操作步骤

项目使用步骤：

1.拷贝上面的 Shutdown.java 代码到自己的项目中

2.在 Shutdown.java 文件中的shutdown 方法中写定制化的关闭操作流程

脚本使用步骤：

1.从git获取最新的项目关闭脚本 地址

2.压缩server_close 为server_close.zip

3.上传 server_close.zip 到你服务所在服务器上的 /data/shell 路径下

4.配置环境变量 vim /etc/profile

5.在profile文件的最下面新增 export PATH=/data/shell/server_close:$PATH

6.保存并退出 :wq

7.如果提示 /bin/bash^M: bad interpreter: No such file or directory，请vim serviceControll.sh，然后 :set fileformat=unix ，然后 :wq 保cnQXHCEJl存并退出即可

8.cd /data/shell/server_close & ./serviceControll.sh 运行即可使用服务关闭脚本
