1、简介
      使用shell脚本安装lnmp，纯粹是偷懒，平时安装一些东西都写成脚本了，方便以后在其他机器安装的时候不用再去查找文档。

　　PHP版本5.6.6

　　MYSQL版本5.6.26

　　NGINX版本1.15.6

2、环境说明
　  阿里云ECS（1G1核）CentOS 7.4 64位

3、shell脚本

4、开始安装
　　
上面上个文件放在同一目录并都给予执行(x)权限

在shell目录执行 sh cnl_install_lnmp.sh

输入 Y 确认执行安装，需要安装的安装包会自己检查，本人在自己的几台服务器都测试过，安装正常。

安装完会自己加到系统服务 ，并启动。
