How to install Elasticsearch on Rocky Linux 9.2
To Install Elasticsearch On Rocky Linux 9.2
Introduction:
Elasticsearch is a free, open-source, distributed search and analytics engine capable of handling large amounts of data that is used for real-time full-text searches in applications where a large amount of data needs to be analyzed. It is very popular due to its usability, powerful features, and scalability. It supports RESTful API with an HTTP URI to manipulate data. Elasticsearch is easy to use, offering features such as automatic node recovery, improved security, scalability and resiliency, automatic data balancing, and more.
Procedure Steps:
Step 1: Check the OS version by using the following command
[root@Linuxhelp ~]# cat /etc/os-release
NAME="Rocky Linux"
VERSION="9.2 (Blue Onyx)"
ID="rocky"
ID_LIKE="rhel centos fedora"
VERSION_ID="9.2"
PLATFORM_ID="platform:el9"
PRETTY_NAME="Rocky Linux 9.2 (Blue Onyx)"
ANSI_COLOR="0;32"
LOGO="fedora-logo-icon"
CPE_NAME="cpe:/o:rocky:rocky:9::baseos"
HOME_URL="https://rockylinux.org/"
BUG_REPORT_URL="https://bugs.rockylinux.org/"
SUPPORT_END="2032-05-31"
ROCKY_SUPPORT_PRODUCT="Rocky-Linux-9"
ROCKY_SUPPORT_PRODUCT_VERSION="9.2"
REDHAT_SUPPORT_PRODUCT="Rocky Linux"
REDHAT_SUPPORT_PRODUCT_VERSION="9.2"
Step 2: Elastic Search is a Java-based application, so Java must be installed on your server. If not installed, you can install it by running the following command
[root@Linuxhelp ~]# dnf install java-11-openjdk-devel

Complete!
Step 3: After the installation, verify the Java version by using the following command
[root@Linuxhelp ~]# java -version
openjdk version "11.0.21" 2023-10-17 LTS
OpenJDK Runtime Environment (Red_Hat-11.0.21.0.9-1) (build 11.0.21+9-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.21.0.9-1) (build 11.0.21+9-LTS, mixed mode, sharing)
Step 4: By default, Elasticsearch is not included in the Rocky Linux default repository, so we will need to create a repository for it. For that first download and import the GPG key with the following command
[root@Linuxhelp ~]# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
Step 5: create an Elasticsearch repo by using the following command
[root@Linuxhelp ~]# vim /etc/yum.repos.d/elasticsearch.repo
Add the following lines:
[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
Step 6: With the created repository file, we can now install Elasticsearch by using the following command
[root@Linuxhelp ~]# dnf install elasticsearch

Step 7: After installing Elasticsearch, edit the Elasticsearch main configuration file by using the following command
[root@Linuxhelp ~]# vi /etc/elasticsearch/elasticsearch.yml
Change the following lines:
cluster.name: Linuxhelp.com
node.name: node-1
path.data: /var/lib/elasticsearch
network.host: 127.0.0.1
Step 8: Enable and Start the Elasticsearch service by using the following command.
[root@Linuxhelp ~]# systemctl enable elasticsearch
Created symlink /etc/systemd/system/multi-user.target.wants/elasticsearch.service → /usr/lib/systemd/system/elasticsearch.service.
[root@Linuxhelp ~]# systemctl start elasticsearch
Step 9: Check the status of the Elasticsearch service by using the following command.
[root@Linuxhelp ~]# systemctl status elasticsearch

"cluster_name" : "Linuxhelp.com",
"cluster_uuid" : "-GQDdChgQL-IUo2VNS6yMQ",
"version" : {
"number" : "7.17.14",
"build_flavor" : "default",
"build_type" : "rpm",
"build_hash" : "774e3bfa4d52e2834e4d9d8d669d77e4e5c1017f",

"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
With the above response, Elasticserach is working properly on port 9200
Conclusion:
We have reached the end of this article. In this guide, we have walked you through the steps required to install Elasticsearch on Rocky Linux 9.2. Your feedback is much welcome.

A
Key configurations include setting the cluster name, configuring network settings, specifying data and log paths, and defining memory settings based on your system's available resources. Security and node roles are also important considerations.
Q
How do I install Java for Elasticsearch?
A
You should install a compatible version of Java (typically OpenJDK) before installing Elasticsearch. Use your system's package manager to install it.
Q
What is Elasticsearch, and why would I want to install it?
A
Elasticsearch is a powerful, open-source search and analytics engine. You might want to install it to build a robust search and analytics solution for your data, such as log and event data analysis, full-text search, and more.
