elasticsearch.hosts: "192.168.0.50:9200" <-- 같은 서버내 있다면 localhost:9200 설정

@시작과 종료

systemctl start kibana.service

systemctl stop kibana.service

@memory , file unlimited 설정

vi /etc/security/limits.conf

elasticsearch hard memlock unlimited
elasticsearch soft memlock unlimited
elasticsearch hard nofile 65536
elasticsearch soft nofile 65536
elasticsearch hard nproc 65536
elasticsearch soft nproc 65536

@서비스 시작시 memory lock -> 무한 설정

vi /usr/lib/systemd/system/elasticsearch.service

[Service]

LimitMEMLOCK=infinity <-- 추가

위 설정을 하지 않는다면

memory locking requested for elasticsearch process but memory is not locked 

오류가 발생 할 수 있음

@환경설정

vi  /etc/elasticsearch/elasticsearch.yml

최초 구동을 위해서는 아래 3가지는 반드시 설정 해줘야함 

node.name:master

discovery.seed_hosts: ["192.168.0.50","::1"]  <-- 서버 아이피 설정

cluster.initial_master_nodes: ["master"]  <-- 마스터 노드명

위 설정을 하지 않는다면

 the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

@실행 / 종료
