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.rpm yum install at rpm -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.deb dpkg -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）。
