Django生产部署

Question

我在本地计算机上运行了Django，但是现在我想将Django站点部署到生产服务器上。 我的服务器是Ubuntu 14.04服务器，具有Apache 2.x，python 2.7和Django 1.8。 我已经尝试将Django的基本配置用于Apache和mod_wsgi 链接 ，但我一直收到以下错误：

我的网站

内部服务器错误

服务器遇到内部错误或配置错误，无法完成您的请求。

这是我收到的Apache错误日志中的错误：

mod_wsgi (pid=14962): Target WSGI script '/var/www/tmws/tmws/wsgi.py' cannot be loaded as Python module.,

这是我的apache2.conf文件：

    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>

...

WSGIScriptAlias / /var/www/tmws/tmws/wsgi.py
WSGIPythonPath /var/www/tmws

这是我的wsgi.py文件：

import os, sys

from django.core.wsgi import get_wsgi_application

sys.path.append('/home/ubuntu/gather/src')
sys.path.append('/usr/local/lib/python2.7/dist-packages')
sys.path.append('/var/www/tmws')
sys.path.append('/var/www/tmws/tmws')

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "tmws.settings")

application = get_wsgi_application()

这是我的网站.conf文件：

<VirtualHost *:80>
    ServerAdmin xxxxxxxx
    ServerName xxxxxxxxxxx
    DocumentRoot /var/www/tmws
    WSGIScriptAlias / /var/www/tmws/tmws/wsgi.py

    ErrorLog ${APACHE_LOG_DIR}/TMWSerror.log
    CustomLog ${APACHE_LOG_DIR}/TMWSaccess.log combined

</VirtualHost>

任何帮助将不胜感激。 如果还有其他可以帮忙的地方，请告诉我。

您的系统可能正在使用不包含python_2_unicode_compatible方法的six python软件包的旧版本。 将六个升级到最新版本应该可以解决此问题：

pip install --upgrade six

就是说，强烈建议从虚拟环境中运行Django，而不是在系统级别安装软件包-如果某些系统软件包由于某种原因依赖于six旧版本，那么您可能会遇到其他问题。
