我的Ubuntu Server脚本工具【1】

无论是自己的兴趣还是与工作需求，经常需要在Ubuntu Server上安装LAMPP，于是乎自己编写了自己需要的安装脚本，主要功能如下：

1）安装到指定目录，默认安装到/opt/lampp

2）支持多个版本，使用符号链接

3）添加自启动脚本

代码如下：

查看代码

  1 #Install lampp

  2 # parameters:

  3 # $1: mandatory, install package

  4 # $2: mandatory, lampp version, ex. 1.8.1

  5 # $3: optional, target folder, default is /opt/lampp

  6 

  7 # date

  8 year=`date +%Y`

  9 month=`date +%m`

 10 day=`date +%d`

 11 today=$year-$month-$day
