注意:演示用的2節點es,有些參數配置不太合理,生產環境還須要更嚴格的參數設定(例如必須開啓密碼驗證)。node
系統版本:CentOS7sql
節點規劃:json
熱數據節點: 192.168.2.4bootstrap
溫數據節點: 192.168.2.190bash
PS:這裏就沒分 hot warm cold 這種三級存儲,咱們通常使用 hot warm 2種便可。app
咱們這裏使用 tar.gz 通用二進制文件curl
useradd eselasticsearch
# cat /etc/security/limits.d/elasticsearch.conf ide
es - nofile 65535 es - noproc 65535 es - memlock unlimited
cd /usr/local/elasticsearch-7.4.2/ui
mkdir data logs
chown es.es /usr/local/elasticsearch-7.4.2/ -R
su - es
cd /usr/local/elasticsearch-7.4.2/
熱數據節點: 192.168.2.4 的配置以下:
cat config/elasticsearch.yml
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 的配置項 #################### #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
溫數據節點: 192.168.2.190
cat config/elasticsearch.yml

啓動腳本:
# cat start.sh
# es 依賴高版本的jdk 須要先export下 export JAVA_HOME=./jdk/ nohup ./bin/elasticsearch >/dev/null 2>&1 &
中止腳本:
# cat stop.sh
kill $(jps| grep Elasticsearch | awk '{print $1}')
建立索引,並將數據搬遷到hot節點:
curl -H 'Content-Type: application/json' -X PUT http://localhost:9200/index-2019.10.19?pretty curl -H 'Content-Type: application/json' -X PUT http://localhost:9200/index-2019.10.19/_settings -d ' { "index.routing.allocation.require.temperature": "hot" }'
若是要將 index-2019.10.19 的數據搬遷到溫節點,咱們使用下面的這個命令就行
curl -H 'Content-Type: application/json' -X PUT http://localhost:9200/index-2019.10.19/_settings -d ' { "index.routing.allocation.require.temperature": "warm" }'
流程跑通後,咱們能夠寫個腳本,做用有2個:
一、提早建立後一天的索引,並確保將其落到hot節點
二、將7天前的索引,打標籤,存放到es的warm節點(大容量HDD磁盤):
#!/bin/bash # 建立新的索引,語句相似下面5行,須要根據本身狀況修改(建議使用for循環建立index) # curl -H 'Content-Type: application/json' -X PUT http://localhost:9200/index-2019.10.19?pretty # curl -H 'Content-Type: application/json' -X PUT http://localhost:9200/index-2019.10.19/_settings -d ' # { # "index.routing.allocation.require.temperature": "hot" # }' day=$(date +"%Y.%m.%d" -d -7day) 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裏面 提供 index-lifecycle-management 這個功能, 咱們在kibana 界面裏面就能夠進行配置。 具體能夠查閱es官方的文檔(我的仍是比較喜歡用上面的這種腳本的方案)。
