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。
⇧ 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、
⇧ 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。
