Elasticsearch is a search engine based on the Lucene library. It provides a distributed, multi-tenant full-text search engine with an HTTP web interface and schema-free JSON documents. In this guide, we will cover the installation of Elasticsearch 8.x/7.x/6.x on Fedora 37/36/35/34/33. Elasticsearch is a highly scalable open-source analytics engine and full-text search. With Elasticsearch, you can store, search, and analyze big volumes of data faster and in near real-time.
Some key features of Elasticsearch include:
- Distributed and highly available search engine: Elasticsearch is designed to be run on a cluster of machines, with each instance called a “node”. This allows for horizontal scalability and high availability of the search functionality.
- Real-time search and analytics: Elasticsearch can search and analyze large volumes of data in near real-time, making it suitable for use cases such as log analysis, business intelligence, and website search.
- Faceted search and filtering: Elasticsearch allows for faceting, which is a way to aggregate data based on certain criteria, and filtering, which allows to narrow down search results based on certain conditions.
- Support for plugins and custom implementations:It has a plugin framework that allows for the addition of custom functionality and integration with other systems.
Follow the steps provided in this article to have a working installation of Elasticsearch 8/7/6 on Fedora 37/36/35/34/33/32.
For multi-node cluster, refer to:
Step 1: Install Java on Fedora
Elasticsearch depends on Java, you need it installed on your machine prior to installing Elasticsearch on Fedora. Default upstream version of OpenJDK can be installed on Fedora by running the commands:
sudo dnf install lsof java-17-openjdk java-17-openjdk-devel -yAfter the installation of Java, you can quickly confirm the version using the following command:
$ java -version openjdk version "17.0.5" 2022-10-18 OpenJDK Runtime Environment (Red_Hat-17.0.5.0.8-1.fc37) (build 17.0.5+8) OpenJDK 64-Bit Server VM (Red_Hat-17.0.5.0.8-1.fc37) (build 17.0.5+8, mixed mode, sharing)
Step 2: Install Elasticsearch on Fedora
After installing Java JDK, add Elasticsearch repository to your Fedora system.
1. Import GPG Key
sudo rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
2. Add Repository
For Elasticsearch 8.x
cat <<EOF | sudo tee /etc/yum.repos.d/elasticsearch.repo
[elastic-8.x]
name=Elastic 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
EOFFor Elasticsearch 7.x
cat <<EOF | sudo tee /etc/yum.repos.d/elasticsearch.repo
[elasticsearch-7.x]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/oss-7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md
EOF
For Elasticsearch 6.x.
cat <<EOF | sudo tee /etc/yum.repos.d/elasticsearch.repo
[elasticsearch-6.x]
name=Elasticsearch repository for 6.x packages
baseurl=https://artifacts.elastic.co/packages/oss-6.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md
EOF3. Install Elasticsearch on Fedora
Elasticsearch repository is ready for use. You can install Elasticsearch using the command below:
sudo dnf install elasticsearch-oss||sudo dnf install elasticsearch
Hit the y key to start installation of Elasticsearch on Fedora:

}Step 3: Install Kibana on Fedora
Kibana lets you visualize your Elasticsearch data and navigate the Elastic Stack. Install it after adding the repository using the command:
sudo dnf install -y kibana-oss||sudo dnf install -y kibanaGenerate an enrollment token for Kibana (ELK 8)
sudo /usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibanaAfter a successful installation, configure Kibana
$ sudo vi /etc/kibana/kibana.yml server.host: "0.0.0.0" server.name: "kibana.example.com" elasticsearch.url: "http://localhost:9200"
Change other settings as desired then start Kibana service:
sudo systemctl enable --now kibanaAccess http://ip-address:5601 to open Kibana Dashboard:
If you have an active firewall, you’ll need to allow access to Kibana port:
sudo firewall-cmd --add-port=5601/tcp --permanent
sudo firewall-cmd --reloadFor Ubuntu users, check
