正如这里所写的那样，Elasticsearch参考[1.5]» 配置» 仓库

建立环境

$ cat /etc/redhat-release ; uname -a
CentOS release 6.6 (Final)
Linux moon 2.6.32-504.16.2.el6.x86_64 #1 SMP Wed Apr 22 06:48:29 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

安装Java

    OracleのJDKをインストールする

Java SE 开发工具包7的下载
从上述地址下载最新版本
截至2015/06/04，[Java SE 开发工具包7u79]是最新版本

# sudo rpm -ihv jdk-7u79-linux-x64.rpm

$ java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

CentOS系统（通过yum）

    レポジトリの取得(ver 1.5)
[elasticsearch-1.5]
name=Elasticsearch repository for 1.5.x packages
baseurl=http://packages.elastic.co/elasticsearch/1.5/centos
gpgcheck=1
gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
enabled=1
    インストール
$ sudo yum install elasticsearch
    起動
$ sudo service elasticsearch start
    起動確認
curl -X GET http://localhost:9200/

$ curl -X GET http://localhost:9200/
{
  "status" : 200,
  "name" : "Right-Winger",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "1.5.2",
    "build_hash" : "62ff9868b4c8a0c45860bebb259e21980778ab1c",
    "build_timestamp" : "2015-04-27T09:21:06Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  },
  "tagline" : "You Know, for Search"
}
    上記正常に起動出来る事が分かったのでサーバ起動時に自動起動設定
$ sudo chkconfig elasticsearch on
$ sudo chkconfig elasticsearch --list

确认动作

    データを登録
# curl -XPUT http://localhost:9200/mytest/test/1 -d '{ "title":"memo", "text":"ほげほげ" }'

{"_index":"mytest","_type":"test","_id":"1","_version":1,"created":true}
    データの確認
$ curl -XGET http://localhost:9200/mytest/test/_search -d '{ "query": { "match": { "title":"memo" } } }'

{"took":2,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":0,"max_score":null,"hits":[]}}
    データの削除
$ curl -XDELETE http://localhost:9200/mytest/test/1


{"found":false,"_index":"mytest","_type":"test","_id":"1","_version":1}

安装适用于Elasticsearch的日语支持插件(kuromoji)。

    elastic/elasticsearch-analysis-kuromoji

截至2015年6月4日，es1.5x系列已支持elasticsearch-analysis-kuromoji/2.5.0。

$ sudo bin/plugin install elasticsearch/elasticsearch-analysis-kuromoji/2.5.0
    設定の反映のために、esの再起動
$ sudo service elasticsearch restart

通过kuromoji-analyzer进行动作确认。

    データの投入
$ curl -XPUT http://localhost:9200/kuromoji_sample -d '{ "index": { "analysis": { "tokenizer": { "kuromoji_user_dict" : { "type":"kuromoji_tokenizer" } }, "analyzer": { "analyzer": { "type":"custom", "tokenizer": "kuromoji_user_dict" } } } } }'

{"acknowledged":true}
    この新しく作成したインデックスに対して日本語文字列を POST して、形態素解析が有効になっているかどうかを確認
$ curl -XPOST 'http://localhost:9200/kuromoji_sample/_analyze?analyzer=analyzer&pretty' -d '月島もんじゃ'
{
  "tokens" : [ {
    "token" : "月島",
    "start_offset" : 0,
    "end_offset" : 2,
    "type" : "word",
    "position" : 1
  }, {
    "token" : "もんじゃ",
    "start_offset" : 2,
    "end_offset" : 6,
    "type" : "word",
    "position" : 2
  } ]
}
    kuromoji を使ったインデックスを ElasticSearch のデフォルトアナライザとして指定し、ElasticSearch を再起動します
$ sudo echo "index.analysis.analyzer.default.type: custom"                  >> /etc/elasticsearch/elasticsearch.yml
$ sudo echo "index.analysis.analyzer.default.tokenizer: kuromoji_user_dict" >> /etc/elasticsearch/elasticsearch.yml
$ sudo service elasticsearch restart
    改めて、データの投入
$ curl -XPUT http://localhost:9200/kuromoji_sample/test/1 -d '{ "title":"メモ １", "text":"今夜の夕食が楽しみ" }'
$ curl -XPUT http://localhost:9200/kuromoji_sample/test/1 -d '{ "title":"メモ １", "text":"来週の刃牙が楽しみ" }'
{"_index":"kuromoji_sample","_type":"test","_id":"1","_version":2,"created":false}
    データの検索
$ curl -XGET http://localhost:9200/kuromoji_sample/test/_search -d '{"query":{"match":{"text":"刃牙"}}}'

{"took":12,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":1,"max_score":0.16273327,"hits":[{"_index":"kuromoji_sample","_type":"test","_id":"1","_score":0.16273327,"_source":{ "title":"メモ１", "text":"来週の刃牙が楽しみ" }}]}}
