Pagespeed可以通过前后端优化加速网站载入速度。

最新编译步骤

sudo apt-get install build-essential zlib1g-dev libpcre3 libpcre3-dev unzip

mkdir nginx && cd nginx
NPS_VERSION=1.9.32.4
wget https://github.com/pagespeed/ngx_pagespeed/archive/release-${NPS_VERSION}-beta.zip
unzip release-${NPS_VERSION}-beta.zip
cd ngx_pagespeed-release-${NPS_VERSION}-beta/
wget https://dl.google.com/dl/page-speed/psol/${NPS_VERSION}.tar.gz
tar -xzvf ${NPS_VERSION}.tar.gz

cd ..
NGINX_VERSION=1.8.0
wget http://nginx.org/download/nginx-${NGINX_VERSION}.tar.gz
tar -xvzf nginx-${NGINX_VERSION}.tar.gz
cd nginx-${NGINX_VERSION}/

make
sudo make install

先建立缓存文件夹：

sudo mkdir /var/ngx_pagespeed_cache

最高优化配置：

http {
    ##
    #ngx_pagespeed module settings
    ##
    pagespeed on;
    pagespeed FileCachePath /var/ngx_pagespeed_cache;
    pagespeed FileCacheSizeKb            102400;
    pagespeed FileCacheCleanIntervalMs   3600000;
    pagespeed FileCacheInodeLimit        500000;
    #pagespeed LRUCacheKbPerProcess     8192;
    #pagespeed LRUCacheByteLimit        16384;
