LAMP(Linux+Apache+MySQL+PHP)环境介绍、配置、搭建
LAMP介绍
LAMP是由Linux， Apache， MySQL， PHP组成的，即把Apache、MySQL以及PHP安装在Linux系统上，组成一个环境来运行PHP的脚本语言。Apache是最常用的Web服务软件，而MySQL是比较小型的数据库软件。三个角色可以安装在一台机器上，也可以分开（但httpd和php要在一起的）
为什么需要LAMP?
手动逐个编译安装各个组件，需要输入各种命令，且有可能会中途出错。
对于想要成功搭建 LAMP 建站环境来说，可以节约大量时间和精力。
LAMP 有什么优点？
LAMP 是最经典的建站环境之一，风靡世界十几年。
而本脚本只需几个简单交互，选择需要安装的包，即可一路安装，无人值守。
准备工作

MySQL介绍
MySQL是一个关系型数据库，由mysql ab公司开发，mysql在2008年被sun公司收购（10亿刀），2009年sun公司被oracle公司收购（74亿刀）
MySQL官网https://www.mysql.com 最新版本5.7GA/8.0DMR
MySQL5.6变化比较大，5.7性能上有很大提升
