把可运行jar转换成Linux服务运行

把下面代码复制到单独文件里，取名为【my-java-program】，用root用户将其复制到【/etc/init.d/】目录。
当然也可以最开始就在【/etc/init.d/】目录创建【my-java-program】文件。

【my-java-program】是自定义的内容，可根据需求自行修改。
启动：# /etc/init.d/my-java-program start
停止：# /etc/init.d/my-java-program stop
重启：# /etc/init.d/my-java-program reload

代码中【/path/to/my/java/program.jar】指可运行jar包的Full Path。
改【my-java-program】时要改全。
