항해99 실전 프로젝트 (21일차)

Redis 예매 테이블 적용

인덱싱 색인, ElasticSearch, Redis Cache 전략

• 100만명… 500만명… 1000만명 몰릴 때 확장 할 수 있는지?, 어떻게 확장 할건지?

Spring boot에서 jedis를 사용 할려고 했지만 빈 충돌이나고, jedis 1개로 사용해도 기존에 구현된 refreshToken을 다시 구현 야해서 ElasticSearch로 확인

ElasticSearch 적용

ElasticSearch:8.12.1
Spring Boot 3.2.2
Spring ElasticSearch 3.2.2

• build.gradle에 추가

implementation 'org.springframework.boot:spring-boot-starter-data-elasticsearch'

• Configuration 추가

@Configuration  
@EnableElasticsearchRepositories  
public class ElasticSearchConfig extends ElasticsearchConfiguration {  
    @Override  
    public ClientConfiguration clientConfiguration() {  
       return ClientConfiguration.builder()  
          .connectedTo("localhost:9200")  
          .build();  
    }  
}

• 로컬환경에서는 http를 사용하기에 Docker에서 Security 비활성화
  config 파일 간 후에 밑의 echo로 덮어씌움

• config 폴더로 이동

cd config

• echo로 설정 업데이트

echo "cluster.name: docker-cluster
network.host: 0.0.0.0
