Local Installation

Prerequisites

If you are using a VM make sure it has at least 8 GB of RAM (It may work with 4 GB, but with 2 GB it
does give issues).

Create MUSIC Install dir /opt/app/music

Ensure you have OpenJDK 8 on your machine.

Ensure you have maven installed on your machine, and configured for ONAP. To build you will need to ensure you update your settings with the ONAP settings.xml (Workspace and Development Tools)

NOTE: If you are having trouble with some of the apt-get installation packages, enter the name of the vm alongside localhost in the line for 127.0.0.1 in /etc/hosts. Some of the apt-get installation may require this.
