集羣安裝：
三個節點：master,slave1,slvae2
vi elasticsearch.yml
cluster.name: my-application
node.name: node-3(節點獨有的名稱，注意唯一性)
network.host: 192.168.137.117
http.port: 9200
discovery.zen.ping.unicast.hosts: ["master","slave1", "slave2"]
安裝插件
/home/qun/soft/elasticsearch-2.3.3/bin/plugin install analysis-icu
/home/qun/soft/elasticsearch-2.3.3/bin/plugin install mobz/elasticsearch-head
marvel：
/home/qun/soft/elasticsearch-2.3.3/bin/plugin install license
/home/qun/soft/elasticsearch-2.3.3/bin/plugin install marvel-agent
在各個節點上執行：
elasticsearch -d
殺死節點
kill -9 `ps -ef|grep elasticsearch|awk '{print $2}'`
啓動
/home/qun/soft/elasticsearch-2.3.3/bin/elasticsearch -d
訪問集羣：
http://master:9200/_plugin/head/
一個節點(node)就是一個Elasticsearch實例，而一個集羣(cluster)由一個或多個節點組成，它們具有相同的cluster.name，
它們協同工作，分享數據和負載。當加入新的節點或者刪除一個節點時，集羣就會感知到並平衡數據。
做爲用戶，我們能夠與集羣中的任何節點通信，包括主節點。每一個節點都知道文檔存在於哪個節點上，它們可以轉發請求到相應的節點上。
我們訪問的節點負責收集各節點返回的數據，最後一起返回給客戶端。這一切都由Elasticsearch處理。

添加用戶自定義詞典：

栗子:添加sougou.dic,分號分隔，相對路徑，重啓es集羣

配置同義詞
修改：elasticsearch-2.3.3/config/elasticsearch.yml,在末尾加上如下內容
index: analysis: analyzer: ik_syno: type: custom tokenizer: ik_max_word filter: [my_synonym_filter] ik_syno_smart: type: custom tokenizer: ik_smart filter: [my_synonym_filter] filter: my_synonym_filter: type: synonym synonyms_path: analysis/synonym.txt
添加詞典：
mkdir -p elasticsearch-2.3.3/config/analysis
vi elasticsearch-2.3.3/config/analysis/synonym.txt
ipod, i-pod, i pod
foozball , foosball
universe , cosmos
西紅柿, 番茄
