DIY Raspberry Pi based Media Box

This was posted on 2023-07-08

This project is focused on building a system for my Raspberry Pi so that it can do the following things.

• Act as a network attached storage for my house
• Automatically download and manage my media
• Handle alerts from my CCTV camera
• Notify my phone on any important events
• Have Web App to monitor and control the system

Setting up the Raspberry Pi

I initially got started with a new Raspbian lite OS and connect through SSH

sudo apt-get update
sudo apt-get upgrade

Mounting USB Drives

Check the drives currently mounted

sudo cat /proc/mounts

  or

sudo fdisk -l

and look for the partition starting with /dev/ that has the expected file size, e.g. /dev/sda/.

sudo mkdir /mnt/MediaBox

sudo mount /dev/sda1 /mnt/MediaBox

Gety UUID to Set up Automatic Mounting

sudo blkid

sudo nano /etc/fstab

Add following line with UUID, mount location and file system type 

UUID=27705CE4072C15B2 /mnt/MediaBox ntfs defaults,auto,users,rw,nofail 0 0

Setting up a location to maintain server files

mkdir server
cd server

mkdir static
mkdir templates

Setting static IP

hostname -I
ip r
grep 'namesever' /etc/resolv.conf

nano /etc/dhcpcd.conf

Then appended the following lines to the end of the file

interface wlan0
static ip_address=192.168.1.30/24
static routers=192.168.1.1
static domain_name_servers=1.1.1.1

interface eth0
static ip_address=192.168.1.32/24
static routers=192.168.1.1
static domain_name_servers=1.1.1.1

sudo reboot

Setting up NAS (Samba server)

sudo apt-get install samba samba-common-bin
sudo nano /etc/samba/smb.conf

[Media]
path = /mnt/MediaBox
writeable=Yes
create mask=0777
directory mask=0777
public=no

[Pi]
path = /home/pi
writeable=Yes
create mask=0777
directory mask=0777
public=no

Creating user account with username 'pi' and password 'raspberry'

sudo smbpasswd -a pi

sudo systemctl restart smbd

Setting up Transmission

sudo apt-get install transmission-daemon

Setting up transmission

sudo systemctl stop transmission-daemon

sudo nano /etc/transmission-daemon/settings.json
