Elasticsearch集群启动关闭重启操作

ES集群如果节点较多，在重启，关闭，启动等操作的时候，需要一个一个操作，非常麻烦，下面提供一种方式，可以通过脚本的方式，在一台节点上操作即可：

一、配置节点之间免密码登录；

具体配置方法，请百度搜索下就有了。

二、创建一下脚本完成操作:

1. 集群启动
   在elasticsearch安装目录下创建elasticstart.sh文件，内容如下：

!/bin/bash

ssh 100.100.37.26 /home/elasticsearch/bin/service/elasticsearch start
ssh 100.100.37.27 /home/elasticsearch/bin/service/elasticsearch start
ssh 100.100.37.28 /home/elasticsearch/bin/service/elasticsearch start
ssh 100.100.37.29 /home/elasticsearch/bin/service/elasticsearch start
ssh 100.100.37.30 /home/elasticsearch/bin/service/elasticsearch start
ssh 100.100.37.31 /home/elasticsearch/bin/service/elasticsearch start
ssh 100.100.37.32 /home/elasticsearch/bin/service/elasticsearch start
ssh 100.100.37.33 /home/elasticsearch/bin/service/elasticsearch start

代码说明：
ssh 100.100.37.26表示ssh方式登陆到服务器，/home/elasticsearch/bin/service/elasticsearch start 表示启动ES节点服务。集群里面有几个节点，需要都在此脚本中添上。

创建完脚本后，切换到文件目录，执行elasticstart.sh 启动所有节点。

1. 集群重启
   重启操作与启动操作步骤一致，重启文件内容如下：

ssh 100.100.37.26 /home/elasticsearch/bin/service/elasticsearch restart
ssh 100.100.37.27 /home/elasticsearch/bin/service/elasticsearch restart
ssh 100.100.37.28 /home/elasticsearch/bin/service/elasticsearch restart
ssh 100.100.37.29 /home/elasticsearch/bin/service/elasticsearch restart
ssh 100.100.37.30 /home/elasticsearch/bin/service/elasticsearch restart
ssh 100.100.37.31 /home/elasticsearch/bin/service/elasticsearch restart
ssh 100.100.37.32 /home/elasticsearch/bin/service/elasticsearch restart
ssh 100.100.37.33 /home/elasticsearch/bin/service/elasticsearch restart

1. 集群关闭
   关闭操作与启动操作步骤一致，文件内容如下：

!/bin/bash

ssh 100.100.37.26 /home/elasticsearch/bin/service/elasticsearch stop
ssh 100.100.37.27 /home/elasticsearch/bin/service/elasticsearch stop
ssh 100.100.37.28 /home/elasticsearch/bin/service/elasticsearch stop
ssh 100.100.37.29 /home/elasticsearch/bin/service/elasticsearch stop
ssh 100.100.37.30 /home/elasticsearch/bin/service/elasticsearch stop
ssh 100.100.37.31 /home/elasticsearch/bin/service/elasticsearch stop
ssh 100.100.37.32 /home/elasticsearch/bin/service/elasticsearch stop
ssh 100.100.37.33 /home/elasticsearch/bin/service/elasticsearch stop
