mod_pagespeed是谷歌发布的加速httpd的优化模块，通过自动优化代码、压缩传输内容、自动缓存加速http，支持Centos/Debian系统

mod_pagespeed目前支持Apache和Nginx。Apache中简单的安装方法如下。安装完成之后，它会在yum里新建一个安装源，之后通过yum update更新就可以了

Centos/Fedora下安装：

#32位wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-stable_current_i386.rpm#64位wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-stable_current_x86_64.rpmyum install atrpm -U mod-pagespeed-*.rpm

Debina/Ubuntu下安装：

#32位wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-stable_current_i386.deb#64位wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-stable_current_x86_64.debdpkg -i mod-pagespeed-*.deb

重启httpd：

service httpd restart

查看pagespeed是否加载：

httpd -M|grep pagespeed

配置mod_pagespeed

Tips：mod_pagespeed 需要 Apache 加载 mod_deflate（一个将 web内容gzip压缩后传输的模块）。
