Nginx下安装配置PageSpeed模块，轻松完成网站提速

做为Nginx组件，ngx_pagespeed将重写你的网页，让用户以更快的速度进行访问。重写的工做包括压缩图片、缩减CSS和JavaScript、扩展缓存时间，一样还包括其它一些最佳实践：

• 优化缓存——整合应用程序的数据和逻辑
• 最小化round-trip次数——削减连续的请求/响应周期数
• 最小化请求开销——削减上传大小
• 最小化负载大小——削减响应、下载及缓存页面大小
• 优化浏览器渲染——改善浏览器页面布局
• 移动方面的优化——优化站点移动网络和设备方面的相关特性

下载解压PageSpeed模块

cd /root/lnmp/source wget https://github.com/pagespeed/ngx_pagespeed/archive/release-1.5.27.3-beta.zip unzip -q release-1.5.27.3-beta wget https://dl.google.com/dl/page-speed/psol/1.5.27.3.tar.gz tar xzf 1.5.27.3.tar.gz -C ngx_pagespeed-release-1.5.27.3-beta/

查看线上版本编译参数

# /usr/local/nginx/sbin/nginx -V nginx version: nginx/1.4.0 built by gcc 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) TLS SNI support enabled configure arguments: --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module

增长ngx_pagespeed模块从新编译

# wget http://nginx.org/download/nginx-1.4.1.tar.gz # tar -xvzf nginx-1.4.1.tar.gz # cd nginx-1.4.1/ # ./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --add-module=../ngx_pagespeed-release-1.5.27.3-beta/ # make //注意只make 不要make install # mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx$(date +%m%d) #备份nginx原文件 # cp objs/nginx /usr/local/nginx/sbin/nginx #复制编译make后的文件覆盖nginx原文件 # /usr/local/nginx/sbin/nginx -t #检测nginx配置文件语法是否正确 nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok [0428/104829:INFO:google_message_handler.cc(33)] Shutting down ngx_pagespeed root nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful # kill -USR2 `cat /usr/local/nginx/logs/nginx.pid` #把nginx.pid改为nginx.pid.oldbin跟着启动新的nginx # kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin` #退出旧的nignx

使用ngx_pagespeed

# mkdir /var/ngx_pagespeed_cache
# chown www.www /var/ngx_pagespeed_cache
# cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf$(date +%m%d) #备份nginx配置文件
# vi /usr/local/nginx/conf/nginx.conf
server {
pagespeed on; #这2行建议放在给个server内，若是放在全局,测试discuz不能用？
pagespeed FileCachePath /var/ngx_pagespeed_cache;
location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" { add_header "" ""; }
location ~ "^/ngx_pagespeed_static/" { }
location ~ "^/ngx_pagespeed_beacon$" { }
location /ngx_pagespeed_statistics { allow 127.0.0.1; deny all; }
location /ngx_pagespeed_message { allow 127.0.0.1; deny all; }
}
# /usr/local/nginx/sbin/nginx -t
