使用ngx_pagespeed模块给Nginx加速

为了优化一下 http/1.1 的速度，尝试一下这个模块

首先你必须已经升级了 gcc，可以看上一篇文章

下面来看看怎么用，nginx 的模块都需要静态编译，我们只有重新编译源码

[root@centos soft]# cd /tmp/soft
[root@centos soft]# NPS_VERSION=1.11.33.0
[root@centos soft]# wget https://github.com/pagespeed/ngx_pagespeed/archive/release-${NPS_VERSION}-beta.zip -O release-${NPS_VERSION}-beta.zip
[root@centos soft]# unzip release-${NPS_VERSION}-beta.zip
[root@centos ngx_pagespeed-release-1.11.33.0-beta]# cd ngx_pagespeed-release-${NPS_VERSION}-beta/
[root@centos ngx_pagespeed-release-1.11.33.0-beta]# wget https://dl.google.com/dl/page-speed/psol/${NPS_VERSION}.tar.gz #这是谷歌的PageSpeed优化库
[root@centos ngx_pagespeed-release-1.11.33.0-beta]# tar -xzvf ${NPS_VERSION}.tar.gz  # extracts to psol/
[root@centos ngx_pagespeed-release-1.11.33.0-beta]# /usr/local/nginx/sbin/nginx -V
nginx version: weicn-server/1.0
built by gcc 4.8.2 20140120 (Red Hat 4.8.2-15) (GCC)
built with OpenSSL 1.0.2g  1 Mar 2016
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --with-http_ssl_module --with-http_v2_module --with-openssl=/tmp/soft/openssl-1.0.2g --with-http_sub_module --with-http_stub_status_module --with-pcre --with-pcre=/tmp/soft/pcre-8.33 --with-zlib=/tmp/soft/zlib-1.2.8 --with-http_secure_link_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-ld-opt=-ljemalloc --add-module=/tmp/soft/nginx-ct-1.0.0
[root@centos ngx_pagespeed-release-1.11.33.0-beta]# cd /tmp/soft/nginx-1.9.13
[root@centos nginx-1.9.13]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_v2_module --with-openssl=/tmp/soft/openssl-1.0.2g --with-http_sub_module --with-http_stub_status_module --with-pcre --with-pcre=/tmp/soft/pcre-8.33 --with-zlib=/tmp/soft/zlib-1.2.8 --with-http_secure_link_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-ld-opt=-ljemalloc --add-module=/tmp/soft/nginx-ct-1.0.0 --add-module=/tmp/soct/ngx_pagespeed-release-${NPS_VERSION}-beta
[root@centos nginx-1.9.13]# make
[root@centos nginx-1.9.13]# mv /usr/local/nginx/sbin/nginx{,_`date +%F`}
[root@centos nginx-1.9.13]# cp objs/nginx /usr/local/nginx/sbin

然后配置 conf

server {
    # 侦听的端口
    listen 80;
    # 服务器名称
    server_name cuojue.org;
    # 记下根目录
    root /usr/local/nginx/html;
    # 访问日志
    access_log /var/log/nginx/access.log main;
    # 启用ngx_pagespeed
    pagespeed on;
    # 在此放置一个或多个pagespeed过滤器。
}

说到指定 PageSpeed 过滤器，有两种不同的级别可供你选择：CoreFilters 和 PassThrough。除非有所指定，否则默认情况下使用 CoreFilters。

server {
    # 侦听的端口
    listen 80;
    # 服务器名称
    server_name cuojue.org;
    # 记下根目录
    root /usr/local/nginx/html;
    # 访问日志
    access_log /var/log/nginx/access.log main;
    # 启用ngx_pagespeed
    pagespeed on;
    pagespeed FileCachePath /var/ngx_pagespeed_cache;
    # 禁用CoreFilters
    pagespeed RewriteLevel PassThrough;
    # 启用压缩空白过滤器
    pagespeed EnableFilters collapse_whitespace;
    # 启用JavaScript库卸载
    pagespeed EnableFilters canonicalize_javascript_libraries;
    # 把多个CSS文件合并成一个CSS文件
    pagespeed EnableFilters combine_css;
    # 把多个JavaScript文件合并成一个JavaScript文件
    pagespeed EnableFilters combine_javascript;
    # 删除带默认属性的标签
    pagespeed EnableFilters elide_attributes;
    # 改善资源的可缓存性
    pagespeed EnableFilters extend_cache;
    # 更换被导入文件的@import，精简CSS文件
    pagespeed EnableFilters flatten_css_imports;
    pagespeed CssFlattenMaxBytes 5120;
    # 延时加载客户端看不见的图片
    pagespeed EnableFilters lazyload_images;
    # 启用JavaScript缩小机制
    pagespeed EnableFilters rewrite_javascript;
    # 启用图片优化机制
    pagespeed EnableFilters rewrite_images;
    # 预解析DNS查询
    pagespeed EnableFilters insert_dns_prefetch;
    # 重写CSS，首先加载渲染页面的CSS规则
    pagespeed EnableFilters prioritize_critical_css;
}

创建将由 Nginx 写入的一个文件缓存目录。

[root@centos nginx-1.9.13]# mkdir /var/ngx_pagespeed_cache
[root@centos nginx-1.9.13]# chown www:www /var/ngx_pagespeed_cache

好了，重启一下 Nginx
