Linux自定义java程序运行脚本的命令

以下脚本将启动mes-lastest.jar，并且：

1、开启远程调试支持，端口8899，

2、开启GC日志记录功能

3、程序发送OOM是Dump内存

用法如下：

Usage: ./run.sh {start|stop|restart|status|stop -f}
Example: ./run.sh start

示例：

ubuntu@ubuntu:~$ ^C
ubuntu@ubuntu:~$ vim run.sh
ubuntu@ubuntu:~$ ./run.sh start
Maybe mes-lastest.jar is running, please check it...
ubuntu@ubuntu:~$ ./run.sh stop
The mes-lastest.jar is stopping...
ubuntu@ubuntu:~$ ./run.sh start
The mes-lastest.jar is starting...
ubuntu@ubuntu:~$

 

 

#!/bin/bash

    echo "Please check that this script and your jar-package is in the same directory!"
    exit 1
