How to install Elasticsearch on Oracle Linux 9.3
To Install ElasticSearch On Oracle Linux 9.3
Introduction
Elasticsearch is a cost-effective, open-source, distributed search and analytics engine that is proficient in managing substantial quantities of data for real-time full-text searches in applications requiring comprehensive data analysis. Its popularity stems from its user-friendly interface, robust functionalities, and scalability. Elasticsearch facilitates data manipulation through a RESTful API with an HTTP URI. Its user-friendly features include automatic node recovery, enhanced security measures, scalability and resilience, automated data balancing, and additional capabilities.
Procedure Steps:
Step 1: Check the OS version by using the below command
[root@linuxhelp ~]# cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="9.3"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="9.3"
PLATFORM_ID="platform:el9"
PRETTY_NAME="Oracle Linux Server 9.3"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:oracle:linux:9:3:server"
HOME_URL="https://linux.oracle.com/"
BUG_REPORT_URL="https://github.com/oracle/oracle-linux"
ORACLE_BUGZILLA_PRODUCT="Oracle Linux 9"
ORACLE_BUGZILLA_PRODUCT_VERSION=9.3
ORACLE_SUPPORT_PRODUCT="Oracle Linux"
ORACLE_SUPPORT_PRODUCT_VERSION=9.3
Step 2: Elastic Search is a Java-based application, so Java must be installed on your server. If not installed, you can install it using the below command
[root@linuxhelp ~]# dnf install java-11-openjdk-devel

Complete!
Step 3: After the installation, verify the Java version by using the below command
[root@linuxhelp ~]# java -version
openjdk version "11.0.23" 2024-04-16 LTS
OpenJDK Runtime Environment (Red_Hat-11.0.23.0.9-3.0.1) (build 11.0.23+9-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.23.0.9-3.0.1) (build 11.0.23+9-LTS, mixed mode, sharing)
Step 4: By default, Elasticsearch is not included in the Oracle Linux default repository, so we will need to create a repository for it. For that first download and import the GPG key by using the below command
[root@linuxhelp ~]# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
Step 5: Create an Elasticsearch repo by using the below command
[root@linuxhelp ~]# vim /etc/yum.repos.d/elasticsearch.repo
Add those following Line
[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 below command
[root@linuxhelp ~]# dnf install elasticsearch
Elasticsearch repository for 7.x packages 9.6 MB/s | 61 MB 00:06

sudo systemctl daemon-reload
sudo systemctl enable elasticsearch.service
### You can start elasticsearch service by executing
sudo systemctl start elasticsearch.service

Step 7: After installing Elasticsearch, edit the Elasticsearch main configuration file by using the below command
[root@linuxhelp ~]# vim /etc/elasticsearch/elasticsearch.yml
Add those following Lines
cluster.name: Linuxhelp.com
node.name: node-1
network.host: 127.0.0.1
Step 8: Enable the Elasticsearch service by using the below command
[root@linuxhelp ~]# systemctl enable elasticsearch.service
Synchronizing state of elasticsearch.service with SysV service script with /usr/lib/systemd/systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install enable elasticsearch
Created symlink /etc/systemd/system/multi-user.target.wants/elasticsearch.service → /usr/lib/systemd/system/elasticsearch.service.
Step 9: Check the status of the Elasticsearch service by using the below command
[root@linuxhelp ~]# systemctl status elasticsearch.service
○ elasticsearch.service - Elasticsearch
Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; preset: disabled)
Active: inactive (dead)
Docs: https://www.elastic.co
Step 10: Start the Elasticsearch service by using the below command
[root@linuxhelp ~]# systemctl start elasticsearch.service
Step 11: Again check the status Elasticsearch service by using the below command
[root@linuxhelp ~]# systemctl status elasticsearch.service
● elasticsearch.service - Elasticsearch

Step 12: Verify Elasticsearch by using the below command
[root@linuxhelp ~]# curl -X GET 'http://localhost:9200'
{
"name" : "node-1",
"cluster_name" : "Linuxhelp.com",
"cluster_uuid" : "umEWzl-QSCOpIWZX4daLhQ",
"version" : {
"number" : "7.17.21",
"build_flavor" : "default",
"build_type" : "rpm",
"build_hash" : "d38e4b028f4a9784bb74de339ac1b877e2dbea6f",
"build_date" : "2024-04-26T04:36:26.745220156Z",
"build_snapshot" : false,

"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 Oracle Linux 9.3. Your feedback is much welcome.
Q
How do I start and manage the Elasticsearch service?
A
You can use your system's service manager to start and manage the Elasticsearch service. Common commands include systemctl start elasticsearch (systemd) or service elasticsearch start (SysV init).
Q
How can I access the Elasticsearch web interface (Kibana)?
A
To access the Elasticsearch web interface (Kibana), you need to install Kibana separately and configure it to connect to your Elasticsearch instance. Configuration settings are typically found in the Kibana configuration file.
Q
What are the important Elasticsearch configurations to consider?
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
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 can 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.
