指定节点类型 方式

方式一 启动加入 节点类型 参数

./bin/elasticsearch -Enode.attr.box_type=hot

方式二 配置文件 修改 elasticsearch.yml

node.attr.box_type: "type" # type为该node类型  自定义

通过Kibana 配置index属性

1、设置已有的index 到指定node上

PUT /test-index/_settings 
{ 
 "settings": { 
   "index.routing.allocation.require.box_type": "hot",
   "index.number_of_replicas": "0"
 } 
}

2、在模板指定类型

PUT _template/active-logs 
{ 
  "template": "active-logs-*", 
  "settings": { 
    "number_of_shards":   5, 
    "number_of_replicas": 1, 
    "routing.allocation.include.box_type": "hot", 
    "routing.allocation.total_shards_per_node": 2 
  }, 
  "aliases": { 
    "active-logs":  {} 
  } 
}

指定索引模板只把新数据放到hot节点上面

PUT /_template/hot_template
{
  "template": "*",
  "order": 0,
  "version": 0,
  "settings": {
    "index": {
      "routing": {
        "allocation": {
          "require": {
            "box_type": "hot"
          },
          "exclude":{
            "box_type": "warm"
          }
        }
      },
      "number_of_shards": 3,
      "number_of_replicas": 1,
      "refresh_interval": "50s"
    },
    "index.unassigned.node_left.delayed_timeout": "3d"
  }
}
