一、前言🙊

今天给大家介绍一个 Web 应用程序平台，LAMP 架构，这个架构放在今天为止也是非常热门的架构。

这里我们将使用 shell 脚本实现具有以下三大功能： 👖

• 一键搭建 LAMP 环境
• 一键删除 LAMP 环境
• exit 退出脚本

shell 脚本细节： 👖

• 1、基础环境配置（前提条件）
• 2、安装 \ 卸载 apache （web 服务器）
• 3、安装 \ 卸载 mariadb （数据库）
• 4、安装 \ 卸载 php （计算机编程语言）
• 5、阶段成功信息写入 log 日志文件中（ lamp_success.log、lamp_error.log ）

ps：php 能直接嵌入 html 中，与 html 混编，目的主要是 web 开发人员快速编写动态生成的 web 页面。

二、脚本中方法说明 👑

这个脚本我们将创建7个方法

1、prerequisite（基础环境配置）

• 关闭和永久关闭防火墙、
• 关闭 SELINUX、
• 配置阿里 yum 源

2、install_apache（安装 apache 服务器）

• 判断 apache 是否安装
• 安装 apache
• 启动 apache
• 检测 apache 服务端口和服务状态
• curl 访问 apache

3、install_mariadb（安装 maraidb 数据库）

• 判断 maraidb 是否安装
• 安装 mariadb
• 启动 mariadb
• 检测 mariadb 服务端口和服务状态
• 初始化数据库
• 测试 mariadb 是否能使用

4、install_php（安装 php 环境）

• 判断 php 是否安装
• 安装 php
• 重新启动 httpd
• 判断 info.php 文件是否存在
• curl 访问 php

5、remove_lamp（删除 LAMP 环境）

• remove apache：判断是否安装 apache server、删除 http
• remove mariadb：判断是否安装 maraidb、删除 mariadb
• remove php：判断 php 是否安装、删除 php

6、lamp_log（创建日志文件）

• 判断 lamp 目录是否存在、创建 lamp 目录

7、main（脚本入口）

• 脚本使用说明
• 判断是否输入的是数字
• 判断用户输入的值是否匹配，安装，移除
• 依次调用上面的方法

三、LAMP shell源码 ✈

将阶段成功信息写入 log 日志文件中

• 1：代表标准输出
• 2：代表错误输出

下列方法是将 1 标准输出写入一个文件，2 错误输出写入一个文件 😾

1>>/var/log/lamp/lamp_success.log 2>>/var/log/lamp/lamp_error.log
