Solar is based on Java, so we need to install OpenJDK

apt install -y openjdk-11-jdk-headless

Edit .bashrc file

vi ~/.bashrc

Add

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export PATH=$PATH:/usr/lib/jvm/java-11-openjdk-amd64/bin

Log off and log in. Alternatively, you can run

source ~/.bashrc

Next download Apache Solr binary package and install

cd /usr/local/src
wget "https://www.apache.org/dyn/closer.lua/lucene/solr/8.11.1/solr-8.11.1.tgz?action=download"
mv 'solr-8.11.1.tgz?action=download' solr-8.11.1.tgz
tar xzf solr-8.11.1.tgz solr-8.11.1/bin/install_solr_service.sh --strip-components=2
bash ./install_solr_service.sh solr-8.11.1.tgz

To start Apache Solr on boot, run

systemctl enable solr

To start Solr, run
