[ 2 修改配置檔案 elasticsearch.yml
/home/hadoop/apps/elasticsearch-2.3.1/config
#叢集名稱，通過組播的方式通訊，通過名稱判斷屬於哪個叢集 cluster.name: TzbBigData #節點名稱，要唯一 node.name: node-1 #資料存放位置 path.data: /home/hadoop/elasticsearchData/data #日誌存放位置 path.logs: /home/hadoop/elasticsearchData/logs #es繫結的ip地址 network.host: 192.168.30.131 #初始化時可進行選舉的節點 discovery.zen.ping.unicast.hosts: ["node1", "node2","node3"]
3 拷貝到其他節點
scp -r /home/hadoop/apps/elasticsearch-2.3.1/ node2:/home/hadoop/apps
scp -r /home/hadoop/apps/elasticsearch-2.3.1/ node3:/home/hadoop/apps
修改node2,node3 的配置檔案的 node.name和network.host
4 啟動
es 啟動時要求非 root 使用者
三個節點同時操作
/home/hadoop/apps/elasticsearch-2.3.1/bin/elasticsearch -d
瀏覽器訪問 http://node1:9200/
5 測試
RESTful介面URL的格式：
http://localhost:9200/<index>/<type>/[<id>]
其中index、type是必須提供的。
id是可選的，不提供es會自動生成。
index、type將資訊進行分層，利於管理。
index可以理解為資料庫；type理解為資料表；id相當於資料庫表中記錄的主鍵，是唯一的。
在命令列用 curl ,新增資料
curl -XPUT 'http://node1:9200/store/books/1' -d '{
"title": "Elasticsearch: The Definitive Guide",
"name" : {
"first" : "Zachary",
"last" : "Tong"
},
"publish_date":"2018-10-25",
"price":"49.99"
}'
5.1 獲取資料
瀏覽器訪問 http://node1:9200/store/books/1
curl -XGET 'http://node1:9200/store/books/1'
