直接复制下面代码，需要改下你的ES端口，和启动位置。（第十行，和第十八行）  
因为启动位置写好了，所以你随便把这个脚本放在那里都可以

#!/bin/bash
    
    # kconfig: 2345 91 11
    
    # description: elasticsearch
    
    #定义变量
    
    PORT=9200
    
    NAME=elasticsearch
    
    ID=`ps -aux | grep "$NAME" | grep -v "grep" | awk '{print $2}'`
    
    CHECK_PORT=`netstat -tnlp|grep "$PORT"`
    
    ELASTICSEARCH_SERVER=/usr/local/elasticsearch-7.4.2/bin/elasticsearch
    
    RETAVL=0
    
    #检查shelk公共函数库是否存在，存在就加载
    FUNCTIONS_PATH=/etc/init.d/functions
    [ -f $FUNCTIONS_PATH ]&& source $FUNCTIONS_PATH
    
    #检查文件是否存在并可执行
    [ -x $ELASTICSEARCH_SERVER ]|| exit 0
    
    
    #定义函数
    #检查是否执行成功
    check(){ 
    	RETAVL=$?
    	if 
    		[[ "$RETAVL" = 0 ]];then
    		action "elasticsearch is $1" /bin/true
    	else
    		action "elasticsearch is $1" /bin/false	
    	fi
    }
    #启动服务
    start(){ 
    	if
    		[[ "$CHECK_PORT" != "" ]];then
    		echo "elasticsearch already running"
    	else
    	su - es <<!
    	
    		$ELASTICSEARCH_SERVER -d
    
    exit
    
    !
    		check Started				
    	fi
    }
    #停止服务
    stop(){ 
    	if
    		[[ "$CHECK_PORT" = "" ]];then
    		echo "elasticsearch is not running."
    	else
    		kill -9 $ID
    		check Stopped
    	fi
    }
    #重启服务
    
    restart(){ 
    	stop
    	sleep 2
    	start
    }
    
     
    #判断
    case "$1" in
    start)
    		start
    		;;
    stop)
    		stop
    		;;
    restart)
    		restart
    		;;
    *)
    		echo $"Usage:$0{start|stop|restart|help}"
    
    esac
    
    exit $RETAVL

2.增加脚本可执行权限

chmod +x elasticsearch.sh
