# INSTALLATION OF RVI (DEBIAN) #

This document describes the installation process for the RVI project 
on a Debian 8 ("jessie") Linux machine. Packages are also available 
for [Ubuntu](INSTALL_ubuntu.md) and [Raspbian](INSTALL_raspbian.md). 
See ```BUILD.md``` for building from source.

Please see ```README.md``` for a general description of the project
and its structure.

Please see ```CONFIGURE.md``` for details on configuring and launching
the system once it has been built.

The first milestone of the RVI project is the HVAC demo. Please see
```hvac_demo/README.md``` for details on how to setup, launch and
drive the demo.

# READER ASSUMPTIONS #
In order to build the system, the reader is assumed to be able to:

1. Have a basic understanding of Linux system operations.
2. Install packages on the system.

Please note that the configuration process described in
```CONFIGURE.md``` may have additional skill requirements.

# PREREQUISITES #

1. The Debian 8 system has the latest updates installed.
2. The user can gain root access to install packages.
3. There is at least 5GB of space availabled for packages and code.

----

# INSTALLATION PROCESS #

## INSTALL DEPENDENCIES ##

Install dependent libraries via ```apt-get``` - note you must be root:

    apt-get install python-jsonrpclib

## INSTALL ESL-ERLANG ##

Install `esl-erlang` 18.2, or a later version 18 release:

Tested packages of the latest versions of Erlang can be downloaded from 
[packages.erlang-solutions.com](https://www.erlang-solutions.com/resources/download.html)

Add the following line to your /etc/apt/sources.list

    deb http://packages.erlang-solutions.com/debian jessie contrib

Update and install `esl-erlang`:

    apt-get update
    apt-get install esl-erlang

**If you receive an authentication error** (such as NO_PUBKEY): note 
the hexadecimal value (e.g., 6D975C4791E7EE5E) and request the key:

    apt-key adv --keyserver keyserver.ubuntu.com --recv-keys HEX

where HEX is the hexadecimal value specified in the error. 
Then rerun the ```update``` and ```install``` commands.

## DOWNLOAD AND INSTALL RVI ##

Download the RVI package from https://github.com/PDXostc/rvi_core/releases.

Then install RVI via dpkg:

    sudo dpkg -i rvi_0.5.0-1_amd64.deb

----

## TEST THE RVI SYSTEM ##

To confirm that RVI has started, use `systemctl` as root user:

    systemctl status rvi

Expected output:
