Nginx安装配置PageSpeed模块实现网站加速

 　　作为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。重写的工作包括压缩图片、缩减CSS和JavaScript、扩展缓存时间，同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/src,　　wget https://github.com/pagespeed/ngx_pagespeed/archive/release-1.6.29.5-beta.zip,　　unzip -q release-1.6.29.5-beta,　　wget https://dl.google.com/dl/page-speed/psol/1.6.29.5.tar.gz,　　tar xzf 1.6.29.5.tar.gz -C ngx_pagespeed-release-1.6.29.5-beta,　　查看线上版本编译参数,　　# /usr/local/nginx/sbin/nginx -V,　　nginx version: nginx/1.4.1,　　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,　　增加ngx_pagespeed模块重新编译,　　# wget http://nginx.org/download/nginx-1.4.2.tar.gz,　　# tar -xvzf nginx-1.4.2.tar.gz,　　# cd nginx-1.4.2/,　　# ./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --add-module=../ngx_pagespeed-release-1.6.29.5-beta/,　　# make //注意只make 不要make install (如果报错请看下面),　　安装ngx_pagespeed (make) 32位操作系统可能会报如下错误,　　../ngx_pagespeed-release-1.6.29.5-beta/psol/lib/Release/linux/ia32/pagespeed_automatic.a(104.system.o.o): In function `cv::tempfile(char const*):,　　system.cpp:(.text._ZN2cv8tempfileEPKc+0x1e): warning: the use of `tmpnam is dangerous, better use `mkstemp,　　objs/addon/src/ngx_base_fetch.o: In function `net_instaweb::NgxBaseFetch::DecrefAndDeleteIfUnreferenced():,　　/root/lnmp/src/nginx-1.4.2/../ngx_pagespeed-release-1.6.29.5-beta/src/ngx_base_fetch.cc:185: undefined reference to `__sync_add_and_fetch_4,　　collect2: ld returned 1 exit status,　　make[1]: *** [objs/nginx] Error 1,　　make[1]: Leaving directory `/root/lnmp/src/nginx-1.4.2,　　make: *** [build] Error 2,　　解决方法：,　　./configure 后面加上–with-cc-opt=’-DLINUX=2 -D_REENTRANT -D_LARGEFILE64_SOURCE -march=i686 -pthread’ ，如下：,　　# make clean,　　# ./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --add-module=../ngx_pagespeed-release-1.6.29.5-beta,　　--with-cc-opt=-DLINUX=2 -D_REENTRANT -D_LARGEFILE64_SOURCE -march=i686 -pthread,　　# make,　　# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx$(date +%m%d) #备份nginx原文件,　　# cp objs/nginx /usr/local/nginx/sbin/nginx #复制编译make后的文件覆盖nginx原文件,　　# /usr/local/nginx/sbin/nginx -t #检测nginx配置文件语法是否正确,　　nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok,　　nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful,　　# kill -USR2 `cat /usr/local/nginx/logs/nginx.pid` #把nginx.pid改成nginx.pid.oldbin跟着启动新的nginx,　　# kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin` #退出旧的nignx,　　使用ngx_pagespeed,　　# mkdir /var/ngx_pagespeed_cache,　　# chown www.www /var/ngx_pagespeed_cache,　　# cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf$(date +%m%d) #备份nginx配置文件,　　# vi /usr/local/nginx/conf/nginx.conf,　　server {,　　#省略,　　pagespeed on;,　　pagespeed FileCachePath /var/ngx_pagespeed_cache;,　　pagespeed RewriteLevel CoreFilters;,　　pagespeed EnableFilters local_storage_cache;,　　pagespeed EnableFilters collapse_whitespace,remove_comments;,　　pagespeed EnableFilters outline_css;,　　pagespeed EnableFilters flatten_css_imports;,　　pagespeed EnableFilters move_css_above_scripts;,　　pagespeed EnableFilters move_css_to_head;,　　pagespeed EnableFilters outline_javascript;,　　pagespeed EnableFilters combine_javascript;,　　pagespeed EnableFilters combine_css;,　　pagespeed EnableFilters rewrite_javascript;,　　pagespeed EnableFilters rewrite_css,sprite_images;,　　pagespeed EnableFilters rewrite_style_attributes;,　　pagespeed EnableFilters recompress_images;,　　pagespeed EnableFilters resize_images;,　　pagespeed EnableFilters convert_meta_tags;,　　location ~ ".pagespeed.([a-z].)?[a-z]{2}.[^.]{10}.[^.]+" { add_header "" "";
