How To Install Apache Solr 9.0 on Ubuntu 18.04

    RahulBy 2 Mins ReadUpdated:

    Apache Solr is an open-source search platform written on Java. Solr provides full-text search, spell suggestions, custom document ordering and ranking, Snippet generation, and highlighting. This tutorial will help you to install Apache Solr 8.9 on Ubuntu 18.04, 16.04, and 14.04 systems.

    Step 1 – Install Java

    Apache Solr 7 required Java 8 or greater to run. Make sure your system fulfills the Java requirements of Apache Solr. If you don’t have java installed on your system visit the below articles.

    sudo apt install openjdk-11-jdk

    Verify active Java version:

    java -version

openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3)
OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3, mixed mode, sharing)

    You can also follow this tutorial to install Java on Ubuntu Linux.

    Step 2 – Install Apache Solr on Ubuntu

    Now download the required Solr version from its official site or mirrors. Or simply use the following command to download Apache Solr 9.0.

    wget https://dlcdn.apache.org/solr/solr/9.0.0/solr-9.0.0.tgz

    Now extract the Apache Solr service installer shell script from the downloaded Solr archive file and run the installer using the following commands.

    tar xzf solr-9.0.0.tgz solr-9.0.0/bin/install_solr_service.sh --strip-components=2
sudo bash ./install_solr_service.sh solr-9.0.0.tgz

    Step 3 – Start / Stop Solr Service

    Solr is configured as a service on your system. You can simply use the following commands to Start, Stop and check the status of the Solr service.

    sudo service solr stop
sudo service solr start
sudo service solr status

    Step 4 – Create First Solr Collection

    After the successful installation of Solr on your system. Create the first collection in Apache Solr using the following command.

    sudo su - solr -c "/opt/solr/bin/solr create -c mycol1 -n data_driven_schema_configs"

    Sample output:

    Created new core 'mycol1'

    Step 5 – Access Solr Admin Panel

    Default Solr runs on port 8983. You can access the Solr port in your web browser using the server IP or domain name pointed to that server and you will get the Solr dashboard.

      http://demo.tecadmin.net:8983/

    Install Solr on Ubuntu

    Now, select “MyCol1” under core selector drop down in left sidebar

    Install Apache Solr on Ubuntu

    Here you can view statics of created collection in previous steps named “mycol1”. Click on “Core Selector” on the left sidebar and select created collection.

    Share.

      I followed this guide and it worked. However, it didn’t say so directly in the text, but this will install Solr as a service that auto-starts when you (re)boot Ubuntu. I’m just saying, because I had a doubt and actually went and rebooted my Ubuntu server just to test if it would.
