LAMP 架构搭建
1. LAMP架构简介
所谓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。
2. 架构说明
apache主要实现如下功能:
第一:处理http的请求、构建响应报文等自身服务;
第二:配置让Apache支持PHP程序的响应(通过PHP模块或FPM);
第三: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。
mariadb主要实现如下功能:
第一:提供PHP程序对数据的存储;
第二:提供PHP程序对数据的读取(通常情况下从性能的角度考虑,尽量实现数据库的读写分离)。
php主要实现如下功能:
第一:提供apache的访问接口,即CGI或Fast CGI(FPM);
第二:提供PHP程序的解释器;
第三:提供mairadb数据库的连接函数的基本环境。
由此可知,要实现LAMP在配置每一个服务时,安装功能需求进行配置,即可实现LAMP的架构,当然apache、mariadb和php服务都可配置为独立服务,安装在不同服务器之上。
