在这个微服务盛行的时代，docker获得了巨大的成功，因为我们需要在一台服务器装上N个服务。
本文不是想讨论如何使用docker，而是，在一台服务器安装了多个服务后，怎样启动方便的启动服务呢？
一、在tomcat的时代中，直接使用tomcat的启动停止命令，轻松搞定，（tomcat的启动脚本很有水平，贴上来学习下吧）

运行脚本：
service ser01 stop #启动 service ser01 start #停止 ps -ef | grep java #服务运行情况
shell 脚本确实很方便，虽然这会涉及到另一个专业领域的东西，但是自已使用一下也很安逸呢~
尤其在排查问题时， shell方面的知识往往会帮自己很大的忙。
想要将自己写的脚本添加到service命令中，只需将该脚本移动到 /etc/init.d/ 目录下，即可以使用 service xxx command 了。
