[前回] Elasticsearchクラスタ検証(1): Hyper-VにAlmaLinuxサーバー3台構築
はじめに
前回用意した、AlmaLinuxサーバー3台に、
同じ手順でElasticsearch 8.xを導入します。
-
AlmaLinux8-1(node1) -
AlmaLinux8-2(node2) -
AlmaLinux8-3(node3)
仮想マシンAlmaLinux8-1(node1)に、Elasticsearchパッケージ導入
端末を開き、管理者権限で以下実行。
- EslasticsearchリポジトリのGPG keyをインポート
# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
- rpm repositoryを登録
/etc/yum.repos.d/elasticsearch.repo
[elasticsearch]
name=Elasticsearch repository for 8.x packages
baseurl=https://artifacts.elastic.co/packages/8.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=0
autorefresh=1
type=rpm-md
- Elasticsearchパッケージをインストール
# dnf check-update --enablerepo=elasticsearch
# dnf install elasticsearch --enablerepo=elasticsearch -y
Elasticsearchの設定
- Elasticsearchをサービスとして有効化
# systemctl enable elasticsearch
Created symlink /etc/systemd/system/multi-user.target.wants/elasticsearch.service → /usr/lib/systemd/system/elasticsearch.service.
- Elasticsearch設定ファイルを開き、index自動作成設定を最終行に追加
/etc/elasticsearch/elasticsearch.yml
action.auto_create_index: .monitoring*,.watches,.triggered_watches,.watcher-history*,.ml*
Elasticsearchのユーザーパスワードをリセット
- Elasticsearchを起動
# systemctl start elasticsearch
- elasticユーザーのパスワードをリセット
# /usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic -i
This tool will reset the password of the [elastic] user.
You will be prompted to enter the password.
Please confirm that you would like to continue [y/N]y
Enter password for [elastic]:
Re-enter password for [elastic]:
Password for the [elastic] user successfully reset.
Elasticsearchの起動確認
# curl -k -u elastic https://localhost:9200
Enter host password for user 'elastic':
{
"name" : "node1",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "ksn5SqyVRQK4I1RWKKp95w",
"version" : {
"number" : "8.3.3",
"build_flavor" : "default",
"build_type" : "rpm",
"build_hash" : "801fed82df74dbe537f89b71b098ccaff88d2c56",

"minimum_index_compatibility_version" : "7.0.0"
},
"tagline" : "You Know, for Search"
}
仮想マシンAlmaLinux8-2(node2)に、Elasticsearch導入
手順は上記と同じ。
仮想マシンAlmaLinux8-3(node3)に、Elasticsearch導入
手順は上記と同じ。
おわりに
Elasticsearchを、サーバー3台にそれぞれ導入しました。
次回はクラスタ設定を行います。お楽しみに。
