PyMedusa Setup

Medusa is an Automatic Video Library Manager for TV Shows. It watches for new episodes of your favorite shows, and when they are posted it does its magic. It is mainly written in Python and javascript, and is very easy to install :

Intitial Setup

We're going to install Medusa on a debian10 CT on proxmox:

Then start the CT and ssh into it:

[ 10.0.0.10/16 ] [ /dev/pts/19 ] [Github/blog/servers]
→ ssh root@10.0.0.173
The authenticity of host '10.0.0.173 (10.0.0.173)' can't be established.
ED25519 key fingerprint is SHA256:inPSVYTAXYA1JprBpkjIowAOmlo1EH5Wvpakh+K3cEI.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '10.0.0.173' (ED25519) to the list of known hosts.

Then install the required dependencies:

root@medusa:~# apt update -y ; apt upgrade -y ; apt install vim -y

root@medusa:~# apt install git-core openssl mediainfo -y

once that's done, create the medusa user:

root@medusa:~# addgroup --system medusa
Adding group `medusa' (GID 115) ...
Done.

root@medusa:~# adduser --disabled-password --system --home /var/lib/medusa --gecos "Medusa" --ingroup medusa medusa
Adding system user `medusa' (UID 107) ...
Adding new user `medusa' (UID 107) with group `medusa' ...
Creating home directory `/var/lib/medusa' ...

root@medusa:~#
	

root@medusa:~# mkdir /opt/medusa ; chown medusa:medusa /opt/medusa

root@medusa:~# mkdir /opt/medusa/media/
root@medusa:~# chown -R medusa:medusa /opt/medusa
	

Once that's done, create the systemd service file to launch medusa:

root@medusa:~# cp -v /opt/medusa/runscripts/init.systemd /etc/systemd/system/medusa.service
'/opt/medusa/runscripts/init.systemd' -> '/etc/systemd/system/medusa.service'

root@medusa:~# chown root:root /etc/systemd/system/medusa.service

root@medusa:~# chmod 644 /etc/systemd/system/medusa.service

root@medusa:~# systemctl enable --now medusa

Once that's done, the service is started, and we can view our medusa instance on port 8081:

Once you've selected the show to add, select where to store the files (i chose the /opt/medusa/media/) folder because i know the medusa user can access it.

next we're going to leave the options as default except for the quality set to 'Any':

Now by default medusa comes with no providers enabled, so let's go and select at least 2 of them:

Once selected, hit 'Save' at the bottom of the page, and return to your shows page:

Select a season, and change it's status to 'Wanted':

So here you can see that it managed to 'Snatch' the episodes we selected:

Now from here medusa's job is done, it basically downloaded the .torrent files, but it still needs to send them somewhere:

Now we know the .torrent files will be located at /opt/medusa/media:

Here you can see what medusa is doing, it is saving the .torrent files in the /opt/medusa/media/ folder as it snatches them, not it's basically time to setup rtorrent to automatically recursively download what arrives in that directory.

rtorrent setup

For the torrenting itself, you can use any torrent client you want. Since we're in a ssh connection we're going to use rtorrent:

root@medusa:/opt/medusa# apt search rtorrent
Sorting... Done
Full Text Search... Done

rtorrent/stable 0.9.7-1 amd64
  ncurses BitTorrent client based on LibTorrent from rakshasa
	
root@medusa:/opt/medusa# apt install rtorrent -y

before launching it, edit the ~/.rtorrent.rc file:
