Nginx下安裝配置PageSpeed模塊，輕鬆完成網站提速

做爲Nginx組件，ngx_pagespeed將重寫你的網頁，讓用戶以更快的速度進行訪問。重寫的工做包括壓縮圖片、縮減CSS和JavaScript、擴展緩存時間，一樣還包括其它一些最佳實踐：

• 優化緩存——整合應用程序的數據和邏輯
• 最小化round-trip次數——削減連續的請求/響應週期數
• 最小化請求開銷——削減上傳大小
• 最小化負載大小——削減響應、下載及緩存頁面大小
• 優化瀏覽器渲染——改善瀏覽器頁面佈局
• 移動方面的優化——優化站點移動網絡和設備方面的相關特性

下載解壓PageSpeed模塊

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/

查看線上版本編譯參數

# /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

增長ngx_pagespeed模塊從新編譯

# 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) #備份nginx原文件 # cp objs/nginx /usr/local/nginx/sbin/nginx #複製編譯make後的文件覆蓋nginx原文件 # /usr/local/nginx/sbin/nginx -t #檢測nginx配置文件語法是否正確 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改爲nginx.pid.oldbin跟着啓動新的nginx # kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin` #退出舊的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$(date +%m%d) #備份nginx配置文件
# vi /usr/local/nginx/conf/nginx.conf
server {
pagespeed on; #這2行建議放在給個server內，若是放在全局,測試discuz不能用？
pagespeed FileCachePath /var/ngx_pagespeed_cache;
location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" { add_header "" ""; }
location ~ "^/ngx_pagespeed_static/" { }
location ~ "^/ngx_pagespeed_beacon$" { }
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
