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>
