基于ElasticSearch多實例架構，實現(xiàn)資源合理分配、冷熱數(shù)據(jù)分離

用途

前情提要：

? 在第一篇《EFK教程 - 快速入門指南》中，闡述了EFK的安裝部署，其中ES的架構為三節(jié)點，即master、ingest、data角色同時部署在三臺服務器上。
? 在第二篇《EFK教程 - ElasticSearch高性能高可用架構》中，闡述了EFK的data/ingest/master角色的用途及分別部署三節(jié)點，在實現(xiàn)性能最大化的同時保障高可用

前兩篇文章，ES集群中只存在一個實例，而在本文中，將在一個集群中部署多個ES實例，來實現(xiàn)資源合理分配。例如data服務器存在SSD與SAS硬盤，可以將熱數(shù)據(jù)存放到SSD，而冷數(shù)據(jù)存放到SAS，實現(xiàn)數(shù)據(jù)冷熱分離。

在本文中，將為data服務器創(chuàng)建2個實例，分別基于SSD和基于SAS硬盤，將nginx的9月份索引放在SAS盤上，其它的全放在SSD盤上

EFK教程(3) - ElasticSearch多實例部署

192.168.1.51 elasticsearch-data部署雙實例

索引遷移（此步不能忽略）：將192.168.1.51上的索引放到其它2臺data節(jié)點上

curl -X PUT "192.168.1.31:9200/*/_settings?pretty" -H 'Content-Type: application/json' -d'
{
  "index.routing.allocation.include._ip": "192.168.1.52,192.168.1.53"
}'

確認當前索引存儲位置：確認所有索引不在192.168.1.51節(jié)點上

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

EFK教程(3) - ElasticSearch多實例部署

停掉192.168.1.51的進程，修改目錄結構及配置：請自行按SSD和SAS硬盤掛載好數(shù)據(jù)盤
