用于生产的 Django 部署

Question

我的本地机器上有 Django 运行，但我正处于要将 Django 站点部署到生产服务器的位置。我的服务器是 Ubuntu 14.04 服务器，Apache 2.x、python 2.7 和 Django 1.8。我尝试使用 Django 的 Apache 基本配置和 mod_wsgi link，但我不断收到以下错误：

my site

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

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.,  
mod_wsgi (pid=14962): Exception occurred processing WSGI script '/var/www/tmws/tmws/wsgi.py'.,  
Traceback (most recent call last):,

  @six.python_2_unicode_compatible,  
AttributeError: 'module' object has no attribute 'python_2_unicode_compatible',

这是我的 apache2.conf 文件：

...

<Directory /var/www/tmws/tmws>
    <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>

如有任何帮助，我们将不胜感激。如果还有什么我可以post帮忙告诉我的。

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 6 升级到最新版本应该可以修复它：

pip install --upgrade six

也就是说，强烈建议从虚拟环境运行 Django 而不是在系统级别安装包 - 如果有系统包由于某种原因依赖于旧版本 six 那么你可能运行陷入其他问题。
