篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了写一个service 启动停止你的微服务的命令吧相关的知识，希望对你有一定的参考价值。

　　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。
