CentOS 7 ElasticSearch 설치

Posted by Albert 802Day 18Hour 53Min 59Sec ago [2023-02-07]

간단히 centos 상 elasticsearch 설치해보았다.

1. [kafka@localhost kafka_2.13-3.3.2]$ sudo vi /etc/yum.repos.d/elasticsearch.repo

아래 내용 추가하고 wq

7x 버전 설치시

[elasticsearch-7.x]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

8x 버전 설치시

[elasticsearch-8.x]
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=1
autorefresh=1
type=rpm-md

2. 위 repo설정 마쳤으면 설치시작

[kafka@localhost ~]$ sudo yum install elasticsearch -y

=============================================================================

Verifying  : elasticsearch-7.17.9-1.x86_64 Installed:
elasticsearch.x86_64 0:7.17.9-1

Complete!

3. 설치 완료되면 elasticsearch 외부접속설정

1. sudo vi /etc/elasticsearch/elasticsearch.yml

/9200 으로 아래 내용을 찾는다

====================================

'network.host: 192.168.0.1

'network.host: localhost

network.host: 0.0.0.0

'

' By default Elasticsearch listens for HTTP traffic on the first free port it

' finds starting at 9200. Set a specific HTTP port here:

'

http.port: 9200

'

' For more information, consult the network module documentation.

'

...

' --------------------------------- Discovery ----------------------------------

'

' Pass an initial list of hosts to perform discovery when this node is started:

' The default list of hosts is ["127.0.0.1", "[::1]"]

'

'discovery.seed_hosts: ["host1", "host2"]

'

' Bootstrap the cluster using an initial set of master-eligible nodes:

'

cluster.initial_master_nodes: ["node-1", "node-2"]

'

' For more information, consult the discovery and cluster formation module documentation.

'

이렇게 하여 3곳 수정하고 elasticsearch 서비스 재시작 하면 된다.

1.network.host: 0.0.0.0, 2.http.port: 9200 3.cluster.initial_master_nodes: ["node-1", "node-2"]

서비스 실행

========================

sudo systemctl enable elasticsearch

sudo systemctl start elasticsearch

sudo systemctl status elasticsearch

========================

4. curl 확인

    "name" : "localhost.localdomain",
    "cluster_name" : "elasticsearch",
    "cluster_uuid" : "6AU70llYRXKAvp6gXzT5aQ",

    },
    "tagline" : "You Know, for Search"
}
