Question

我的一个AWS Linux Server中有一个Python Django站点。首先，让我告诉你我在服务器上托管我的Django应用程序所做的工作。默认情况下，服务器已安装Python 2.6.9。对于我的应用程序，我已经在不同的位置（/opt/python2.7.6）编译和安装了Python 2.7.6。不过，默认的python是2.6.9。我的应用程序位于一个虚拟环境下，该环境是针对这个新安装的Python（2.7.6）创建的。我的Web服务器是Apache2（版本2.4），并使用以下命令通过编译Python 2.7.6来安装WSGI模块。

./ configure --with-python = / opt / python2.7.6 / bin / python

我已经相应地配置了apache，我收到以下错误。请告诉我如何解决这个问题。

我已经尝试了许多方法来解决谷歌建议中的这个问题，但还没有工作。

以下是我的apache conf文件。

<VirtualHost  *:80>
ServerName www.example.com

DocumentRoot /home/testuser/example.com
LogLevel info
ErrorLog /home/testuser/http_error.log
CustomLog /home/testuser/http_access.log combined

WSGIDaemonProcess www.example.com processes=2 threads=15 display-name=%{GROUP} python-path=/home/testuser/example.com:/home/testuser/venv/lib/python2.7/site-packages
WSGIProcessGroup www.example.com

WSGIScriptAlias / /home/testuser/example.com/example/wsgi.py
Alias /media /home/testuser/site_assets/media
Alias /static /home/testuser/example.com/.static_built
<Directory /home/testuser/example.com/example>
    <Files wsgi.py>
        Order allow,deny
        Allow from all
    </Files>
</Directory>
</VirtualHost>

请注意，该网站与独立的python runserver命令配合良好。

谢谢，

我解决了。我在我的服务器上运行了三个Python版本（2.7.6,2.6.9和2.7.10），但默认情况下它是2.6.9。即使我的python虚拟环境是针对2.7.6，Apache也没有为我的应用程序选择那个python。我不知道为什么会这样。当我添加** WSGIPythonHome *作为指向我的虚拟环境python时，在我的apache配置文件的顶部它完美地工作。请参阅下面更新的apache配置文件。

WSGIPythonHome /home/testuser/venv
<VirtualHost  *:80>
ServerName www.example.com

DocumentRoot /home/testuser/example.com
LogLevel info
ErrorLog /home/testuser/http_error.log
CustomLog /home/testuser/http_access.log combined

WSGIDaemonProcess www.example.com processes=2 threads=15 display-name=%{GROUP} python-path=/home/testuser/example.com:/home/testuser/venv/lib/python2.7/site-packages
WSGIProcessGroup www.example.com

WSGIScriptAlias / /home/testuser/example.com/example/wsgi.py
Alias /media /home/testuser/site_assets/media
Alias /static /home/testuser/example.com/.static_built
<Directory /home/testuser/example.com/example>
    <Files wsgi.py>
        Order allow,deny
        Allow from all
    </Files>
</Directory> 
</VirtualHost>
