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的架構為三節點,即master、ingest、data角色同時部署在三臺伺服器上。 ▷ 在第二篇《EFK教程 - ElasticSearch高效能高可用架構》中,闡述了EFK的data/ingest/master角色的用途及分別部署三節點,在實現效能最大化的同時保障高可用
前兩篇文章,ES叢集中只存在一個例項,而在本文中,將在一個叢集中部署多個ES例項,來實現資源合理分配。例如data伺服器存在SSD與SAS硬碟,可以將熱資料存放到SSD,而冷資料存放到SAS,實現資料冷熱分離。
在本文中,將為data伺服器建立2個例項,分別基於SSD和基於SAS硬碟,將nginx的9月份索引放在SAS盤上,其它的全放在SSD盤上

192.168.1.51 elasticsearch-data部署雙例項
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"
-
}'
確認當前索引儲存位置:確認所有索引不在192.168.1.51節點上
-
curl "http://192.168.1.31:9200/_cat/shards?h=n"
停掉192.168.1.51的程序,修改目錄結構及配置:請自行按SSD和SAS硬碟掛載好資料盤
