1 解压

[hadoop@node1 ~]$ ll total 42708 drwxrwxr-x. 9 hadoop hadoop 180 Oct 24 21:33 apps -rw-r--r--. 1 hadoop hadoop 27540442 Jun 10 2017 elasticsearch-2.3.1.tar.gz drwxrwxr-x. 4 hadoop hadoop 28 Sep 14 19:02 hbase drwxrwxr-x. 4 hadoop hadoop 32 Sep 14 14:44 hdfsdir -rw-r--r--. 1 hadoop hadoop 16162559 Jun 24 12:55 kafka_2.10-0.8.2.1.tgz drwxrwxrwx. 3 hadoop hadoop 18 Oct 24 21:45 kafkaData -rw-rw-r--. 1 hadoop hadoop 0 Oct 24 21:58 log-cleaner.log drwxrwxr-x. 5 hadoop hadoop 133 Oct 23 14:40 metastore_db drwxrwxr-x. 3 hadoop hadoop 63 Oct 24 21:21 zookeeperData -rw-rw-r--. 1 hadoop hadoop 26108 Oct 25 17:54 zookeeper.out [hadoop@node1 ~]$ tar -zxvf elasticsearch-2.3.1.tar.gz -C /home/hadoop/apps/

2 修改配置文件 elasticsearch.yml

/home/hadoop/apps/elasticsearch-2.3.1/config

#集群名称，通过组播的方式通信，通过名称判断属于哪个集群 cluster.name: TzbBigData #节点名称，要唯一 node.name: node-1 #数据存放位置 path.data: /home/hadoop/elasticsearchData/data #日志存放位置 path.logs: /home/hadoop/elasticsearchData/logs #es绑定的ip地址 network.host: 192.168.30.131 #初始化时可进行选举的节点 discovery.zen.ping.unicast.hosts: ["node1", "node2","node3"]

3 拷贝到其他节点

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 的配置文件的 node.name和network.host

4 启动

es 启动时要求非 root 用户 三个节点同时操作

/home/hadoop/apps/elasticsearch-2.3.1/bin/elasticsearch -d

浏览器访问 http://node1:9200/

5 测试

RESTful接口URL的格式： http://localhost:9200/<index>/<type>/[<id>] 其中index、type是必须提供的。 id是可选的，不提供es会自动生成。 index、type将信息进行分层，利于管理。 index可以理解为数据库；type理解为数据表；id相当于数据库表中记录的主键，是唯一的。

在命令行用 curl ,添加数据

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 获取数据

浏览器访问 http://node1:9200/store/books/1

curl -XGET 'http://node1:9200/store/books/1'

6 es 离线安装插件
