Apache wgsi和Django没有名为django ImportError的模块

标签： django python-3.x apache virtualenv mod-wsgi


在阅读the django docs about apache and wsgi和Graham Dumpleton's posts后，我尝试安装django生产站点
我还花了几个小时在stackoverflow和其他论坛上解决了一个似乎很常见的错误（例如：this question seems similar），但是我所研究的解决方案都没有奏效。
我的apache服务器引发错误500，并且apache日志显示wsgi有一个ImportError

我已经用virtualenv安装了Django

Ubuntu 16.04.3
Python 3.6.3
virtualenv 16.0.0
Django 2.0.7
Apache2.4.18
mod_wsgi 3.5.1+

以下是apache日志的摘录：

这是我的wsgi.py文件：

import os
import time 
import traceback 
import signal 
import sys 

path='/home/david/DjangoProjects/unflat'
if path not in sys.path:
    sys.path.append(path) 

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "unflat.settings")
from django.core.wsgi import get_wsgi_application 
application = get_wsgi_application()

和httpd.conf文件：

Alias /static/ /home/david/DjangoProjects/static/
<Directory /home/david/DjangoProjects/static>
    Require all granted
</Directory>

WGIScriptAlias / /home/david/DjangoProjects/unflat/unflat/wsgi.py
WSGIPythonPath /home/david/DjangoProjects/unflat/
<Directory /home/david/DjangoProjects/unflat/unflat>
    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>

至少这里是000-default.com：

<VirtualHost *:80>

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    Alias /static /home/david/DjangoProjects/unflat/static
    <Directory /home/david/DjangoProjects/unflat/static>
        Require all granted
    </Directory>

    <Directory /home/david/DjangoProjects/unflat/unflat>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>

    WSGIDaemonProcess unflat python-home=/home/david/PythonEnv/djangounflatenv python-path=/home/david/DjangoProjects/unflat
    WSGIProcessGroup unflat
    WSGIScriptAlias / /home/david/DjangoProjects/unflat/unflat/wsgi.py process-group=unflat application-group=%{GLOBAL}

</VirtualHost>

如果有人可以帮助我发现所有这些东西出了问题，那将是巨大的，并且非常感谢。
谢谢。

由于此类问题可能有多个因素，并且取决于一组配置，因此我将展示现在可以解决的问题。我还添加了金枪鱼

ProxyPass /static !

/etc/apache2/mods-available/wsgi.load 

LoadModule wsgi_module /home/djangouser/DjangoProjects/unflatenv/lib/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpyt$

...至少启动python virtualenv，gunicorn和apache以启动服务器：

source /home/djangouser/DjangoProjects/unflatenv/bin/activate
gunicorn unflat.wsgi --daemon
sudo systemctl start apache2  
#sudo apachectl restart
