在Mac OS上使用mod_wsgi连接Python与Apache服务器

一、安装mod_wsgi 3.4：

./configure --with-apxs=/Users/levin/dev/apache2.2.27/bin/apxs --with-python=/usr/bin/python
make
make install

编辑httpd.conf使Apache导入模块mod_wsgi.so以及引入vhost配置文件：

LoadModule wsgi_module modules/mod_wsgi.so
Include conf/extra/httpd-vhosts.conf

编辑extra/httpd-vhosts.conf新建项目并增加gzip压缩python输出的文本：

Listen 8001

<VirtualHost *:8001>
 WSGIScriptAlias / /Users/levin/dev/py/webapp/app.py/
 Alias /assets /Users/levin/dev/py/webapp/static/
 AddType text/html .py
 <Directory /Users/levin/dev/py/webapp/>
   Order deny,allow
   Allow from all
   SetOutputFilter DEFLATE       #开启gzip
   SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary      #图片不开启gzip
   SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|rar)$ no-gzip dont-vary   #压缩包不开启gzip
   SetEnvIfNoCase Request_URI .(?:pdf|doc)$ no-gzip dont-vary
   AddOutputFilterByType DEFLATE text/*
   AddOutputFilterByType DEFLATE application/javascript application/x-javascript application/xml
   AddOutputFilterByType DEFLATE application/x-httpd-php
 </Directory>
</VirtualHost>

先写个测试脚本app.py

def application(environ, start_response):
 start_response('200 OK', [('Content-Type', 'text/html')])
 return ['Hello, world.']

或者使用web.py框架：

import web

urls = (
 '/.*', 'hello',
)

class hello:
 def GET(self):
   return "Hello, world."

application = web.application(urls, globals()).wsgifunc()

在浏览器中访问： http://localhost:8001/，看到Hello, world.就算安装成功了。

二、Django使用中可能遇到的麻烦解决：
1.修改setting.py文件：

DEBUG = True
TEMPLATE_DEBUG = False
ALLOWED_HOSTS = ['localhost']

2.修改项目中的wsgi.py，这个是建项目的时候就自带创建的，跟setting.py在同一目录，我傻傻的自己创建好多次，后来才发现文件位置不对，悲剧了。

＃/Library/WebServer/Documents是apache中DocumentRoot位置
＃votebing是我建的项目
import sys
sys.path.append('/Library/WebServer/Documents/votebing')

3.修改apache安装目录中的httpd.conf，我的是在/etc/apache2/httpd.conf

#载入mod_wsgi
LoadModule wsgi_module /usr/libexec/apache2/mod_wsgi.so

WSGIScriptAlias /votebing /Library/WebServer/Documents/votebing/votebing/wsgi.py
WSGIPythonPath /Library/WebServer/Documents

<Directory /Library/WebServer/Documents/votebing/>
<Files wsgi.py>
Order deny,allow
Allow from all
</Files>
</Directory>
Alias /media/ /Library/WebServer/Documents/votebing/media/
Alias /static/ /Library/WebServer/Documents/votebing/static/

<Directory /Library/WebServer/Documents/votebing/static>
Allow from all
</Directory>

<Directory /Library/WebServer/Documents/votebing/media>
Allow from all
</Directory>
