Apache2 mod_wsgi、_sql 导入错误的 Django 问题

Question

我正在努力运行用于 django 的 apache2 服务器。我想尝试 gunicorn，但由于我希望在工作场所更频繁地安装 apache，所以我会坚持使用它。目前的问题在于（我认为）在 apache error.log 的摘录中可见的导入错误。我已经尝试了很多可能的配置，并且在它甚至没有导入 django 之前。我正在使用虚拟环境。来自 django 的开发者服务器对于应用程序和数据库都工作得很好。

现在来自 sites-available 文件夹的配置：

<Directory /home/pi/djangoProjects/pidjay/pidjay>
    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>

WSGIDaemonProcess pidjay python-path=/home/pi/djangoProjects/pidjay:/home/pi/djangoProjects/pidjay/venv/lib/python3.5/site-packages
WSGIProcessGroup pidjay
WSGIScriptAlias / /home/pi/djangoProjects/pidjay/pidjay/wsgi.py

如您所见，我用冒号指定了虚拟环境文件夹，其他方式导致无法导入django。环境中的python是ver 3.5（检查了两次），安装了sqlclient和django。当我尝试在 venv（已激活）内的 python 解释器中导入“_mysql”时，它工作得很好。

这是项目 settings.py:

的数据库设置

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': "pidjay",
    "USER": "user",
    "PASSWORD": "password"
}}

正如我所说，它适用于开发服务器。请帮我解决这个问题，非常感谢您！我很乐意提供任何其他信息！

Answer 1

正如格雷厄姆亲切指出的那样，问题在于版本不匹配。在官方文档的帮助下为 python 3.5 编译 mod_wsgi 并将其加载到 apache 后，它按预期工作。

Answer 2

如上所述，这是一种方法。

wget https://github.com/GrahamDumpleton/mod_wsgi/archive/4.5.14.tar.gz
tar -zxvf 4.5.14.tar.gz
cd mod_wsgi-4.5.14
./configure --with-python=/usr/bin/python3.5
make
make install
chmod 755 /usr/lib64/httpd/modules/mod_wsgi.so
