Mac で Elasticsearch 6

Last updated at Posted at 2017-12-13

事情があってelasticsearchの導入をしようとしているのですが、何も考えずに導入したv6は出たばかりのバージョンらしく、解説がどこにもない。。。

苦労して導入中のメモを残しておきます。

java8の導入

(JDKがないと言われたので、javaを導入したらjava9でダメ)

$ brew cask install java8

elasticsearch 導入 & 自動起動の設定

$ brew install elasticsearch
$ ln -sfv /usr/local/opt/elasticsearch/*.plist ~/Library/LaunchAgents
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.elasticsearch.plist

URL: http://localhost:9200

うまくいくと、下のような結果がブラウザに返ってきます。

{
  "name" : "5egFqAz",
  "cluster_name" : "elasticsearch_makaishi",
  "cluster_uuid" : "Yw_85VZrRwigNvlIl0rD4g",
  "version" : {
    "number" : "6.0.1",
    "build_hash" : "601be4a",
    "build_date" : "2017-12-04T09:29:09.525Z",
    "build_snapshot" : false,
    "lucene_version" : "7.0.1",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

プラグインの導入

$ cd /usr/local/Cellar/elasticsearch/6.0.1
$ bin/elasticsearch-plugin install analysis-icu
$ bin/elasticsearch-plugin install analysis-kuromoji

###index作成

$ curl -X PUT http://localhost:9200/test

###index設定確認

$ curl -X GET localhost:9200/test/_stats?pretty=true

###データ投入
content-typeを指定する必要あり

$ curl -H "Content-Type: application/json" -XPOST localhost:9200/index/type -d '{"message": "test message"}'

kibanaの導入・起動

$ brew install kibana
$ kibana

url: http://localhost:5601/

うまくいくとこういう画面が出てきます。

        }
