作為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。重寫的工作包括壓縮圖片、縮減CSS和JavaScript、擴展緩存時間，同樣還包括其它一些最佳實踐：

下載解壓PageSpeed模塊
cd /root/lnmp/source wget https://github.com/pagespeed/ngx_pagespeed/archive/release-1.6.29.3-beta.zip unzip -q release-1.6.29.3-beta wget https://dl.google.com/dl/page-speed/psol/1.6.29.3.tar.gz tar xzf 1.6.29.3.tar.gz -C ngx_pagespeed-release-1.6.29.3-beta
查看線上版本編譯參數
# /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模塊重新編譯
# 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-1.6.29.3-beta/ # make //注意只make 不要make install (如果報錯請看下面)
安裝ngx_pagespeed (make) 可能會報如下錯誤
../ngx_pagespeed-release-1.6.29.3-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/source/nginx-1.4.2/../ngx_pagespeed-release-1.6.29.3-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/source/nginx-1.4.2' make: *** [build] Error 2
解決方法：
./configure 後面加上–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-1.6.29.3-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$(date +%m%d) #備份nginx原文件 # cp objs/nginx /usr/local/nginx/sbin/nginx #復制編譯make後的文件覆蓋nginx原文件 # /usr/local/nginx/sbin/nginx -t #檢測nginx配置文件語法是否正確 nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful # kill -USR2 `cat /usr/local/nginx/logs/nginx.pid` #把nginx.pid改成nginx.pid.oldbin跟著啟動新的nginx # kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin` #退出舊的nignx
使用ngx_pagespeed
# mkdir /var/ngx_pagespeed_cache
# chown www.www /var/ngx_pagespeed_cache
# cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf$(date +%m%d) #備份nginx配置文件
# vi /usr/local/nginx/conf/nginx.conf
server {
pagespeed on;
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
Setting option from ("on")
Setting option from ("FileCachePath", "/var/ngx_pagespeed_cache")
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
# service nginx restart
Stopping nginx: [ OK ]
Starting nginx: Setting option from ("on")

注意：
如果discuz使用了偽靜態要注銷掉下面部分（前面加#注銷）：
#if (!-e $request_filename) {
# return 404;
#}
使用後效果如下：
