Insight: Tutorial To Install Elasticsearch on CentOS 8

Elasticsearch, developed in Java is a search engine based on the Lucene library that provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents.

As elasticsearch is not available in the standard CentOS 8 repositories, you need to install it from the Elasticsearch RPM repository.

sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

Now, Open your text editor and create the repository file the /etc/yum.repos.d/ directory:

sudo nano /etc/yum.repos.d/elasticsearch.repo

Paste the following content:

/etc/yum.repos.d/elasticsearch.repo

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
Save the file and close your text editor.

sudo dnf install elasticsearch

sudo systemctl enable elasticsearch.service --now
