elasticsearch2.4.2安装(1)

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

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: 192.168.1.102

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

# 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。
