Django部署Apache2上配置mod_wsgi后出现404错误

Question

在Apache2上为Django部署配置mod_wsgi后，我得到了404错误。

ENV：Ubuntu服务器14.04.2LTS/Apache的2.4/1.8的Django/Python的3.4

我的apache2.conf是如下（内容我在conf文件的末尾添加）：

AddHandler cgi-script .cgi .pl .py 

WSGIScriptAlias//var/www/html/youknowmanagementsystem/youknow/wsgi.py 
WSGIPythonPath /var/www/html/youknowmanagementsystem 

Alias /static/ /var/www/html/youknowmanagementsystem/statics/ 

<Directory /var/www/html/youknowmanagementsystem/statics> 
Require all granted 
</Directory> 

<Directory /var/www/html/youknowmanagementsystem/youknow> 
<Files wsgi.py> 
Require all granted 
</Files> 
</Directory> 

我检查了我的Apache2错误日志，它表明：

这个解决我的问题：https://askubuntu.com/questions/569550/assertionerror-using-apache2-and-libapache2-mod-wsgi-py3-on-ubuntu-14-04-python

的Ubuntu 14.04自带mod_wsgi的3.4。根据 https://code.djangoproject.com/ticket/22948#comment:2我们需要为Python 3.4使用 mod_wsgi版本4.2+。

将mod_wsgi安装到最新版本的最好方法是使用pip（可以在virtualenv中）获得 ，然后将其模块安装到系统范围内的Apache 。在我的情况下，我使用/ venv_path中的virtualenv设置。

1）取下有问题的包和安装依赖性

sudo apt-get remove libapache2-mod-wsgi-py3

sudo apt-get install apache2-dev

2）中的virtualenv与PIP

. /venv_path/bin/activate pip install mod_wsgi

3安装mod_wsgi的）安装到的Apache（系统全）

sudo /venv_path/bin/mod_wsgi-express install-module

sudo vi /etc/apache2/mods-available/wsgi_express.load /etc/apache2/mods-available/wsgi_express.conf

含量/etc/apache2/mods-available/wsgi_express.load

LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi-py34.cpython-34m.so

内容/等/ apache2的/ MODS的可用/ wsgi_express.conf

WSGIPythonHome /venv_path

4）启用模块并重启Apache。

sudo a2enmod wsgi_express

sudo service apache2 restart

5）检查是否有在/ var没有错误/日志/的Apache2 /错误。日志

所以我们需要像上面的链接一样安装mod_wsgi，它现在可以工作。
