 : Elasticsearch 1.6.0 Single Cluster 설치 및 환경 구축

하나의 노드에 설치 및 환경 구축이 끝났다는 가정하에 진행합니다.

1. elasticsearch 디렉터리를 압축

$ sudo tar -cvzf ./elasticsearch-1.6.0.tar.gz ./elasticsearch-1.6.0
 

2. 압축 파일에 소유 권한 부여

$ sudo chown -R hadoop-user:hadoop ./elasticsearch-1.6.0.tar.gz
 

3. 클러스터링 된 노드에 압축 파일을 배포

$ scp ./elasticsearch-1.6.0.tar.gz hadoop-user@secondary:~/
elasticsearch-1.6.0.tar.gz                                                         100%   27MB  27.1MB/s   00:00
 

* 해당하는 노드의 수만큼 배포를 진행합니다.

* 위 과정을 진행하려면 아래와 같은 작업이 사전에 요구됩니다.

 : ssh 공개 키 생성 및 분배

4. elasticsearch.yml 설정 파일

 4-1. elasticsearch.yml 편집

  : vi /usr/local/elasticsearch/config/elasticsearch.yml

$ vi ./config/elasticsearch.yml
 

 4-2. 다음과 같이 cluster.name 부분을 주석 해제하고 이름을 지정합니다.

  : 편집 전

################################### Cluster ###################################
 
# Cluster name identifies your cluster for auto-discovery. If you're running
# multiple clusters on the same network, make sure you're using unique names.
#
#cluster.name: elasticsearch
 

  : 편집 후

################################### Cluster ###################################
 
# Cluster name identifies your cluster for auto-discovery. If you're running
# multiple clusters on the same network, make sure you're using unique names.
#
cluster.name: elasticsearch
 

5. elasticsearch를 실행합니다.
