无意中翻出了几年前写的shell脚本。当时，测试环境有好几套，而且每套环境又是分布式+负载均衡+热备，全部由测试部维护和管理的。
当时，测试部就几个人，手动部署耗费人力不说，且经常出错。作为部门老大，亲力亲为的实现了测试环境自动化部署解决方案，这些脚本不但让测试部受益，让奋斗在前线的技术支持也成为受益者。
由于时间久远，开发和调试都是基于当时的系统版本完成的。
考虑到公司隐私，本文只开放部分基础环境的自动安装。

需求背景

• 自动识别当前系统，实行相应的环境变量配置方案
• 支持mysql（二进制包）、tomcat（二进制包）、jdk（rpm包）等基础环境的全新安装、覆盖安装、卸载
• tomcat支持配置堆内存和永久保留区大小
