LNMP架构服务一键部署

之前的博客中有介绍过LAMP的架构，而LNMP和LAMP的区别就在于使用Nginx而不是Apache。

LNMP是Linux+Nginx+Mysql+PHP的组合方式，其特点是利用Nginx的快速与轻量级，替代以前的LAMP的方式，由于安装方便，并且安装脚本也随时更新。

LNMP的优点在于：占用VPS资源较少，Nginx配置起来也比较简单方便，利用fast-cgi的方式动态解析PHP脚本。

LNMP的缺点也同样很明显：php-fpm组件的负载能力优先，在访问量巨大的时候，php-fpm进程容易僵死，容易发生502bad gateway的错误。

下面是我写的一键部署LNMP的脚本 

首先需要准备一台环境干净的虚拟机   环境不干净在执行的过程中会出现各种各样的报错

然后将虚拟机联网 并下载好所需安装包   需要注意的几点（1.我使用的安装包的版本  2.我的虚拟机给的是4核4线程 如果给的资源不够在编译安装的过程中也会报错 3.我给的运存是8G ）
