1. 解压elasticsearch.2.4.2；3个节点
2. 修改config/elasticsearch.yml
(注意要顶格写，冒号后面要加一个空格)
NIE-00: 192.168.1.100
a)cluster.name: ns-cluster (同一集群要一样) b)node.name： node-0 c)network.Host: 192.168.1.100 d)防止脑裂的配置 discovery.zen.ping.multicast.enabled: false discovery.zen.ping_timeout: 120s client.transport.ping_timeout: 60s discovery.zen.ping.unicast.hosts:["192.168.1.100","192.168.1.101","192.168.1.102"]
NIE-01: 192.168.1.101

NIE-01: 192.168.1.102
a)cluster.name: ns-cluster (同一集群要一样) b)node.name： node-2 c)network.Host: 192.168.1.102 d)防止脑裂的配置 discovery.zen.ping.multicast.enabled: false discovery.zen.ping_timeout: 120s client.transport.ping_timeout: 60s discovery.zen.ping.unicast.hosts: ["192.168.1.100","192.168.1.101", "192.168.1.102"]
3. 启动：nohup ./bin/elasticsearch >es.log 2>&1 &
控制台输出如下：

其他两个节点，同上，启动；
4. 浏览器访问：
http://nie-02:9200/
http://nie-02:9200/?pretty
0. 前提是：hosts
192.168.1.100 NIE-00 192.168.1.101 NIE-01 192.168.1.102 NIE-02 { "name" : "node-2", "cluster_name" : "ns-cluster", "cluster_uuid" : "na", "version" : { "number" : "2.4.2", "build_hash" : "161c65a337d4b422ac0c805f284565cf2014bb84", "build_timestamp" : "2016-11-17T11:51:03Z", "build_snapshot" : false, "lucene_version" : "5.5.2" }, "tagline" : "You Know, for Search" }
最简安装还是蛮easy的。
今天先到这里。
