Question

我正在部署django项目并获得500错误（请参阅服务器日志错误）。

我在哪里做错了？

一些注意事项：

CENTOS
mod_wsgi已安装
相同的python（2.7）和django（1.9.6）版本开发和部署environement
在deploy environement中使用virtualenv

服务器日志错误

Answer 1

正如Daniel指出的那样，错误表明你的mod_wsgi是为Python 2.6编译的。为了使用Python 2.7，您需要安装mod_wsgi，并根据Python 2.7编译它。你不能试图通过简单地引用你的Python 2.7虚拟环境来强迫它使用Python 2.7，这不是它的工作原理。

您可以使用以下所述的测试应用程序验证Python版本mod_wsgi的编译内容：

http://modwsgi.readthedocs.io/en/develop/user-guides/checking-your-installation.html#python-installation-in-use

您需要卸载mod_wsgi模块并安装为Python 2.7构建的版本，可以从系统软件包（如果可用）安装，也可以从源代码构建，如果没有可用于Python 2.7的mod_wsgi的系统软件包。

我还建议你检查关于使用mod_wsgi的Django文档，并确保你使用守护进程模式。

https://docs.djangoproject.com/en/1.10/howto/deployment/wsgi/modwsgi/#using-mod-wsgi-daemon-mode

请注意，Django文档仍然没有遵循所有最佳实践。您应该使用site-packages来引用虚拟环境，而不是在python-path中明确添加python-home。参见：

http://blog.dscpl.com.au/2014/09/using-python-virtual-environments-with.html

Answer 2

您没有使用正确的python版本，但您可以使用WSGIPythonHome指令指定在apache conf中使用哪个版本。

添加

WSGIPythonHome /path/to/your/virtualenv

到你的Apache配置，

通过这种方式，您可以使用virtualenv中的解释器。

编辑：

由于您可能希望专门为您的VirtualHost定义python home（WSGIPythonHome范围内不能使用VirtualHost），您可以使用WSGIDaemonProcess指令：

<VirtualHost *:80>
  ServerName example.com
  [...]

  WSGIDaemonProcess example.com python-home=/path/to/venv python-path=<python-path>
  WSGIProcessGroup example.com

</VirtualHost>

目标WSGI脚本'../wsgi.py'无法作为Python模块
