Write a Shell script to monitor the running status of the jar

1. Create a shell file and edit the content as follows

#!/bin/bash
port=10009 
jar_name=/home/data/myqxin/hpmis-0.0.1-SNAPSHOT.jar

#运行脚本提示信息
tips(){
    
    
 echo "------------------"
 echo ""
 echo "服务器端口：${port}"
 echo "jar包路径：${jar_name}"
 echo ""
 echo "可执行命令参数"
 echo "-status -查看当前服务运行状态"
 echo "-start -启动服务"
 echo "-stop -停止服务"
 echo "-restart -重启服务"
 echo ""
 echo "------------------"
}

#查询状态
status(){
    
    
  #查询端口的PID {print $7{取出打印的第7个值
  pid=$(netstat -nlp |grep :$port | awk '{print $7}' | awk -F"/" '{ print $1 }')
  #判断端口是否被占用
  if [ -z "${pid}" ];then
	echo "没有项目在运行"
  else
  	echo "项目正在运行"	  
  fi
}

#启动服务
start(){
    
    
  pid=$(netstat -nlp |grep :$port | awk '{print $7}' | awk -F"/" '{ print $1 }')
  if [ -z "${pid}" ];then
	echo "正在启动......"
	/home/data/jdk/bin/java -jar $jar_name --spring.profiles.active=test > log.log &
  else
	echo "项目运行中或端口已被占用"
  fi
}

#停止服务
stop(){
    
    
  pid=$(netstat -nlp |grep :$port | awk '{print $7}' | awk -F"/" '{ print $1 }')
  if [ -z "${pid}" ];then
	echo "没有项目正在运行，请先启动"
  else
	kill -9 $pid
	echo "已杀死端口为${port} 的应用"
  fi
}

#重启服务
restart(){
    
    
  pid=$(netstat -nlp |grep :$port | awk '{print &7}' | awk -F"/" '{ print $1 }')
  echo "正在杀死端口 ${port} 的pid ${pid} 中..."
  if [ -z "${pid}" ];then
	echo "服务未启动"
  else
 	kill -9 $pid
  fi
  sleep 5
  start
  echo "服务重启成功"
}

# 参数选项
case "$1" in
 "-status")
  status
  ;;
 "-start")
  start
  ;;
 "-stop")
  stop
  ;;
 "-restart")
  restart

  tips

esac

2. Give the script permission

chmod 777 xxx.sh

3. Execute the demo
