  • 4. lamp自动安装脚本

    • 1. 概述

    什么是LAMP？

    • 所谓的lamp，是由
      Linux、Apache、MySQL/MariaDB、PHP/Perl/Python
      组成的一个动态网站或者服务器的开源软件
    • 除Linux外其它各部件本身都是各自独立的程序，可以安装在不同服务器之上，但是因为经常被放在一起使用，拥有了越来越高的兼容度，共同组成了一个强大的Web应用程序平台。

    各服务提供什么功能？

    • Apache 处理http的请求、构建响应报文等自身服务
    • 配置让Apache支持PHP程序的响应（通过PHP模块或FPM）
    • 配置Apache具体处理php程序的方法，如通过反向代理将php程序交给fcgi处理
  • PHP/Perl/Python
      提供apache的访问接口，即CGI或Fast CGI
    • 提供PHP程序的解释器
    • 提供mairadb数据库的连接函数的基本环境
  • MySQL/MariaDB
      提供PHP程序对数据的存储
    • 提供PHP程序对数据的读取

    2. web服务器工作流程

    如上图所示：

    1. 用户在浏览器上访问资源，浏览器通过http协议向web服务器发送访问请求
    2. 如果访问的是静态资源，则会在本地磁盘或本地缓存中找到资源然后返还给浏览器
    3. 如果访问的是动态资源，web服务器则会通过FastCGI协议向php服务器发送请求
    4. php服务器会通过FastCGI master进程，让多个FastCGI worker进程处理请求，然后将处理后的输出返还给web服务器，最后由web服务器返还给浏览器
    5. 如果web服务器请求的资源，需要查询数据库，则php服务器上的php程序通过mysql协议连接数据库，并查询资源，php服务器将查询到的资源返还给web服务器，最后web服务器将资源返还给浏览器

    什么是静态资源，什么是动态资源？

    • 静态资源就是指静态内容，客户端从服务器获得的资源的表现形式与原文件相同。可以简单的理解为就是直接存储于文件系统中的资源
    • 动态资源通常是程序文件，不是将程序文件直接返还给客户端，而是需要将程序执行后输出的结果返还给客户端，输出的结果就是动态资源

    cgi与fastcgi是什么？

    • CGI（Common Gateway Interface）通用网关接口 是一种让web服务器与应用程序进行通信的协议，用来规范web服务器传输到php解释器中的数据类型以及数据格式
    • CGI可以用任何一种具有标准输入、输出和环境变量的语言编写，如php、perl、python等，不同类型语言写的程序只要符合cgi标准，就能作为一个cgi程序与web服务器交互
  • FastCGI（Fast Common Gateway Interface）快速通用网关接口
      通用网关接口（CGI）的增强版本，主要用来提高CGI程序性能，类似于CGI，FastCGI也是一种让交互程序与Web服务器通信的协议
    • CGI是通过启用一个解释器进程来处理每个请求，耗时且耗资源，而FastCGI则是通过master-worker形式来处理每个请求
    • 启动一个master主进程，然后根据配置启动几个worker进程，当请求进来时，master会从worker进程中选择一个去处理请求，这样就避免了重复的生成和杀死进程带来的频繁cpu上下文切换而导致耗时

    httpd与php结合的方式：

    • modules：php将以httpd的扩展模块形式存在，需要加载动态资源时，httpd可以直接通过php模块来加工资源并返回给客户端 httpd prefork：libphp5.so（多进程模型的php）
    • httpd event or worker：libphp5-zts.so（线程模型的php）
  • CGI：httpd需要加载动态资源时，通过CGI与php解释器联系，获得php执行的结果，此时httpd负责与php连接的建立和断开等
  • FastCGI：利用php-fpm机制，启动为服务进程，php自行运行为一个服务，https通过socket与php通信

    • 3. LAMP平台搭建实例
