Elasticsearch Install
LDAP 연동 테스트용으로 설치 진행
1. CentOS 7 설치
- Hyper-V 로 구성
- 2세대, 설정에서 보안부팅 사용 X
- Root 계정 외 별도 계정사용(root로 Elasticsearch 실행불가)
2. 네트워크 설정 (고정IP)
- 계정 로그인 후 이더넷 장치 확인
| [redplug@localhost ~]$ nmcli d DEVICE TYPE STATE CONNECTION eth0 ethernet disconnected eth0 lo loopback unmanaged -- |
- 고정IP 설정
|
[redplug@localhost ~]$ sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0 # 네트워크 재시작 systemctl restart network |
3. Elasticsearch 설치
- Import the Elasticsearch PGP Key
| [redplug@localhost ~]$ sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch [redplug@localhost ~]$ |
- Installing from the RPM repository
레파지토리 추가
|
[redplug@localhost /]$ sudo vi /etc/yum.repos.d/elasticsearch.repo [elasticsearch-7.x]

- 실행 확인
하기와 같이 화면이 노출되면 정상적으로 실행
| [redplug@localhost /]$ curl -XGET 127.0.0.1:9200 { "name" : "localhost.localdomain", "cluster_name" : "elasticsearch", "cluster_uuid" : "KR5xkBUJRwqrBdETyAJoqg", "version" : { "number" : "7.3.0", "build_flavor" : "default", "build_type" : "rpm", "build_hash" : "de777fa", "build_date" : "2019-07-24T18:30:11.767338Z", "build_snapshot" : false, "lucene_version" : "8.1.0", "minimum_wire_compatibility_version" : "6.8.0", "minimum_index_compatibility_version" : "6.0.0-beta1" }, "tagline" : "You Know, for Search" } [redplug@localhost /]$ |
