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
a)cluster.name: ns-cluster(同一集群要一样)
b)node.name： node-1
c)network.Host: 192.168.1.101
d)防止脑裂的配置
discovery.zen.ping.multicast.enabled: false

client.transport.ping_timeout: 60s
discovery.zen.ping.unicast.hosts: ["192.168.1.100","192.168.1.101", "192.168.1.102"]
NIE-01: 192.168.1.102
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：

0. 前提是：hosts
192.168.1.100NIE-00
192.168.1.101 NIE-01
192.168.1.102 NIE-02
{

"build_snapshot" : false,

},
"tagline" : "You Know, for Search"

最简安装还是蛮easy的。
