Javaのインストール

Elasticsearchの実行にはJava 7以降が必須
Java 8 update 20以降またはJava 7 update 77以降を推奨

CentOSのリポジトリでJava(OpenJDK)を探す。

$ yum search openjdk

Java 8のランタイムをインストールする。

$ sudo yum install java-1.8.0-openjdk -y
$ java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

Elasticreserchのインストール

$ wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/rpm/elasticsearch/2.3.2/elasticsearch-2.3.2.rpm
$ sudo rpm -ivh elasticsearch-2.3.2.rpm
$ sudo systemctl daemon-reload
$ sudo systemctl enable elasticsearch.service

Elasticsearchの設定

ローカルホストに加えて、VagrantのホストOS側からのアクセスも許す

/etc/elasticsearch/elasticsearch.yml

network.host: [127.0.0.1, 192.168.33.10]

Elasticsearchの実行

$ sudo service elasticsearch start

ざっくり動作確認

まずはローカルホストのシェルから

$ curl -X GET 'http://localhost:9200'
{
  "name" : "Possessor",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "2.3.2",
    "build_hash" : "b9e4a6acad4008027e4038f6abed7f7dba346f94",
    "build_timestamp" : "2016-04-21T16:03:47Z",
    "build_snapshot" : false,
    "lucene_version" : "5.5.0"
  },
  "tagline" : "You Know, for Search"
}

次にホストOSのブラウザから

http://192.168.33.10:9200/
{
  "name" : "Georgianna Castleberry",
  "cluster_name" : "elasticsearch",
  "version" : {
  "number" : "2.3.2",
  "build_hash" : "b9e4a6acad4008027e4038f6abed7f7dba346f94",
  "build_timestamp" : "2016-04-21T16:03:47Z",
  "build_snapshot" : false,
  "lucene_version" : "5.5.0"
  },
  "tagline" : "You Know, for Search"
}

Headプラグインのインストール

$ cd /usr/share/elasticsearch
$ sudo bin/plugin install mobz/elasticsearch-head
$ sudo service elasticsearch restart
