This document is designed to explain how to install LibreSonic as a Tomcat module, on a computer running Linux. As the project expands, this guide will also expand to include other operating systems.
## Installing From Pre-Compiled Package
### Prerequisites
In order to install and run Libresonic, you will need:
* A JDK installation. 1.8.x series of OpenJDK or Oracle JDK 8+ should work.
* A running [Tomcat](http://tomcat.apache.org/) server. If you're unfamiliar with Tomcat, there are many [guides](https://www.linode.com/docs/websites/frameworks/apache-tomcat-on-ubuntu-16-04) on it. For debian/ubuntu like distributions, you may need to ensure /etc/default/tomcat8 has the correct JAVA_HOME set.
Daily WAR files are built by Jenkins and available [here](https://jenkins.zifnab.net/job/libresonic/), curtesy of [zifnab06](https://github.com/zifnab06).
Note that this command copies the war file directly to the Tomcat webapps directory, and renames it to `libresonic.war`.
2. Create the libresonic directory and assign ownership to the Tomcat system user (if running tomcat as a service):
mkdir /var/libresonic
chown tomcat8:tomcat8 /var/libresonic/
3. Start Tomcat, or restart it if running as a service, as in the example below using Systemd:
systemctl restart tomcat8.service
Note that it may take ~30 seconds after the service restarts for Tomcat to fully deploy the app. You can monitor /var/log/tomcat8/catalina.out for the following message:
INFO: Deployment of web application archive /var/lib/tomcat8/webapps/libresonic.war has finished in 46,192 ms
4. In your web browser, navigate to `192.0.2.10:8080/libresonic/`, replacing `192.0.2.0` with your server's IP address, or `127.0.0.1` if installing locally.
## Installing From Source
### Prerequisites
In order to build, install, and run Libresonic, you will need:
* A recent version of [Maven](http://maven.apache.org/).
* A JDK installation. 1.8.x series of OpenJDK or Oracle JDK 8+ should work.
* A running [Tomcat](http://tomcat.apache.org/) server. If you're unfamiliar with Tomcat, there are many [guides](https://www.linode.com/docs/websites/frameworks/apache-tomcat-on-ubuntu-16-04) on it.
On a Debian-based system, you can install all these prerequisites at once with:
2. Confirm that the $JAVA_HOME environment variable is set:
echo $JAVA_HOME
3. If Java is installed, but the `JAVA_HOME` variable not set, be sure to [set it](http://www.cyberciti.biz/faq/linux-unix-set-java_home-path-variable/) before you continue.
6. Create the libresonic directory and assign ownership to the Tomcat system user (if running tomcat as a service):
mkdir /var/libresonic
chown tomcat8:tomcat8 /var/libresonic/
7. Start Tomcat, or restart it if running as a service, as in the example below using Systemd:
systemctl restart tomcat8.service
Note that it may take ~30 seconds after the service restarts for Tomcat to fully deploy the app. You can monitor /var/log/tomcat8/catalina.out for the following message:
INFO: Deployment of web application archive /var/lib/tomcat8/webapps/libresonic.war has finished in 46,192 ms
8. In your web browser, navigate to `192.0.2.10:8080/libresonic/`, replacing `192.0.2.0` with your server's IP address, or `127.0.0.1` if installing locally.
