The following tutorial describes how to install Apache Solr in Ubuntu in a few simple steps 22.04.
We will do everything through the terminal in a few minutes.

First, we install Java.

We run a terminal and issue the command:

apt-get install default-jdk -y

we check the java version by issuing the command:

java -version

openjdk version "11.0.15" 2022-04-19
OpenJDK Runtime Environment (build 11.0.15+10-Ubuntu-0ubuntu0.22.04.1)
OpenJDK 64-Bit Server VM (build 11.0.15+10-Ubuntu-0ubuntu0.22.04.1, mixed mode, sharing)

We download Apache Solr and unpack it:

wget https://downloads.apache.org/lucene/solr/8.11.1/solr-8.11.1.tgz

tar -xvzf solr-8.11.1.tgz

we run the installation script:

./solr-8.11.1/bin/install_solr_service.sh solr-8.11.1.tgz

If everything went ok, we should see the messages:

Service solr installed.
Customize Solr startup configuration in /etc/default/solr.in.sh

we run Solr on the system with the command:

systemctl start solr

We create the Solr collection:

its - solr -c "/opt/solr/bin/solr create -c newcollection -n data_driven_schema_configs"
