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

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"
}'

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

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

EFK教程(3)

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
