来部署django应用程序，问题就已经解决了。

本教程可帮助您快速，安全地部署django，并且性能比gunicorn和uwsgi高得多
