shell脚本：一键安装LAMP、LNMP脚本

137次阅读

共计 8434 个字符，预计需要花费 22 分钟才能阅读完成。

历时三天边写边测试，终于完成目前最长代码的脚本，总共 253 行，在 2 台机器安装 LAMP，LNMP 都顺利通过，脚本可做为生产环境使用。

脚本需要注意的地方：
1：脚本适用于 CentOS 系统 6.5 以上，干净系统；如安装过其他环境需要修改脚本内容；
2：脚本适用于：apache 2.4.x 版本；MySQL5.5.x 以上版本；php5.5.x 以上版本；
3：mysql、php、apache、nginx 安装包事先要下载到 /usr/local/src 目录下，如名字不对需要更改脚本里的软件包名称；

脚本安装的版本为以下，如需其他名称，请自行修改软件安装包名称和对应的目录名即可；
httpd-2.4.7.tar.gz、mysql-5.6.25.tar.gz、nginx-1.6.2.tar.gz、php-5.6.8.tar.gz
4：脚本没有增加判断，设定的环境为干净系统；

脚本内容如下：

#!/bin/bash
