关键词：mod\_gzip http compress apache

内容摘要：  
HTTP压缩对于纯文本内容可压缩至原大小的40％一下，从而提供60％以上的数据传输节约，虽然WEB服务器会因为压缩导致CPU占用的略微上升，但是可以节约大量用于传输的网络IO。对于数据压缩带来的用户浏览速度提升（让页面符合8秒定律），这点总体负载5%-10%上升是非常值得的。毕竟通过数据压缩会比通过不规范的HTML代码优化要方便得多。

mod\_gzip的安装：

修改Makefile中的 apxs路径：然后make make install

配置：mod\_gzip+mod\_php  
LoadModule gzip\_module modules/mod\_gzip.so

...  
AddModule mod\_gzip.c

...  
*<IfModule mod\_gzip.c>  
mod\_gzip\_on Yes  
mod\_gzip\_minimum\_file\_size 1000  
mod\_gzip\_maximum\_file\_size 300000  
mod\_gzip\_item\_include file /.htm$  
mod\_gzip\_item\_include file /.html$  
mod\_gzip\_item\_include file /.php$  
mod\_gzip\_item\_include file /.php3$  
mod\_gzip\_item\_include mime text/.\*  
mod\_gzip\_item\_include mime httpd/unix-directory  
\# mod\_gzip的临时工作目录: mkdir /tmp/mod\_gzip; chmod -R 777 mod\_gzip  
mod\_gzip\_temp\_dir /tmp/mod\_gzip  
mod\_gzip\_dechunk Yes  
mod\_gzip\_keep\_workfiles No  
</IfModule>*

mod\_gzip和mod\_php的配合：不要让mod\_gzip和mod\_php使用同一个临时目录，php\_session存放目录可以通过 php.ini设置到session.save\_path = /tmp/php\_sess  
  
mod\_gzip和Resin配合：  
从resin的邮件列表上查到的：要让mod\_gzip在mod\_caucho后加载，否则mod\_gzip不起作用  
...othr modules  
AddModule mod\_so.c  
AddModule mod\_caucho.c  
\#notice: mod\_gzip must load after mod\_caucho  
AddModule mod\_gzip.c  
AddModule mod\_expires.c  
...

配置：mod\_gzip + resin  
*<IFModule mod\_gzip.c>  
mod\_gzip\_on Yes  
mod\_gzip\_dechunk yes  
mod\_gzip\_keep\_workfiles No  
mod\_gzip\_minimum\_file\_size 3000  
mod\_gzip\_maximum\_file\_size 300000  
mod\_gzip\_item\_include file /.html$  
mod\_gzip\_item\_include mime text/.\*  
mod\_gzip\_item\_include mime httpd/unix-directory  
mod\_gzip\_item\_include handler caucho-request  
</IFModule>*

配置：mod\_gzip + mod\_proxy 反相代理加速并压缩 IIS  
注意要增加缺省的文件编码属性映射。  
AddType text/html .asp  
AddType text/html .aspx

*<IFModule mod\_gzip.c>*

*AddType text/html .asp  
AddType text/html .aspx  
mod\_gzip\_on Yes  
mod\_gzip\_dechunk yes  
mod\_gzip\_keep\_workfiles No  
mod\_gzip\_minimum\_file\_size 3000  
mod\_gzip\_maximum\_file\_size 300000  
mod\_gzip\_item\_include file /.html$  
mod\_gzip\_item\_include file /.asp$  
mod\_gzip\_item\_include file /.aspx$  
mod\_gzip\_item\_include mime text/.\*  
mod\_gzip\_item\_include mime httpd/unix-directory  
mod\_gzip\_item\_include handler proxy-server  
</IFModule>*
