docker 로 elasticsearch 7 설치

환경 설정

sudo apt-get install docker-compose
 
sudo sysctl -w fs.file-max=262114
sudo sysctl -w  vm.max_map_count=1048575

 

디렉토리 구성

3개의 nodes 로 구성하고, 각각의 LOCAL 저장소 위치를 다음과 같이 사용한다면

• /home/windbird/opt/elasticsearch/data/es01
• /home/windbird/opt/elasticsearch/data/es02   
• /home/windbird/opt/elasticsearch/data/es03

각각의 디렉토리 생성 후 아래와 같이 권한 설정함

chown -R 1000:root /home/windbird/opt/elasticsearch/data/es01
chown -R 1000:root /home/windbird/opt/elasticsearch/data/es02
chown -R 1000:root /home/windbird/opt/elasticsearch/data/es03

 

docker-compose.yml 

아래의 ES_JAVA_OPTS 에서 node 마다 16GB 메모리를 사용하도록 설정했는데, 필요에 따라 조정한다.
