lamp介绍和部署流程
lamp简介
-
lamp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。
-
LAMP指的是Linux（操作系统）、Apache（HTTP服务器）、MySQL（也指MariaDB，数据库软件）和PHP（有时也是指Perl或Python）的第一个字母，一般用来建立web应用平台。
web服务器工作流程
web服务器
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
web工作流程
- 客户端通过http协议请求web服务器资源
- web服务器收到请求后判断客户端请求的资源是静态资源或是动态资源
- 若是静态资源则直接从本地文件系统取之返回给客户端。
- 否则若为动态资源则通过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。
lamp平台构建
环境说明：
| 系统平台 | IP | 需要安装的服务 |
|---|---|---|
| redhat8 | 192.168.110.133 | httpd-2.4 mysql-5.7 php php-mysql |
lamp平台软件安装次序：
