What is Solr?

Apache Solr is a fast open-source java search server. It is based on the Apache Lucene search libraries. It enables you to easily create search engines which searches websites, databases and files. It provides full-text search, highlight the hits and near real time indexing.

As I said above Apache Solr search server is written in Java. So, It uses a servlet container in the backend to run. If you install Apache Solr by default it comes with Jetty as the servlet container that you can uses to run some examples.

In this tutorial I will show how you can install Apache Solr 7.1 on CentOS/RHEL and Fedora

After downloading the Solr 7.1, now extract Apache Solr service installer shell script from the downloaded solr tar file and run the installer using below command.

# tar xzf solr-7.1.0.tgz solr-7.1.0/bin/install_solr_service.sh --strip-components=2
# sudo bash ./install_solr_service.sh solr-7.1.0.tgz

Follow the below command to start and stop the solr service.
