ElasticSearch关闭重启命令

Posted 2022-10-11 张志翔 ̮

        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。

一. 如何关闭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。

root      8682  8564  0 18:04 pts/0    00:00:00 grep elastic

        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
root      2583     1  0 Jan05 ?        00:10:24 /opt/soft/jdk/jdk1.7.0_80/bin/java -Xms2g -Xmx2g -Djava.awt.headless=true -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -XX:+DisableExplicitGC -Dfile.encoding=UTF-8 -Delasticsearch -Des.path.home=/opt/soft/elasticsearch-1.5.2 -cp :/opt/soft/elasticsearch-1.5.2/lib/elasticsearch-1.5.2.jar:/opt/soft/elasticsearch-1.5.2/lib/*:/opt/soft/elasticsearch-1.5.2/lib/sigar/* org.elasticsearch.bootstrap.Elasticsearch
root      8684  8564  0 18:05 pts/0    00:00:00 grep elastic

        3.重启命令 sh elasticsearch -d

[root@bjdhj-125-203 elasticsearch-1.5.2]# ls
bin  config  data  lib  LICENSE.txt  logs  NOTICE.txt  plugins  README.textile
[root@bjdhj-125-203 elasticsearch-1.5.2]# cd bin
[root@bjdhj-125-203 bin]# ./elasticsearch -d
-bash: ./elasticsearch: Permission denied
 
[root@bjdhj-125-203 bin]# sh elasticsearch -d
