Magento2.3.5でElasticsearchを使用する

初めに

サンプルデータを入れるためにあえて古いバージョンを入れたMagentoですが、V2.3.5では検索エンジンがMySqlでした。これをElasticSearchに変更します。

/etc/elasticsearch/elasticsearch.ymlの編集

赤線部分（clust）をnode.nameで定義した My First Node に変更します。

その後、elasticsearchを再起動します。ちなみにelasticsearchのログは/var/log/elasticsearch/の下にあります。

sudo systemctl daemon-reload
sudo systemctl restart elasticsearch.service

Magento側の設定変更

エンジンの設定はStores - Configuration - Catalog - Catalog Searchの中にあります。

Use system valueのチェックを外しElasticsearchを選択します。

このボタンで接続確認を行います。

以下の表示が出れば接続確認OKです。

Save Configします。

これだけだと何も出力されないので、キャッシュとインデックスを作り直します。
