Put mp3 stream into the air, Raspberry Pi

In this tutorial i set up Raspberry Pi to put mp3 stream into the air.
This means that i am creating my very own internet radio.

This solution uses:
mpd which stands for Music Player Daemon,
mpc which stands for Music Player Controller,
icecast2 which put thing together and serve the stream via port 8000

Here is how i implemented it:

#!/bin/sh
#this is tested on fresh 2016-03-18-raspbian-jessie-lite.img

#move to supper user
#sudo su

#move to home directory
#cd

#clone repo
#git clone https://github.com/catonrug/raspbian-icecast2-mpd-mpc.git
#cd raspbian-icecast2-mpd-mpc
#chmod +x install.sh
#./install.sh

#update the system
apt-get update -y && apt-get upgrade -y

#set up correct time zone
cp /usr/share/zoneinfo/Etc/GMT-2 /etc/localtime

#install music player daemon
apt-get install mpd -y

#put IP address into the variable
ipaddress=$(ifconfig | grep "inet.*cast" | sed "s/[: ]/\n/g" | grep -m1 "[0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+")

#set mpd configuration file. you can change 'hackme' password.
#make sure you type the same password as in icecast configuration

To use this code with git use:

sudo su
cd
git clone https://github.com/catonrug/raspbian-icecast2-mpd-mpc.git
cd raspbian-icecast2-mpd-mpc
chmod +x install.sh
./install.sh
