1、 Nginx ngx_pagespeed 模块安装配置1. 概述ngx_pagespeed 是一个 Nginx 的扩展模块，可以加速你的网站，减少页面加载时间，它会自动将一些提升 web 性能的实践应用到网页和相关的资源（CSS、JS 和图片）上，无需你修改内容和流程。功能包括：图片优化: stripping meta-data, dynamic resizing, recompression,CSS & JavaScript 压缩、合并等 ;小资源的内联,推迟图片和 JS 的加载;HTML 重写,延长缓存扩展。2. 部署2.1 环境准备1.关闭 iptables 和 SELINUX# ser

6、gespeed 的配置内容写入到 ngx_pagespeed.inc 中，在 nginx 的配置文件中 include 这个配置文件就可。pagespeed on; pagespeed RewriteLevel CoreFilters;pagespeed Domain *; #pagespeed TrackOriginalContentLength on; pagespeed SharedMemoryLocks on; #pagespeed FetchWithGzip on; pagespeed CustomFetchHeader Accept-Encoding gzip; pagespeed
7、 FileCachePath /fgn/cache/ngx_pagespeed_cache; pagespeed MemcachedThreads 1; #pagespeed MemcachedServers 127.0.0.1:11211; pagespeed FetcherTimeoutMs 4000; pagespeed RewriteDeadlinePerFlushMs 10; pagespeed FileCacheSizeKb 102400; pagespeed FileCacheCleanIntervalMs 1800000; pagespeed LRUCacheKbPerProc

10、peed 模块了。Nginx 可以编写启动脚本，将脚本复制到/etc/init.d/目录下就可以使用service 服务了。# vi /etc/init.d/nginx#!/bin/sh# nginx - this script starts and stops the nginx daemin# chkconfig: - 85 15# description: Nginx is an HTTP(S) server, HTTP(S) reverse # proxy and IMAP/POP3 proxy server# processname: nginx# config: /usr/loca
