用途

前情提要：

▷ 在第一篇《EFK教程 - 快速入门指南》中，阐述了EFK的安装部署，其中ES的架构为三节点，即master、ingest、data角色同时部署在三台服务器上。 ▷ 在第二篇《EFK教程 - ElasticSearch高性能高可用架构》中，阐述了EFK的data/ingest/master角色的用途及分别部署三节点，在实现性能最大化的同时保障高可用

前两篇文章，ES集群中只存在一个实例，而在本文中，将在一个集群中部署多个ES实例，来实现资源合理分配。例如data服务器存在SSD与SAS硬盘，可以将热数据存放到SSD，而冷数据存放到SAS，实现数据冷热分离。

在本文中，将为data服务器创建2个实例，分别基于SSD和基于SAS硬盘，将nginx的9月份索引放在SAS盘上，其它的全放在SSD盘上

192.168.1.51 elasticsearch-data部署双实例

索引迁移（此步不能忽略）：将192.168.1.51上的索引放到其它2台data节点上

  1. curl -X PUT "192.168.1.31:9200/*/_settings?pretty" -H 'Content-Type: application/json' -d'

  2. {

  3. "index.routing.allocation.include._ip": "192.168.1.52,192.168.1.53"

  4. }'

确认当前索引存储位置：确认所有索引不在192.168.1.51节点上

  1. curl "http://192.168.1.31:9200/_cat/shards?h=n"

 

 

停掉192.168.1.51的进程，修改目录结构及配置：请自行按SSD和SAS硬盘挂载好数据盘
