LNMP%E7%AE%80%E4%BB%8B">一.LNMP简介
1.含义
LNMP分贝指的是Linux、Nginx、Mysql、PHP首字母缩写，四者组合起来工作
2.工作原理
用户通过浏览器输入域名时首先访问的是nginx的web服务静态页面由nginx处理，“.php”的动态文件就会由nginx利用FastCGI（可伸缩、高速的在http服务器和脚本语言之间通信的接口，Linux下这个交口是socket，会把动态语言文件和http服务器分离开处理，让http服务器专心处理静态页面，自己将动态页面处理好返给http服务器）接口交给PHP引擎处理解析，若是还要读取数据库信息，则PHP又继续向mysql数据库发出请求，处理完成后再将数据返回给用户
