ElasticSearch关闭重启命令
很多人学习elasticSearch都是自学,想百度一下如何重启es也是没有答案,我硬着头皮,算是琢磨出来了,借此写博,希望能帮助您。
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。

2.杀掉进程 kill -9 2382(进程号)
//杀掉杀掉统统杀掉,如果不确定进程号,可以看看上面信息里面的进程路径地址,防止杀错
[root@bjdhj-125-203 _site]# kill -9 2382
[root@bjdhj-125-203 _site]# ps -ef | grep elastic
