Apache2 使用WSGI和Apache设置综述

我是由Debian官方repo安装Roundup 1.4的，希望使用

mod_wsgi

在Apache服务器上运行它。主机配置：

<VirtualHost *:80>
    ServerName support.domain.com

    WSGIScriptAlias / /var/roundup/support/apache/roundup.wsgi
    WSGIDaemonProcess support.roundup user=roundup group=roundup threads=25
    WSGIProcessGroup support.roundup

    <Directory /var/roundup/support>
        <Files roundup.wsgi>
            Order allow,deny
            Allow from all
        </Files>
    </Directory>

    # ... some logging configuration
</VirtualHost>

在

http://support.domain.com

（当然这个url有点不同）我有HTTP响应

500内部服务器错误

，并使用以下内容登录：

mod_wsgi (pid=17433): Exception occured processing WSGI script '/var/roundup/support/apache/roundup.wsgi'.
RuntimeError: response has not been started

发生什么事了？如何正确使用wsgi（而不是cgi）运行综述？或者从何处寻找尚未启动响应的原因

Roundup的安装手册说wsgi处理程序如下所示：

from wsgiref.simple_server import make_server

# obtain the WSGI request dispatcher
from roundup.cgi.wsgi_handler import RequestDispatcher
tracker_home = 'demo'
app = RequestDispatcher(tracker_home)

httpd = make_server('', 8917, app)
httpd.serve_forever()

但这没有任何回应。浏览器将永远加载它，而无需消息或服务器日志。我认为从apache模块运行的脚本启动另一台服务器不是个好主意。所以我尝试了另一个代码示例：

from roundup.cgi.wsgi_handler import RequestDispatcher
tracker_home = '/var/roundup/support'
application = RequestDispatcher(tracker_home)

from flup.server.fcgi import WSGIServer
WSGIServer(application).run()

但这会引发一些错误，如：

WSGIServer: missing FastCGI param REQUEST_METHOD required by WSGI!
WSGIServer: missing FastCGI param SERVER_NAME required by WSGI!
WSGIServer: missing FastCGI param SERVER_PORT required by WSGI!
WSGIServer: missing FastCGI param SERVER_PROTOCOL required by WSGI!

必须有办法从RequestDispatcher运行我的应用程序…

试试：

from roundup.cgi.wsgi_handler import RequestDispatcher
tracker_home = '/var/roundup/support'
application = RequestDispatcher(tracker_home)

mod_wsgi需要的全部是一个“应用程序”对象，它是一个有效的wsgi应用程序入口点

您不需要像一直尝试的那样自己启动WSGI服务器或FASTCGI适配器。

根据这一点，这是一个权限问题。使用以下方法解决：

WSGIDaemonProcess support.roundup user=roundup group=roundup threads=25
WSGIProcessGroup support.roundup

其中

/var/roundup/support/

中的文件拥有

roundup

所有者和具有适当访问权限的组。

在我编写的上一次编辑上面，该编辑抛出运行时错误消息：

响应尚未启动

，但不知道原因。

WSGIDaemonProcess support.roundup user=roundup group=roundup threads=25
WSGIProcessGroup support.roundup
