[setting] elasticsearch 環境構築メモ

Last updated at Posted at 2024-11-28

環境構築メモ

二つの場合のインストール手順をメモります。brewでインストールだとelastic search 8系がインストールされませんでした。近似近傍探索には8系が良いとのことで8系を二つ目の手順でインストールしてます。

brewを使用してinstall

macOS

% brew install elastic/tap/elasticsearch-full

logは次のようになる。[user name]はwhoamiの値です。

Data:    /opt/homebrew/var/lib/elasticsearch/elasticsearch_[user name]/
Logs:    /opt/homebrew/var/log/elasticsearch/elasticsearch_[user name].log
Plugins: /opt/homebrew/var/elasticsearch/plugins/
Config:  /opt/homebrew/etc/elasticsearch/

% elasticsearch --version
Version: 7.17.4, Build: default/tar/79878662c54c886ae89206c685d9f1051a9d6411/2022-05-18T18:04:20.964345128Z, JVM: 18.0.1.1

defaultのまま使用する場合は下記不要

home直下にフォルダを作成してその中にファイルをコピー

% cp /opt/homebrew/etc/elasticsearch/elasticsearch.yml .
% cp /opt/homebrew/etc/elasticsearch/jvm.options .
% cp /opt/homebrew/etc/elasticsearch/log4j2.properties .

Elasticsearch起動

% elasticsearch

% curl http://localhost:9200/

}

foo_indexを付与

実験のため、同じドキュメントをもう一つ追加。

% curl --include -XPOST "http://localhost:9200/foo_index/_doc?pretty" \
-H 'Content-Type: application/json' \
-d '{

foo_indexを指定して値を取得

% curl --include -XGET "http://localhost:9200/foo_index/_doc/7VqccJMBqNjbFLONavLW?pretty"

{

  "_version" : 1,
  "_seq_no" : 2,
  "_primary_term" : 1,
  "found" : true,
  "_source" : {
    "foo_user" : "ボブ",
    "foo_message" : "夜は若く、彼も若かった。が、夜の空気は甘いのに、彼の気分は苦かった。"
  }
}

検索条件"foo_message": "夜の空気"として、条件に一致する値を取得。

% curl --include -XGET "http://localhost:9200/foo_index/_search?pretty" \
-H 'Content-Type: application/json' \
-d '
{
  "query": {
    "match": {
      "foo_message": "夜の空気"
    }
  }
}'

追加された二つの値が取得されていることを確認する。

version指定でダウンロードする方法

homeで下記を実行。今回はelasticsearch-8.16.1をダウンロードします。

curl -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.16.1-darwin-x86_64.tar.gz
curl https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.16.1-darwin-x86_64.tar.gz.sha512 | shasum -a 512 -c - 
tar -xzf elasticsearch-8.16.1-darwin-x86_64.tar.gz

！！重要！！

バイナリを実行する前に、

mac userはGatekeeperが「開発元が不明のため実行できません」的なエラーを出力するため、実行できないです。なので、ダウンロードしたフォルダに対して、以下を実行して許可します。

% xattr -d -r com.apple.quarantine elasticsearch-8.16.1

実行確認

cd elasticsearch-8.16.1
./bin/elasticsearch --version
Version: 8.16.1, Build: tar/ffe992aa682c1968b5df375b5095b3a21f122bf3/2024-11-19T16:00:31.793213192Z, JVM: 23

成功です。

PATHを通す

.zshrcファイルでバイナリに対してパスを通します。brew installしたものよりも先にヒットしてほしいので、左にパスを追加します。（brew installしたものはuninstallしてしまいましょ）

sudo vi ~/.zshrc
export ELASTICSEARCH="/Users/[user name]/elasticsearch-8.16.1/bin"
export PATH="$ELASTICSEARCH:$PATH"

パスが追加されているか確認します。

echo $PATH

適用

source ~/.zshrc

version確認

% elasticsearch --version
Version: 8.16.1, Build: tar/ffe992aa682c1968b5df375b5095b3a21f122bf3/2024-11-19T16:00:31.793213192Z, JVM: 23

成功です。

追記 brewの方を削除

探索して見つけた順に表示されます。

% where elasticsearch 
/Users/[user name]/elasticsearch-8.16.1/bin/elasticsearch
/opt/homebrew/bin/elasticsearch

brewの方を削除します

% brew uninstall elasticsearch-full

% where elasticsearch    
/Users/mariko/elasticsearch-8.16.1/bin/elasticsearch
