Install Apache Solr on Debian 11

In this tutorial, we will show you how to install Apache Solr on Debian 11. For those of you who didn’t know, Apache Solr is an open-source enterprise search platform, written in Java. Apache Solr is widely used for enterprise search and analytics use cases and has an active development community and regular releases.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the Apache Solr on a Debian 11 (Bullseye).

Install Apache Solr on Debian 11 Bullseye

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt upgrade
sudo apt install default-jre gnupg2 apt-transport-https wget

Step 2. Installing Java.

Run the following command to install Java to your Debian system:

sudo apt install default-jre default-jdk

You can verify the installation of Java by running the command below:

java -version

Step 3. Installing Apache Solr on Debian 11.

Now we download the latest version of Apache Solr from the official page:

wget https://downloads.apache.org/lucene/solr/8.9.0/solr-8.9.0.tgz

Next, extract the downloaded file with the following command below:

tar xzf solr-8.9.0.tgz

To install Apache Solr on your Debian system, you will have to execute the following terminal command:

bash solr-8.9.0/bin/install_solr_service.sh solr-8.9.0.tgz

After installed, you can simply use the following commands to start, stop, restart, and check the status of the Solr service:

sudo systemctl start solr
sudo systemctl stop solr
sudo systemctl status solr

Step 4. Create Apache Solr Collection.

Now we create the first collection in Apache Solr using the following command below:

su - solr -c "/opt/solr/bin/solr create -c idrootwell -n data_driven_schema_configs"

Output:

Created new core 'idrootwell'
