es数据的冷热分离实验

系统版本:CentOS7

节点规划:

热数据节点:  192.168.2.4

温数据节点:  192.168.2.190

PS:这里就没分 hot warm cold 这种三级存储,我们一般使用 hot warm 2种即可。

热数据节点:  192.168.2.4 的配置如下:

cluster.name: my-application

node.name: node-1
node.attr.rack: r1

node.attr.temperature: hot

path.data: ./data/
path.logs: ./logs

node.master: true
node.data: true
node.ingest: true

bootstrap.memory_lock: true

network.host: 0.0.0.0
http.port: 9200

cluster.initial_master_nodes: 
  - 192.168.2.4:9300
  - 192.168.2.190:9300
  
discovery.seed_hosts:
  - 192.168.2.4
  - 192.168.2.190
  
gateway.recover_after_nodes: 1
#action.destructive_requires_name: true
############# xpack 的配置项 ####################
#xpack.security.enabled: true
#xpack.security.transport.ssl.enabled: true
xpack.security.audit.enabled: true
xpack.security.audit.logfile.events.include: access_denied, access_granted, anonymous_access_denied, authentication_failed,connection_denied, tampered_request, run_as_denied, run_as_granted
xpack.security.audit.logfile.emit_node_host_address: true
xpack.security.audit.logfile.emit_node_host_name: true
xpack.sql.enabled: true
xpack.ilm.enabled: true

温数据节点:  192.168.2.190

cluster.name: my-application

node.name: es11
node.attr.rack: r1

node.attr.temperature: warm

path.data: ./data/
path.logs: ./logs

node.master: true
node.data: true
node.ingest: true

bootstrap.memory_lock: true

network.host: 0.0.0.0
http.port: 9200

cluster.initial_master_nodes: 
  - 192.168.2.4:9300
  - 192.168.2.190:9300
  
discovery.seed_hosts:
  - 192.168.2.4
  - 192.168.2.190
gateway.recover_after_nodes: 1

#action.destructive_requires_name: true

############# xpack 的配置项 ####################
#xpack.security.enabled: true
#xpack.security.transport.ssl.enabled: true
xpack.security.audit.enabled: true
xpack.security.audit.logfile.events.include: access_denied, access_granted, anonymous_access_denied, authentication_failed,connection_denied, tampered_request, run_as_denied, run_as_granted
xpack.security.audit.logfile.emit_node_host_address: true
xpack.security.audit.logfile.emit_node_host_name: true
xpack.sql.enabled: true
xpack.ilm.enabled: true

创建索引,并将数据搬迁到hot节点:

curl -H 'Content-Type: application/json' -X PUT http://localhost:9200/index-2019.10.19?pretty
curl -H 'Content-Type: application/json' -X PUT http://localhost:9200/index-2019.10.19/_settings -d '
{
  "index.routing.allocation.require.temperature": "hot"
}'

如果要将 index-2019.10.19 的数据搬迁到温节点,我们使用下面的这个命令就行

curl -H 'Content-Type: application/json' -X PUT http://localhost:9200/index-2019.10.19/_settings -d '
{
  "index.routing.allocation.require.temperature": "warm"
}'

流程跑通后,我们可以写个脚本,将7天前的索引,打标签,存放到es的warm节点(大容量HDD磁盘):

#!/bin/bash

day=$(date +"%Y.%m.%d" -d -7day)
# echo ${day}

curl -H 'Content-Type: application/json'  -X PUT http://192.168.2.4:9200/*-${day}/_settings -d '
{
  "index.routing.allocation.require.temperature": "warm"
}'

另外, 在es7里面 提供 index-lifecycle-management 这个功能, 我们在kibana 界面里面就可以进行配置。 具体可以查阅es官方的文档
