用WSGI和Apache安装综合报告

Question

我是Debian挤压官方回购公司安装的Roundup1.4，希望使用mod_wsgi在我的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>

我在/var/roundup/support中使用roundup-admin install安装跟踪器，配置它，然后使用roundup-admin initialise进行初始化。然后我被创建为apache/roundup.wsgi

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

当在http://support.domain.com打开我的站点时(当然这个url有点不同)，我有HTTP 500 Internal Server Error，并使用：

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

到底怎么回事？如何正确地使用wsgi (而不是cgi)运行综合报告？或者去哪里看看为什么没有启动响应呢？

编辑

综合报告的安装手册显示，wsgi处理程序看起来如下所示：

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()

但这没有反应。浏览器永远加载它，没有消息或服务器日志。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。因此，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，例如：

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!

一定有办法从RequestDispatcher运行我的应用程序..。

Answer 1

根据本期的说法，这是一个许可问题。用下列方法解决：

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

其中，/var/roundup/support/中的文件具有适当的访问权限，其中roundup作为所有者和组。

Answer 2

尝试：

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

mod_wsgi所需要的是一个“应用程序”对象，它是一个有效的WSGI应用程序入口点。

您不需要自己启动WSGI服务器或FASTCGI适配器，就像您一直试图做的那样。
