企业级LNMP自动化批量部署

一、LNMP简介

  1）LNMP是目前互联网主流的WEB服务器架构，主要是由Linux+Nginx+MYSQL|Mariadb+PHP组合，可以发布企业门户网站代码（PHP动态网页），运维人员需要能够独立构建LNMP平台。
  2）基于手工MAKE源码方式构建LNMP WEB平台，操作步骤、指令非常的繁琐，如果企业要求快速、高效的配置平台，通过手工操作会消耗大量的人力成本，可以引入SHELL编程自动化实现。

• Nginx官网下载Nginx软件包&解压&编译&安装；
• MYSQL官网下载MYSQL软件包&解压&编译&安装；
• PHP官网下载PHP软件包&解压&编译&安装；
• LNMP配置文件整合，创建PHPinfo测试页面&访问

二、shell代码实现

环境准备：

• Linux系统：Centos7
• 网卡：能够联通互联网（即 ping通www.baidu.com）
• 建议：运行前关闭防火墙和Selinux，防止网站端口被防火墙关闭
