I’ve been using one of my PI’s as a torrent server for some time. Recently I decided to refresh the entire system. This will NOT go into the legalities of downloading anything, I expect everyone to only be using this for downloading raspberry images 🙂
Version Info:
2014-01-07-wheezy-raspbian.img
libtorrent 0.13.2
rtorrent 0.9.2
rutorrent 3.6
I’m going to assume you can SSH to your PI, and recommend you get all the latest updates before you start. I’m also going to be naughty and be running all the commands as root.
sudo su –
Then we’ll get the stuff needed to compile rtorrent and a few things needed for the plugins
apt-get install subversion build-essential automake libtool libcppunit-dev libcurl3-dev libsigc++-2.0-dev libxmlrpc-c-dev unzip unrar-free curl libncurses-dev apache2 php5 php5-cli php5-curl libapache2-mod-scgi mediainfo ffmpeg screen
While your waiting may as well get a coffee. With that all finished we’re going to grab the rtorrent packages.
mkdir /root/rtorrent
cd /root/rtorrent
wget http://libtorrent.rakshasa.no/downloads/libtorrent-0.13.2.tar.gz
wget http://libtorrent.rakshasa.no/downloads/rtorrent-0.9.2.tar.gz
wget http://dl.bintray.com/novik65/generic/rutorrent-3.6.tar.gz
wget http://dl.bintray.com/novik65/generic/plugins-3.6.tar.gz
tar xvf libtorrent-0.13.2.tar.gz
tar xvf rtorrent-0.9.2.tar.gz
tar xvf rutorrent-3.6.tar.gz
tar xvf plugins-3.6.tar.gz
Now that you’ve got everything extracted it’s time to compile and install libtorrent
cd /root/rtorrent/libtorrent-0.13.2
./autogen.sh
./configure
make
make install
With libtorrent installed it’s time to compile and install rtorrent
cd /root/rtorrent/rtorrent-0.9.2
./autogen.sh
./configure --with-xmlrpc-c
make
make install
ldconfig
Once you’ve reached this bit, we’re finished with the hanging around. We’ll now install rutorrent and it’s plugins
cd /root/rtorrent
rm /var/www/index.html
cp -r rutorrent/* /var/www/
cp -r plugins/* /var/www/plugins
chown -R www-data:www-data /var/www
a2enmod scgi
service apache2 restart
We’ll next create a new user account for rtorrent to run as
adduser -m -r rtorrent
Now we switch to the new user account to add the required rtorrent directories and config
su rtorrent
mkdir .sessions
mkdir complete
mkdir torrents
mkdir watch
nano -w .rtorrent.rc
Copy and Paste the following:-

Save and Exit (ctrl+x then y then enter)
We now need to perform a test run of rtorrent.
rtorrent
It should start without any problems. You may get a few warnings inside rtorrent, but it should still be running. To Exit press ctrl+q.
You should now exit the rtorrent user.
exit
Finally we’re going to setup rtorrent to automatically start when the PI is powered up.
nano -w /etc/init.d/rtorrent
Copy and Paste the Following:-
#!/bin/bash
# To start the script automatically at bootup type the following command
# update-rc.d torrent defaults 99
RTUSER=rtorrent
TORRENT=/usr/local/bin/rtorrent
case $1 in
start)
#display to user that what is being started
echo "Starting rtorrent..."
sleep 4
#start the process and record record it's pid
rm /home/rtorrent/.sessions/rtorrent.lock
start-stop-daemon --start --background --pidfile /var/run/rtorrent.pid --make-pidfile --exec /bin/su -- -c "/usr/bin/screen -dmUS torrent $TORRENT" $RTUSER
## start-stop-daemon --start --background --exec /usr/bin/screen -- -dmUS torrent $TORRENT
#output failure or success
#info on how to interact with the torrent
echo "To interact with the torrent client, you will need to reattach the screen session with following command"
echo "screen -r torrent"
if [[ $? -eq 0 ]]; then
echo "The process started successfully"
else
echo "The process failed to start"
fi
;;
stop)
#display that we are stopping the process
echo "Stopping rtorrent"
#stop the process using pid from start()
start-stop-daemon --stop --name rtorrent
#output success or failure
if [[ $? -eq 0 ]]; then
echo "The process stopped successfully"
else
echo "The process failed to stop"
fi
;;
*)
# show the options
echo "Usage: {start|stop}"
;;
esac
Save and Exit (ctrl+x then y then enter)
Then run
chmod +x /etc/init.d/rtorrent
update-rc.d rtorrent defaults
And that’s it. You could now start rtorrent using “/etc/init.d/rtorrent start”, but it’s just as easy to reboot and test that the startup scripts runs. Once you’ve reboot or started rtorrent you can access the webpage at http://{ip-address or name} Notes:-
This setup is meant to run internally, as such there is no security on the apache setup.
Personally I forward ports 51515-51520 on the router onto the PI, this makes a difference in download speed (much quicker) but as it's opening ports it's a security risk so you'll have to decided whether or not to.
I run this setup behind a vpn using ipredator.se, if there's any demand I'll write up another guide on how to configure that and ensure your traffic is locked to only go over the vpn.
