首先来看官网给的版本要求：
红框这栏指的是：Elasticsearch安装版本（windows安装版本或Linux按照版本）
最新因为项目需要elasticsearch，采用今天搞了好久，项目启动就报如下错误：
org.elasticsearch.transport.NodeDisconnectedException: [][127.0.0.1:9300][cluster:monitor/nodes/liveness] disconnected
找了好久以为是配置问题，最后终于明白原来是版本不统一。
我的项目用的spring boot 1.5.x
所以安装了elasticsearch-2.3.2.zip
解压进入bin目录双击elasticsearch.bat。启动服务。
在浏览器输入http://localhost:9200/，返回json字符串证明启动成功。

在springboot中对elasticsearch配置是默认有支持的。
如配置：
| #默认 9300 是 Java 客户端的端口。9200 是支持 Restful HTTP 的接口。 # 集群节点地址列表，用逗号分隔。如果没有指定，就启动一个客户端节点 spring.data.elasticsearch.cluster-nodes=127.0.0.1:9300 spring.data.elasticsearch.cluster-name=elasticsearch spring.data.elasticsearch.repositories.enabled=true |
以前就绪，操作就类似于Spring-Data-JPA,具体见官方文档http://projects.spring.io/spring-data-elasticsearch/
