SpringBoot服务管理shell脚本

    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.accessjmxremote.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
