第十四周

1.简述CGI与FASTCGI区别

CGI

CGI: Common Gateway Interface 公共网关接口,为http服务器与其他机器上的程序服务通信交流的一种协议，CGI程序必须运行在网络服务器上，以前web服务器一般只处理静态的请求，如果要处理动态请求，web服务器根据请求的内容，会fork一个新的进程来运行外部C程序或者其他程序等，整个进程会把处理完的数据返回给web服务器，最后web服务器把内容发送给客户端，刚才fork的进程也随之退出。如果下次用户还请求是动态资源，那么web服务器又再次fork一个子进程，周而复始的进行,不适合高并发场景，效率极其低下。

CGI 可以让一个客户端，从网页浏览器通过http服务器向执行在网络服务器上的程序传输数据，CGI 描述了客户端和服务器程序之间的传输的一种标准

请求流程:
client -->(httpd协议)-->httpd--(cgi协议)-->application server(program file)--(mysql协议)-->mysql

fastcgi

fastcgi 的方式是，web服务器收到一个请求时，不会重新 fork 一个进程(因为整个进程在web服务启动时就开启了，而且不会退出)，web服务器直接把内容传递给整个进程(进程间通信，但fastcgi使用了别的方式，tcp方式通信)，这个进程收到请求后进行处理，把结果返回给web服务器，最后自己接着等待下一个请求的到来，而不是退出
fastcgi 是一个可伸缩地，高速地在 http服务器和动态脚本语言间通信的接口(在linux 下 fastCGI接口即为 socket ，整个socket 可以是文件 socket 也可以是iP socket),主要优点就是把动态语言和http服务器分离开来。多数流行的http服务器都支持fastCGI，包括apache nginx 等。
同时,fastcgi也被许多脚本语言所支持，例如php.
fastcgi接口采用的是C/S架构，他可以将http服务器和脚本解析分开，同时还能在脚本解析服务器上启动一个或多个脚本来解析守护进程。当http服务器遇到童泰程序时，可以量其直接交付给 fastcgi进程来执行，然后将得到的结果返回给浏览器，这种方式可以让 http服务器专一地处理静态请求，或者将动态脚本服务器的结果返回给客户端，这在很大程度上提高了整个应用系统的性能.

#fastcgi的重要特点如下
http服务器和动态脚本语言间通信的接口或工具
可把动态语言解析和http服务器分开
nginx  apache 以及多数动态语言都支持 fastcgi
fastcgi 接口方式采用c/s结构，分为客户端(http服务器)和服务器端(动态语言解析服务器)
php动态语言服务器端可以启动多个 fastcgi的守护进程(php-fpm)
http服务器通过(nginx fastcgi_pass) fastcgi客户端和动态语言 fastcgi服务器端通信(php-fpm)

请求流程:
client--(http协议)-->httpd--(fastcgi 协议)-->fastcgi服务器--(mysql协议)--->mysql

CGI与fastcgi 比较

CGI:兼职，一次性的服务方式
fastCGI:专值，全周期的持续式的服务

名称	在web服务器方面	在对数据进行处理的进程方面
cgi	fork一个新的进程进程处理	读取参数、处理数据、然后就结束生命周期
fastcgi	用tcp方式跟远程机器上得进行或本地进程建立连接	要开启tcp端口、进入循环、等待数据的到来，处理数据

2.编译安装基于fastcgi模式的多虚拟主机的wordpress和discuz的LAMP/lnmp架构

0.环境要求

#wordpress discuz 开源php程序，用于博客、论坛
#可以采用lamp/lnmp架构
#以下采用 lamp 架构

需要服务器2台:
node00 192.168.80.100 数据库服务器
caserver 192.168.80.111 httpd+php(fastcgi模式)服务器

3.通过loganalyzer展示数据库中的日志

0.环境需求

#三台主机
一台日志服务器 192.168.80.103  centos8
一台数据库服务器 192.168.80.100 直接利用上面的案例环境
一台http+php服务器，并安装loganalyzer展示web图形 192.168.80.111 直接利用上面的案例环境

通过loganalyzer 展示数据库中的日志

rsyslog武器----->mysql服务器----->httpd+php服务器

loganalyzer是用 php 语言实现的日志管理系统，可将MySQL数据库的日志用丰富的WEB方式进行展示
