# Startup Configuration Guide

Libresonic has some system-wide configuration. These configurations are stored in the 
`libresonic.properties` file. There are some exceptions, such as the `libresonic.home` parameter, which 
are supplied as a Java System Property.

## libresonic.properties Parameters
These parameters are simple key-value pairs stored in a list. It is recommended that these parameters
are changed through the web interface settings page. However, they can also be modified directly. Shutdown
your server first, modify, then start it for changes to take effect.

## Java Parameters
These parameters are not modifiable through the web interface. See below for steps for setting Java Parameters.

#### `libresonic.home`
This parameter dictates the folder where Libresonic will store its logs, 
settings, transcode binaries, index and database if using the default H2 
database. As such it is recommended to backup this folder.

*default: `/var/libresonic` or `C:\\music`*

### Spring Boot/Standlone Specific Configs
The following configs only apply when running libresonic as a standalone package (i.e. without Tomcat or Jetty). These are only a subset of the connfigurations for spring-boot, the full list can be found [here](https://docs.spring.io/spring-boot/docs/1.4.5.RELEASE/reference/htmlsingle/#common-application-properties). Not that not all configurations apply to libresonic, but the important section is the `# EMBEDDED SERVER CONFIGURATION` section.

#### `server.port`
This property only applies for spring boot/standalone config. It changes the port that the standalone package listens on.

*default: 8080*

#### `server.address`
This property only applies for spring boot/standalone config. It changes the address that the standalone package listens on.

*default: not set and listens to all addresses*

### Setting Java Parameters on Tomcat
As described in the [RUNNING.txt](http://tomcat.apache.org/tomcat-8.0-doc/RUNNING.txt) doc provided by tomcat,
you can create a file named `setenv.sh` or for windows `setenv.bat` in the Tomcat home `bin` folder to  modify  the 
java args.

Here is an example of a `setenv.sh` file (`setenv.bat` has slightly different syntax):
```
export JAVA_OPTS="$JAVA_OPTS -Dlibresonic.home=/home/andrew/.cache/libresonic-test"
```

### Setting Java Parameters for Standalone Package (SpringBoot)
When running the standalone package, add `-Dlibresonic.home=YOUR_PATH_HERE` to the `java` command line right before the 
`-jar` argument. Here is an example for linux (windows users will want to use their OS specific path syntax i.e. 
`C:\\your\path`)

```
java -Dlibresonic.home=/home/andrew/libresonichome -jar libresonic.war
```
