With years of unparalleled expertise in server architecture and management, \u0141ukasz is widely regarded as the king of servers. His passion for technology and commitment to excellence have been the driving forces behind NetCloud24’s success, establishing it as a world-class hosting provider originating from Poland.<\/p>\n<\/div>\nIntroduction to Apache Solr<\/h2>\n
Apache Solr<\/strong> is a powerful, open-source enterprise search platform built on Apache Lucene. It’s widely used for full-text search, real-time indexing, dynamic clustering, and rich document handling. If you need to add powerful search capabilities to your applications, Solr is an excellent choice, offering scalability, fault tolerance, and a comprehensive feature set. This tutorial will guide you through the process of installing it on your AlmaLinux 9 server.<\/p>\n
\nStep 1: System Update<\/h2>\n
First, it’s always a good practice to update your system’s package index to ensure you have the latest security patches and software versions. Connect to your server via SSH and run:<\/p>\n
sudo dnf update -y<\/code><\/pre>\n
\nStep 2: Install Java<\/h2>\n
Apache Solr is a Java-based application and requires a Java Runtime Environment (JRE) to run. AlmaLinux 9 repositories include OpenJDK, which we will install.<\/p>\n
sudo dnf install java-11-openjdk -y<\/code><\/pre>\nOnce the installation is complete, you can verify it by checking the Java version:<\/p>\n
java -version<\/code><\/pre>\nThe output should confirm that OpenJDK version 11 is successfully installed.<\/p>\n
\nStep 3: Download and Install Apache Solr<\/h2>\n
Next, you will download the latest version of Apache Solr from the official website. You can find the latest version on the Apache Solr Downloads page<\/a>. As of this tutorial, a recent version is 9.x.<\/p>\nUse `wget` to download the Solr archive to your `\/opt` directory:<\/p>\n
cd \/opt\r\nsudo wget https:\/\/dlcdn.apache.org\/solr\/solr\/9.6.1\/solr-9.6.1.tgz<\/code><\/pre>\nNote: Please check the official downloads page for the very latest version and replace the URL accordingly.<\/em><\/p>\nAfter downloading the archive, you will use the installation script that is included within it. First, extract the installation script:<\/p>\n
sudo tar xzf solr-9.6.1.tgz solr-9.6.1\/bin\/install_solr_service.sh --strip-components=2<\/code><\/pre>\nNow, run the installer script. This script will create a dedicated `solr` user and install Solr as a service.<\/p>\n
sudo bash .\/install_solr_service.sh solr-9.6.1.tgz<\/code><\/pre>\nThe installer will automatically start the Solr service.<\/p>\n
\nStep 4: Manage the Solr Service and Firewall<\/h2>\n
The installer has configured Solr to run as a service under `systemd`. You can manage it with the standard `systemctl` commands:<\/p>\n
\n- Check the status:<\/strong>\n
sudo systemctl status solr<\/code><\/pre>\n<\/li>\n- Stop the service:<\/strong>\n
sudo systemctl stop solr<\/code><\/pre>\n<\/li>\n- Start the service:<\/strong>\n
sudo systemctl start solr<\/code><\/pre>\n<\/li>\n- Enable on boot:<\/strong>\n
sudo systemctl enable solr<\/code><\/pre>\n<\/li>\n<\/ul>\nBy default, Solr runs on port 8983<\/strong>. You need to open this port in your firewall to allow external access to the Solr web interface.<\/p>\nsudo firewall-cmd --permanent --add-port=8983\/tcp\r\nsudo firewall-cmd --reload<\/code><\/pre>\n
\nStep 5: Access the Solr Web Admin Interface<\/h2>\n
With the service running and the firewall port open, you can now access the Solr admin panel. Open your web browser and navigate to:<\/p>\n
http:\/\/your_server_ip:8983\/solr<\/code><\/p>\nYou should see the Solr dashboard, which allows you to manage your collections, run queries, and monitor the health of your Solr instance.<\/p>\n
