1、JDK安装
对于Elasticsearch来说，至少需要JDK1.7上的版本，但我们建议使用Oracle JDK version 1.8.0_73，JDK的安装这里不再细讲，安装完成之后检查一下JDK的版本
java -version echo $JAVA_HOME
2、下载最新的Elasticsearch版本
curl -L -O https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.3/elasticsearch-2.3.3.tar.gz
扩展知识
curl参数说明
-O/--remote-name 把输出写到该文件中，保留远程文件的文件名
3、解压Elasticsearch
tar -zxvf elasticsearch-2.3.3.tar.gz
3、启动Elasticsearch
cd elasticsearch-2.3.3/bin
前台启动
./elasticsearch
后台启动
./elasticsearch -d
[oracle@sigmam1 bin]$ ./elasticsearch

Elasticsearch可以手动修改节点和集群的名字，也可以在命令行启动时指定，直接修改：
./elasticsearch --cluster.name my_cluster_name --node.name my_node_name
默认情况下，Elasticsearch对外提供的端口是9200，如果要修改默认端口可以修改config目录下的
Elasticsearch.yml配置文件
