1.如何关闭ES，elasticsearch关闭办法
1.使用head插件
找到想关掉的节点进行关停
2.使用命令kill杀掉服务器的ES进程即可
1.查找ES进程
ps -ef | grep elastic
2.杀掉ES进程
kill -9 2382（进程号）
3.重启ES
sh elasticsearch -d
2.如何重启ES
没有重启的办法，只有参考上面关闭->开启这样。
以下是详细的操作过程
1.首先是查找服务器是否有ES进程，无果ES没有开启，也就不用关闭了，如果开启，则杀死进程就行
1.查找进程命令 ps -ef | grep elastic
[root@bjdhj-125-203 _site]# ps -ef | grep elastic
//然后可以看到如下的进程号，2382,2583之类的，之后kill掉就可以啦。
