本文介绍了在Apache服务器上运行Python Web应用程序的三种方式：1) 使用CGI，通过修改配置文件和创建Python脚本来实现；2) 利用Mod_Python模块，配置Apache并设置PythonHandler来提高性能；3) 使用Mod_wsgi，一个高性能的Python Web服务器网关接口。每种方法都涉及到Apache配置和Python脚本的编写。

1, 传统CGI：

vim /var/www/cgi-bin/hello.py

#!/usr/bin/python
# -*- coding: utf-8 -*-

print "Content-type: text/html\n"
print "Hello World"

chmod a+x hello.py

vim /etc/httpd/conf/httpd.conf
ScriptAlias /cgi-bin/ /var/www/cgi-bin/

2, Mod_Python (http://www.modpython.org/)

wget http://archive.apache.org/dist/httpd/modpython/mod_python-3.3.1.tgz

./configure --with-apxs=/data/apache2221/bin/apxs --with-python=/usr/bin/python
make
make install

vim /etc/httpd/conf.d/python.conf
LoadModule python_module modules/mod_python.so

<Directory /var/www/mod-python>
    AddHandler mod_python .py
    # mod_python.publisher
    PythonHandler mod_python.publisher

PythonDebug On
</Directory>

vim /var/www/mod-python/mod_python_publisher.py

#!/usr/bin/python
# -*- coding: utf-8 -*-

from mod_python import apache

def index(req):
    req.log_error('handler')
    req.content_type = 'text/html'
    req.send_http_header()
    req.write('<html><head><title>Testing mod_python</title></head><body>')
    req.write('Hello World! - mod_python.publisher')
    req.write('</body></html>')

<Directory /var/www/mod-python>
    AddHandler mod_python .py
    # custom handler
    PythonHandler mod_python_handler

PythonDebug On
</Directory>

vim /var/www/mod-python/mod_python_handler.py

#!/usr/bin/python
# -*- coding: utf-8 -*-

from mod_python import apache

def handler(req):
    req.log_error('handler')
    req.content_type = 'text/html'
    req.send_http_header()
    req.write('<html><head><title>Testing mod_python</title></head><body>')
    req.write('Hello World! - custom handler')
    req.write('</body></html>')
    return apache.OK

3, Mod_wsgi (http://code.google.com/p/modwsgi/)
wget http://modwsgi.googlecode.com/files/mod_wsgi-3.3.tar.gz

./configure --with-apxs=/data/apache2221/bin/apxs --with-python=/usr/bin/python
make
make install

vim /data/apache2221/conf/httpd.conf
LoadModule wsgi_module modules/mod_wsgi.so

WSGIScriptAlias /wsgi/ /var/www/wsgi/
<Directory "/var/www/wsgi">
Order allow,deny
Allow from all
</Directory>

vim /var/www/wsgi/hello.py

#!/usr/bin/python
# -*- coding: utf-8 -*-

def application(environ, start_response):
    status = '200 OK'
    content_type = 'text/html'

    output = ['Hello World']

    response_headers = [('Content-type', content_type)]
    start_response(status, response_headers)
    return output
