首先來看官網給的版本要求：
紅框這欄指的是：Elasticsearch安裝版本（windows安裝版本或Linux按照版本）
最新因為項目需要elasticsearch，采用今天搞了好久，項目啟動就報如下錯誤：
org.elasticsearch.transport.NodeDisconnectedException: [][127.0.0.1:9300][cluster:monitor/nodes/liveness] disconnected
找了好久以為是配置問題，最后終於明白原來是版本不統一。
我的項目用的spring boot 1.5.x
所以安裝了elasticsearch-2.3.2.zip
解壓進入bin目錄雙擊elasticsearch.bat。啟動服務。
在瀏覽器輸入http://localhost:9200/，返回json字符串證明啟動成功。

在springboot中對elasticsearch配置是默認有支持的。
如配置：
| #默認 9300 是 Java 客戶端的端口。9200 是支持 Restful HTTP 的接口。 # 集群節點地址列表，用逗號分隔。如果沒有指定，就啟動一個客戶端節點 spring.data.elasticsearch.cluster-nodes=127.0.0.1:9300 spring.data.elasticsearch.cluster-name=elasticsearch spring.data.elasticsearch.repositories.enabled=true |
以前就緒，操作就類似於Spring-Data-JPA,具體見官方文檔http://projects.spring.io/spring-data-elasticsearch/
