Prerequisites

• An AlmaLinux 9 server with root access
• Java Development Kit (JDK) installed (version 8 or later)
• Basic knowledge of Linux commands

Step 1: Update Your System

Start by updating your package index and upgrading any existing packages:

sudo dnf update -y

Step 2: Install Java

Apache Solr requires Java to run. Install OpenJDK by executing the following command:

sudo dnf install java-11-openjdk -y

Verify the installation of Java:

java -version

Step 3: Download Apache Solr

Go to the Apache Solr downloads page and get the latest version. Use the following commands to download it:

wget https://downloads.apache.org/lucene/solr/9.2.1/solr-9.2.1.tgz

Extract the downloaded archive:

tar xzf solr-9.2.1.tgz

Step 4: Install Apache Solr

Change to the Solr directory and run the installation script:

cd solr-9.2.1
sudo bin/install_solr_service.sh solr-9.2.1.tgz

Step 5: Start Apache Solr

After the installation is complete, start the Solr service:

sudo systemctl start solr

Enable Solr to start on boot:

sudo systemctl enable solr

Step 6: Access Apache Solr

Once the service is running, you can access the Solr admin interface by navigating to http://your_server_ip:8983/solr in your web browser. Replace your_server_ip with the actual IP address of your server.

Step 7: Create a Solr Core

You can create a new core by using the following command:

sudo -u solr /opt/solr/bin/solr create -c mycore

This command creates a core named "mycore." You can manage your cores from the Solr admin interface.
