Elasticsearch、Logstash、Kibanaをインストールしたので起動確認

前回、

⇧ Elasticsearch、Logstash、Kibanaをインストールしてみたのですが、何故か、WSL 2（Windows SubSystem for Linux 2）のUbuntuを再起動したら、Elasticsearchのサービスが起動していなかったので、起動しようと試みたのですが、

⇧ 起動しない...

Elasticsearchのログを確認してみた。

⇧ メモリー関係でエラーになってるっぽい。

stackoverflow.com

⇧ 上記サイト様を参考に、設定を行う。

sudo vi /etc/elasticsearch/jvm.options

変更して、保存。

Elasticsearchを再起動。

⇧ 起動できました。

Elasticsearch 8 からは、セキュリティの仕様が変わったらしいので、

qiita.com

⇧ 上記サイト様を参考に、パスワードを更新します。

sudo /usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic -i

Elasticsearchへの疎通確認。

curl -k -u elastic https://10.255.255.16:9200

Logstashを自動起動されるようにしておきます。

sudo systemctl enable logstash.service    

sudo systemctl start logstash.service    

sudo systemctl status logstash.service

とりあえず、Elasticsearch、Logstash、Kibanaの各サービスが起動されるようにはなったということで。

WSL 2（Windows SubSystem for Linux 2）の問題なのか、Elasticsearchのサービスが普通に動いてくれないのが気になりますな...

そもそも、/etc/elasticsearch/jvm.optionsのメモリの設定がコメントアウトされていたり、分からんことが多いですな...

毎度モヤモヤ感が半端ない...

今回はこのへんで。
