How to Install Apache Solr on OpenBSD

Apache Solr is a powerful search platform that can be used to search, index, and analyze large amounts of data. In this tutorial, we will walk you through the process of installing Apache Solr on OpenBSD.

Prerequisites

1. OpenBSD Operating System
2. Admin/root privileges

Step 1 – Install Java

Before we start installing Solr on OpenBSD, we need to install Java because Solr requires Java to run.

First, check if Java is installed on your OpenBSD by running the following command:

$ java -version

If you get an output saying command not found, then it means Java is not installed on your system.

To install OpenJDK 8, run the following commands:

$ doas pkg_add openjdk8

After the installation, verify the installation of Java by running the version command again:

$ java -version

Step 2 – Download and Extract Solr

Download the latest version of Apache Solr from the official website https://lucene.apache.org/solr/downloads.html.

Once downloaded, extract the archive into a directory, let us say /usr/local/solr.

$ tar -zxvf solr-{version}.tgz -C /usr/local/solr --strip-components=1

Step 3 – Create Solr User

For the security of your system, it is recommended to run Solr as a dedicated user.

Create a new user solr by running the following command:

$ doas useradd -r -s /sbin/nologin solr

Step 4 – Change Ownership

Change the ownership of the extracted Solr directory to solr user by running the following command:

$ doas chown -R solr:solr /usr/local/solr

Step 5 – Start Solr

Solr can be started as a background process.

Change the directory to the bin folder and start Solr with the following command:

$ cd /usr/local/solr/bin
$ doas -u solr ./solr start

This will start the Solr service as a daemon process.

Step 6 – Access Solr

After starting Solr, you can access the Solr admin dashboard by navigating to http://localhost:8983/solr with your web browser.

You have successfully installed Apache Solr on OpenBSD.

Step 7 – Stop Solr

Whenever needed, Solr can be stopped by running the following command:

$ doas -u solr ./solr stop -all

This will gracefully shut down the Solr service.

Conclusion

In this tutorial, we walked through the process of installing Apache Solr on OpenBSD. With Solr, you can easily search, index, and analyze huge amounts of data.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
