[OpenSearch] OpenSearch 설치

반응형

OpenSearch

회사에서 오픈서치를 적용하게되어 공부겸 높은 이해도를 높이기 위해 글을 작성해 봅니다.

 

OpenSearch 설치

opensearch.yaml 작성

• 도커로 실행하기 위해서 yaml 파일을 작성해 줍니다.
• 연습 용이기 때문에 node 는 하나만 지정해 줍니다.
• opensearch-node1: 노드1 서버를 설치하기 위한 설정
• opensearch-dashboards: GUI 를 위한 대시 보드
• OPENSEARCH_INITIAL_ADMIN_PASSWORD=Root123#@! : 어드민 password 지정

정상적으로 오픈서치를 설치하고 접근하였습니다.

실무에서는 노드당 최대 샤드가 지정되어 있기 때문에 필요에 따라서 노드수를 늘리거나 샤드수를 늘려야 합니다.
