Nginx安装配置PageSpeed模块实现网站加速

来源:本站整理 作者:梦在深巷 时间:2014-09-19 20:15:42

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

location /ngx_pagespeed_message { allow 127.0.0.1; deny all; }

#省略

}

# /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")

Setting option from ("FileCachePath", "/var/ngx_pagespeed_cache") [ OK ]

# curl -I 'http://www.linuxeye.com/' | grep X-Page-Speed

% Total % Received % Xferd Average Speed Time Time Time Current

Dload Upload Total Spent Left Speed

0 0 0 0 0 0 0 0 --:--:-- 0:00:03 --:--:-- 0

X-Page-Speed: 1.4.0.0-2748

注意:

如果discuz使用了伪静态要注销掉下面部分(前面加#注销):

#if (!-e $request_filename) {

# return 404;

#}

使用后效果如下:
