Elasticsearch叢集啟動關閉重啟操作
ES叢集如果節點較多，在重啟，關閉，啟動等操作的時候，需要一個一個操作，非常麻煩，下面提供一種方式，可以通過指令碼的方式，在一臺節點上操作即可：
一、配置節點之間免密碼登入；
具體配置方法，請百度搜索下就有了。
二、建立一下指令碼完成操作:
- 叢集啟動
在elasticsearch安裝目錄下建立elasticstart.sh檔案，內容如下：
!/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
程式碼說明：
ssh 100.100.37.26表示ssh方式登陸到伺服器，/home/elasticsearch/bin/service/elasticsearch start 表示啟動ES節點服務。叢集裡面有幾個節點，需要都在此指令碼中添上。
建立完指令碼後，切換到檔案目錄，執行elasticstart.sh 啟動所有節點。
- 叢集重啟
重啟操作與啟動操作步驟一致，重啟檔案內容如下：
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
- 叢集關閉
關閉操作與啟動操作步驟一致，檔案內容如下：
!/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
