If you want to download torrents to Raspberry Pi, it's possible. There are a few options to do so, but the most lightweight option is rTorrent with ruTorrent. I prefer using WebGUI to manage torrents from anywhere (thanks to DDNS).

If you are planning to buy a new Raspberry Pi, I recommend the Raspberry Pi 4B with 2GB RAM, I am perfectly satisfied with it.

This article will show you how to install and configure rTorrent, ruTorrent, and Apache on Raspberry Pi.

Note: I don't recommend installing them with a script from the Internet, I tried it once. Long story short: I had to reinstall my Raspbian.

Note2: Do not download to an SD card, it'll ruin it quickly. Buy one HDD and connect it instead.

In this article we will install these packages (and dependencies):

rTorrent - torrent service
ruTorrent - WebGUI to manage torrents
Apache - web service to serve ruTorrent

Let's get started!

Note: feel free to change the path or username in these commands, but be careful and change them in every relevant command! I used /mnt/Torrent path where I want to download the content of torrents to, the username is "rtorrent", and /var/www/rutorrent/ path where all ruTorrent files are stored.

Open SSH connection to your Raspberry Pi

Update all packages
sudo apt update

Create "rtorrent" user, it will run rtorrent service
sudo adduser --disabled-login --disabled-password --home /mnt/Torrent --system rtorrent

Install all required packages
sudo apt -y install php php7.3-cli php7.3-json php7.3-curl php7.3-cgi php7.3-mbstring libapache2-mod-php libapache2-mod-scgi libapache2-mod-xsendfile apache2 libav-tools ffmpeg mediainfo curl screen sqlite3 git net-tools sox rtorrent libtorrent20 libxmlrpc-core-c3 git

Create and set correct permission for "session" folder
sudo mkdir -p /mnt/Torrent/session
sudo chmod 777 -R /mnt/Torrent/session
sudo chown rtorrent:rtorrent -R /mnt/Torrent/session

Create a new file called "rtorrent.rc", this is the configuration file of rTorrent
sudo nano /mnt/Torrent/.rtorrent.rc

network.scgi.open_port = "127.0.0.1:5000"
throttle.min_peers.normal.set = 10

network.max_open_files.set = 600
network.max_open_sockets.set = 300
method.set_key = event.download.erased,delete_erased,"execute=rm,-rf,--,$d.base_path="

Set correct permission for ".rtorrent.rc"
sudo chmod 777 /mnt/Torrent/.rtorrent.rc

Create folder for ruTorrent
sudo mkdir -p /var/www/rutorrent/

Download ruTorrent from GitHub

WantedBy=multi-user.target

Start and enable rTorrent service
systemctl start rtorrent
systemctl enable rtorrent.service

Check the WebGUI
Check IP address of Raspberry Pi:
hostname -I

Replace the IP and try to open in the browser like this:
192.168.0.102/rutorrent

Note: if you have changed the default path in step 14, do not forget to replace it as well as in here.

It should work Login info provided by you in the step 12.

If it doesn't work for some reason, check the Apache and rTorrent services.
systemctl status apache2 rtorrent

Let's continue with optimization steps

Secure Apache by adding the below lines at the end of apache2.conf file
nano /etc/apache2/apache2.conf

ServerSignature Off
ServerTokens Prod
<IfModule mod_headers.c>
Header unset ETag
</IfModule>
FileETag None

Remove the "index.php" file and create an empty "index.html" instead
rm /var/www/html/index.php
echo “” > /var/www/html/index.html
chmod 444 /var/www/html/index.html

Disable useless logging (extend MicroSD lifetime)
a2disconf other-vhosts-access-log
systemctl reload apache2

Disable unnecessary Apache modules (save memory)
a2dismod proxy_http
a2dismod proxy
a2dismod status
systemctl restart apache2

That's all. Have fun!

Optional: Install RPI-Monitor to check Memory and HDD usage from the web browser.

If it doesn't work for some reason, check the Apache and rTorrent services.
systemctl status apache2 rtorrent
