lamp介绍
其实就是由Linux+Apache+Mysql/MariaDB+Php/Perl/Python的一组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，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。
web服务器工作流程
web服务器的资源分为两种，静态资源和动态资源
-
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
-
动态资源则通常是程序文件，需要在服务器执行之后，将执行的结果返回给客户端
工作过程：当客户端请求是静态资源时，web服务器会直接把静态资源返回个客户端。
：动态资源则通过FastCGI协议与php服务器联系，通过CGI程序的master进程调度worker进程来执行程序以获得客户端请求的动态资源，并将执行的结果通过FastCGI协议返回给httpd服务器，httpd服务器收到php的执行结果后将其封装为http响应报文响应给客户端。在执行程序获取动态资源时若需要获得数据库中的资源时，由Php服务器通过mysql协议与MySQL/MariaDB服务器交互，取之而后返回给httpd，httpd将从php服务器收到的执行结果封装成http响应报文响应给客户端。
cgi与fastcgi
CGI（Common Gateway Interface，通用网关接口），CGI是外部应用程序（CGI程序）与WEB服务器之间的接口标准，是在CGI程序和Web服务器之间传递信息的过程。CGI规范允许Web服务器执行外部程序，并将它们的输出发送给Web浏览器，CGI将web的一组简单的静态超媒体文档变成一个完整的新的交互式媒体。
FastCGI（Fast Common Gateway Interface）是CGI的改良版，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，即启动一个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
