readme.md

1. Install spotify from here:

# 1. Add the Spotify repository signing keys to be able to verify downloaded packages
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 931FF8E79F0876134EDDBDCCA87FF9DF48BF1C90

# 2. Add the Spotify repository
echo deb http://repository.spotify.com stable non-free | sudo tee /etc/apt/sources.list.d/spotify.list

# 3. Update list of available packages
sudo apt-get update

# 4. Install Spotify
sudo apt-get install spotify-client

2. Installing apache2

• sudo apt install apache2
  sudo a2enmod rewrite headers proxy proxy_http proxy_wstunnel 

• Setup the forwarding configuration, copy the shiny_forward.conf from below to /etc/apache2/sites-available, and remove the other 000-default.conf.

3. Installing R (from https://cran.rstudio.com/bin/linux/ubuntu/README.html):

• #For ubuntu 18.10
  sudo bash -c 'echo deb https://cloud.r-project.org/bin/linux/ubuntu cosmic-cran35/ > /etc/apt/sources.list.d/r.list'
  #For ubuntu 18.04
  sudo bash -c 'echo deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/ > /etc/apt/sources.list.d/r.list'
  sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 51716619E084DAB9
  sudo apt update
  sudo apt install r-base

shiny_forward.conf

<VirtualHost *:80>
	# The ServerName directive sets the request scheme, hostname and port that
	# the server uses to identify itself. This is used when creating
	# redirection URLs. In the context of virtual hosts, the ServerName
	# specifies what hostname must appear in the request's Host: header to
	# match this virtual host. For the default virtual host (this file) this
	# value is not decisive as it is used as a last resort host regardless.
	# However, you must set it for any further virtual host explicitly.
	#ServerName www.example.com

	ServerAdmin webmaster@localhost
	DocumentRoot /var/www/html

	# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
	# error, crit, alert, emerg.
	# It is also possible to configure the loglevel for particular
	# modules, e.g.
	#LogLevel info ssl:warn

	ErrorLog ${APACHE_LOG_DIR}/error.log
	CustomLog ${APACHE_LOG_DIR}/access.log combined

	# For most configuration files from conf-available/, which are
	# enabled or disabled at a global level, it is possible to
	# include a line for only one particular virtual host. For example the
	# following line enables the CGI configuration for this host only
	# after it has been globally disabled with "a2disconf".
	#Include conf-available/serve-cgi-bin.conf
