yum을 이용할 repository 추가

X

user@localhost:~

[root@localhost]# echo '[elasticsearch]
name=Elasticsearch repository for 8.x packages
baseurl=https://artifacts.elastic.co/packages/8.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=0
autorefresh=1
type=rpm-md' > /etc/yum.repos.d/elasticsearch.repo

 

현재 기준으로 표준 설치는 elasticsearch 8.6.2 이지만, elastalert의 plugin 버전을 맞춘겁니다.

설치 시 꼭 하단 링크의 elastalert의 버전과 호환되는 버전으로 설치하세요

elastalert-plugin: https://github.com/karql/elastalert-kibana-plugin/releases
