Nginx Pagespeed 配置

发表于 | 分类于 | | 阅读次数: | 字数统计: 533

Nginx服务器，可以安装ngx_pagespeed扩展，这样你的服务器下面的网站就可以自动通过pagespeed优化。网站返回的源码数据是经过pagespeed处理过的，比如处自动压缩css、html、javascript，图片自动压缩及处理为更小的格式webp。

同时包含一些最佳实践：

  • 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

网站配置

你可以在nginx.conf中全局配置，也可以针对某个网站进行配置，放在虚拟主机配置server中
