用于测试 FastCGI 的 WSGI Python 适配器：启动 WSGI 服务器时出错答案

【问题标题】：WSGI Python adapter to test FastCGI: Error starting WSGI server用于测试 FastCGI 的 WSGI Python 适配器：启动 WSGI 服务器时出错

【问题描述】：

当我尝试运行 WSGI Python 脚本以从 tutorial 测试 FastCGI 时：

#!/usr/bin/env python
# -*- coding: UTF-8 -*-

from cgi import escape
import sys, os
from flup.server.fcgi import WSGIServer

def app(environ, start_response):
    start_response('200 OK', [('Content-Type', 'text/html')])

    yield '<h1>FastCGI Environment</h1>'
    yield '<table>'
    for k, v in sorted(environ.items()):
         yield '<tr><th>%s</th><td>%s</td></tr>' % (escape(k), escape(v))
    yield '</table>'

WSGIServer(app).run()

它会导致以下结果，从错误日志中，根据返回的应用状态 0 并不清楚出了什么问题。可能是我遗漏了一些东西。

Mod_python error: "PythonHandler mod_python.publisher"

Traceback (most recent call last):

  File "/usr/local/lib/python2.7/site-packages/flup/server/fcgi_base.py", line 601, in _end
    sys.exit(appStatus)

SystemExit: 0

一个提示可能是它仅在我通过 Apache 运行它时发生。在命令行中它工作正常。

【解决方案1】：

看起来您正在尝试通过 FCGI 运行 WSGI 应用程序，但使用的是 mod_python。如果必须使用 FCGI，则需要使用 mod_fastcgi。但是，实际上您应该单独使用 mod_wsgi ，而不要使用它或 Flup。
