Apache Solr is an open-source search engine platform that is used for indexing and searching data. In this tutorial, we will learn how to install Apache Solr on Alpine Linux.
Before installing Apache Solr, make sure that your system is up-to-date. You can update and upgrade your system by running the following commands:
$ sudo apk update
$ sudo apk upgrade
Apache Solr requires Java to be installed on your system. You can install OpenJDK 8 on Alpine Linux by running the following command:
$ sudo apk add openjdk8
Download the latest version of Apache Solr by visiting its official website (https://lucene.apache.org/solr/downloads.html). Alternatively, you can use the following command to download the latest version of Apache Solr:
$ wget https://archive.apache.org/dist/lucene/solr/8.10.0/solr-8.10.0.tgz
Extract the downloaded file:
$ tar xzf solr-8.10.0.tgz
Create a solr user by running the following command:
$ sudo adduser -D -h /opt/solr -s /sbin/nologin solr
Move the extracted solr files to the solr user directory:
$ sudo mv solr-8.10.0 /opt/solr/
Change ownership of the solr directory to the solr user:
$ sudo chown -R solr:solr /opt/solr/
Copy the default Solr configuration files to the Solr user directory:
$ sudo cp -p /opt/solr/server/solr/solr.xml /opt/solr/server/solr/solr.xml.orig
$ sudo cp -r /opt/solr/server/solr/configsets/_default /opt/solr/server/solr/<collection-name>
Note: Replace <collection-name> with a name of your choice.
Start Solr by running the following command:
$ sudo -u solr /opt/solr/bin/solr start -p 8983
Open your web browser and go to http://localhost:8983/solr. You should see the Solr administration panel.
Congratulations! You have successfully installed Apache Solr on Alpine Linux.
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!
