这篇文章主要介绍了Shell实现多级菜单系统安装脚本实例分享,本文脚本用多级菜单实现LAMP、LNMP安装展现效果,需要的朋友可以参考下：
提示：本脚本主要实现多级菜单效果，并没有安装LAMP、LNMP环境，如果要用在实际生成环境中部署LNMP、LAMP环境，只需要简单修改一下就可以了。
演示效果：
1、一级菜单
2、二级菜单
3、执行操作
脚本参考：
| 代码如下： |
#!/bin/bash
#
[ -f /etc/init.d/functions ] && . /etc/init.d/functions
function menu(){
cat << EOF
----------------------------------------------
|*******Please Enter Your Choice:[1-4]*******|

* `echo -e "\033[35m 3)quit\033[0m"`
* `echo -e "\033[35m 4)return main menu\033[0m"`
EOF
}
