之前使用jar包发布springboot服务时，每次启动都要敲一串命令，每次停止服务的时候还要找到这个服务kill掉，非常的麻烦。为了提高管理的效率，专门查阅了Linux的一些资料，写了一个shell service.sh 脚本，效果还不错。

#!/bin/bash
OUTPUT_FILE="console.log"
PID_FILE="service.pid"
SERVICE_OPTS="" #-cp . -Xmx128m -Xms128m
SERVICE_JAR="demo.jar"
SERVICE_PORT="10000"
SERVICE_IP="192.168.1.232"

# setting jmx
if [ "$1" = "jmx" ]; then
  SERVICE_OPTS="${SERVICE_OPTS} -Dcom.sun.management.jmxremote \
  -Dcom.sun.management.jmxremote.port=${SERVICE_PORT} \
  -Djava.rmi.server.hostname=${SERVICE_IP} \
  -Dcom.sun.managent.jmxremote.authenticate=true \
  -Dcom.sun.management.jmxremote.ssl=false "
  shift
fi

# start the service
if [ "$1" = "start" ]; then
  # According to pid judge whether the program is still running
  if [ -n "${PID_FILE}" ] && [ -f ${PID_FILE} ]; then
    if [ -s ${PID_FILE} ] && [ -r ${PID_FILE} ]; then
      servicePid=`cat ${PID_FILE}`
      ps -p ${servicePid} &> /dev/null
      if [ $? -eq 0 ]; then
        echo "Service appears to still be running with PID ${servicePid}. Start aborted."
        echo "If the following process is not a service process, remove the PID file and try again:"
        ps -f -p ${servicePid}
        exit 1
      else
        cat /dev/null > ${PID_FILE}
        if [ $? -ne 0 ]; then
          echo "Unable to clear stale PID file. Start aborted."
        fi
      fi
    fi
  fi

  # start the program and write pid to the file
  if [ -n "${SERVICE_JAR}" ] && [ -f ${SERVICE_JAR} ]; then
    nohup java ${SERVICE_OPTS} -jar ${SERVICE_JAR} >> ${OUTPUT_FILE} 2>&1 &
    echo $! > ${PID_FILE}
    if [ -s ${PID_FILE} ]; then
      echo "Service has been started."
      exit 0
    else
      echo "Sorry,service start failed."
      exit 1
    fi
  else
    echo "The \$SERVICE_JAR is not set or The jar file does not exist.Start aborted."
    exit 1
  fi

# stop the service
elif [ "$1" = "stop" ]; then
  #According to pid judge whether the program is running
  if [ -n "${PID_FILE}" ]; then
    if [ -f ${PID_FILE} ]; then
      if [ -s ${PID_FILE} ] && [ -r ${PID_FILE} ]; then
        servicePid=`cat ${PID_FILE}`
        ps -p ${servicePid} &> /dev/null
        if [ $? -eq 0 ]; then
          kill -9 ${servicePid} &> /dev/null
          if [ $? -ne 0 ]; then
            echo "Kill process failed. Stop aborted."
            exit 1
          fi
          echo "The Service process has stopped."

          # remove pid file
          rm -f ${PID_FILE} &> /dev/null
          if [ $? -ne 0 ]; then
            echo "The ${PID_FILE} removal failed."
            exit 1
          else
            echo "The ${PID_FILE} has been removed."
            exit 0
          fi
        else
          echo "PID file found but no matching process was found. Stop aborted."
          exit 1
        fi
      else
       echo "PID file is empty or can't read the file.Stop aborted."
       exit 1
      fi
    else
      echo "\$SERVICE_PID was set but the specified file does not exist. Is service running? Stop aborted."
      exit 1
    fi
  else
    echo "\$SERVICE_PID is not set.Stop aborted."
    exit 1
  fi
else
  echo "Usage: service.sh ( commands ... )"
  echo "commands:"
  echo "  jmx start         Start Service under jmx control"
  echo "  start             Start Service"
  echo "  stop              Stop Service"
  exit 1
fi

根据个人需要填写service.sh脚本头部的参数信息，然后直接运行即可，如下：

• 启动服务：./service.sh start
• 停止服务: ./service.sh stop
• 开启jmx监控：./service.sh jmx start

如果需要开启jmx远程监控，需要修改jmxremote.access和jmxremote.password，前者用于配置访问权限，后者用于设置密码。这两个文件的默认位置在处于jre的 /lib/management/目录下。如果需要更改位置，可以在service.sh增加参数：

if [ "$1" = "jmx" ]; then
  SERVICE_OPTS="${SERVICE_OPTS} -Dcom.sun.management.jmxremote \
  -Dcom.sun.management.jmxremote.port=${SERVICE_PORT} \
  -Djava.rmi.server.hostname=${SERVICE_IP} \
  -Dcom.sun.managent.jmxremote.authenticate=true \
  -Dcom.sun.management.jmxremote.ssl=false \ 
  -Dcom.sun.management.jmxremote.acccess.file=/opt/jmxremote.access \
  -Dcom.sun.management.jmxremote.password.file=/opt/jmxremote.password"
  shift
fi

需要注意的是，这两个文件的权限需要进行调整：

chmod 600 jmxremote.access
chmod 600 jmxremote.password
