Follow the next steps to install Solr 9.0 on your latest Debian Servers
Step 1: System Update
Before diving into the installation process, it’s essential to ensure your Debian 11 system is up-to-date. Open a terminal and run the following commands:
samm@solr:~$ sudo apt-get update
samm@solr:~$ sudo apt-get upgrade
Step 2: Install Required Packages
Apache Solr requires Java to run. Install OpenJDK 11, a recommended version, using the following command:
samm@solr:~$ sudo apt install default-jdk gnupg2 apt-transport-https wget -y
Check the installed java version
samm@solr:~$ java -version
openjdk version "11.0.16" 2022-07-19
OpenJDK Runtime Environment (build 11.0.16+8-post-Debian-1deb11u1)
OpenJDK 64-Bit Server VM (build 11.0.16+8-post-Debian-1deb11u1, mixed mode, sharing)
Step 3: Install Solr 9.1 on Debian 11
After successfully installing the required packages, proceed to navigate to the Apache Solr official download page to obtain the URL for the latest version. Once you’re there, in your terminal, employ ‘wget’ to initiate the download of the package.
samm@solr:~$ wget https://dlcdn.apache.org/solr/solr/9.1.0/solr-9.1.0.tgz
Now extract the Apache Solr service installer shell script from the downloaded Solr archive file and run the installer using the following commands.
samm@solr:~$ tar xzf solr-9.1.0.tgz solr-9.1.0/bin/install_solr_service.sh --strip-components=2
samm@solr:~$ sudo bash ./install_solr_service.sh solr-9.1.0.tgz

Step 4: Manage Solr Service
samm@solr:~$ sudo systemctl enable solr
samm@solr:~$ sudo systemctl start solr
samm@solr:~$ sudo systemctl status solr

Step 5: Create First Solr Core (Collection)
A core serves as a fundamental unit of Solr, encompassing both the configuration and data tailored for a specific index. Now, let’s proceed to create a core and name it ‘sammlinux’. Create the first collection in Apache Solr using the following command.
samm@solr:~$ sudo su - solr -c "/opt/solr/bin/solr create -c sammlinux"
Sample output:
Created new core 'sammlinux'
Step 6: Access Solr Admin Panel
By default, Solr runs on port 8983. Upon accessing the Solr port in your web browser, you’ll be directed to a Solr dashboard where you can explore its features and functionalities.
http://you-domain-solr:8983/
Here, you can review the statistics of the collection you created in the previous steps, named ‘sammlinux’. To do this, simply click on the ‘Core Selector’ located in the left sidebar, and then choose the collection you’ve created.
Step 7: Indexing Data
To make the most of Solr’s search capabilities, you need to index your website’s data. Use Solr’s Data Import Handler (DIH) or APIs to populate the index.
Step 8: Integrate Solr with Your Website
Transitioning to the integration phase, connect Solr seamlessly with your website’s search functionality by utilizing either Solr’s RESTful APIs or the client libraries accessible in a range of programming languages.
Step 9: Monitor and Optimize
As you proceed, make sure to consistently monitor your Solr instance to maintain peak performance. Make effective use of Solr’s inherent metrics and monitoring tools. Additionally, contemplate the integration of caching mechanisms and query optimization strategies to enhance search speed.
Conclusion
Incorporating Apache Solr 9.1 into your Debian 11 environment can significantly enhance your website’s search functionality. By following this comprehensive guide, you’ve successfully installed, configured, and integrated Solr, empowering you to take control of your website’s search capabilities. Stay proactive in monitoring and optimizing your Solr instance to reap the full benefits of this powerful search platform.
