#!/bin/bash
 
APPHOME="/home/work/elasticsearch"
PID=$(cat ${
     
     APPHOME}/elasticsearch.pid)
case $1 in
          start)
  ${APPHOME}/bin/elasticsearch > /dev/null  2>&1 &
 echo "$!" > ${APPHOME}/elasticsearch.pid
 
     ;;
          stop)
echo $PID|xargs kill -9
              ;;
          status)
              ps -ef |grep   $PID
              ;;
          restart)
 echo $PID|xargs kill -9
 ${APPHOME}/bin/elasticsearch > /dev/null  2>&1 &
 echo "$!" > ${APPHOME}/elasticsearch.pid
              ;;
          *)
              echo "require start|stop|status|restart"
