转载自：https://blog.csdn.net/weixin_43424356/article/details/106558710

将 Elastic Search 的启动命令写成一个服务文件 /etc/init.d/elasticsearch 即可。

#!/bin/sh
### BEGIN INIT INFO
# Provides:          elasticsearch
# Required-Start:    $all
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:
# Short-Description: The Elasticsearch starter.
### END INIT INFO
 
case "$1" in
start)
    su es<<!
    cd /home/es/elasticsearch
    ./bin/elasticsearch -d
!
    echo "elasticsearch startup"
    ;;  
stop)
    es_pid=`ps aux|grep elasticsearch | grep -v 'grep elasticsearch' | awk '{print $2}'`
    kill -9 $es_pid
    echo "elasticsearch stopped"
    ;;  
restart)
    es_pid=`ps aux|grep elasticsearch | grep -v 'grep elasticsearch' | awk '{print $2}'`
    kill -9 $es_pid
    echo "elasticsearch stopped"
    su es<<!
    cd /home/es/elasticsearch
    ./bin/elasticsearch -d
!
    echo "elasticsearch startup"
    ;;  
*)
    echo "start|stop|restart"
    ;;  
esac
 
exit $?

给予执行权限：

sudo chmod +x /etc/init.d/elasticsearch

将 ElasticSearch 设置开机启动：

chkconfig --add elasticsearch

Ubuntu 下：

sudo update-rc.d elasticsearch defaults		# Adding
systemctl enable elasticsearch.service

sudo update-rc.d -f elasticsearch remove 	# Removing

手动干预：

/etc/init.d/elasticsearch start
/etc/init.d/elasticsearch stop
/etc/init.d/elasticsearch restart

查看服务状态：

systemctl status elasticsearch.service
