关于apache：使用WSGI在Windows XAMPP中设置Python路径


Setting Python Path in Windows XAMPP using WSGI

我正在Webfaction上设置实时服务器的开发版本，在本地计算机XP上的虚拟Apache服务器环境中运行Django应用程序(无任何错误运行)，在Python 2.6上运行XAMPP Lite，可以从中提交更改通过Git。

XAMPP已启动并在Python上运行正常，并且服务器在加载WSGI模块后完美启动。问题是当我设置Python路径时，它们的一半设置为'nix格式(带有/)，而一半设置为Windows(带有反斜杠)。

这是本地计算机Apache错误，显示损坏的python路径：

import os, sys

sys.path.append('C:/SERVER/Python26/')
sys.path.append('C:/SERVER/Python26/Lib/site-packages/website-cms/webapps/django')
sys.path.append('C:/SERVER/Python26/Lib/site-packages/website-cms/webapps/django/lib/python2.5')

from django.core.handlers.wsgi import WSGIHandler

#Add the path to Django itself
os.environ['DJANGO_SETTINGS_MODULE'] = 'website.settings'
application = WSGIHandler()

Apache httpd.conf是XAMPP(而非虚拟实例)的默认设置，并添加了以下内容以加载wsgi模块

1
LoadModule wsgi_module modules/mod_wsgi-win32-ap22py26-3.3.so

＆指向wsgi文件：

1
WSGIScriptAlias / C:/SERVER/Python26/Lib/site-packages/website-cms/webapps/django/dev.wsgi

我知道XAMPP服务器使用的是Python2.6(我不得不使用TortoiseGIT)，生产版本为2.5(由Web主机托管)，但这似乎不是罪魁祸首-我仍然希望至少能够设置正确的路径！

欢迎获得有关使用Python玩球的所有建议！

我的电脑具有Python 2.6，因此我将以Python 2.6为目标版本的情况下使用所有配置。

  • 下载最新的xampp(http://www.apachefriends.org/en/xampp-windows.html)，截至2010年11月29日，版本1.7.3是最新的。
  • 为Windows安装xampp，我将其安装为c： xampp
  • 下载并安装Python 2.6(http://www.python.org/download/releases/2.6/)
  • 下载Windows版的wsgi-http://code.google.com/p/modwsgi/wiki/DownloadTheSoftware?tm=2
    如有必要，请参阅文档-http://code.google.com/p/modwsgi/wiki/InstallationOnWindows
  • 将so文件复制到模块目录C： xampp apache modules中，不要忘记将其重命名为mod_wsgi.so
  • 将以下行添加到C： xampp apache conf httpd.conf

    • LoadModule wsgi_module模块/mod_wsgi.so
  • 使用C： xampp xampp-control.exe重新启动Apache

    • 为了进行测试，我执行了以下步骤。

  • 进入C： xampp htdocs wsgi scripts目录，然后复制测试test.wsgi。

    • test.wsgi如下。

    """
    A simple WSGI test application.

    Its main purpose is to show that WSGI support works (meaning that the
    web server and the WSGI adaptor / support module are configured correctly).

    As a nice plus, it outputs some interesting system / WSGI values as a nice
    HTML table.

    The main use of this script will be using the WSGI"application" defined
    below within your production WSGI environment. You will use some code similar
    to what you see at the end of this script to use the application from that
    environment. For the special case of apache2/mod_wsgi, it shoud be possible
    to directly use this file.

    If you start this script from the commandline either with python2.5 or with
    and older python + wsgiref module installed, it will serve the content on
    http://localhost:8000/ - this is mainly for debugging THIS script.

  • 将此行添加到httpd.conf中，包括" conf / other / wsgi.conf"
  • 重新启动Apache。
  • 在网络浏览器中输入" localhost / test"或" localost / wsgi / test.wsgi"时，您将看到wsgi信息。

    我也遇到了"服务器错误"，并在Apache error.log文件中查看：这是由于注释行"它的主要目的是……"引起的空格或换行符
