Raspberry PI + RTorrent +Apache2 + RUTorrent

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:
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
make install

With libtorrent installed it’s time to compile and install rtorrent

cd /root/rtorrent/rtorrent-0.9.2
./configure --with-xmlrpc-c
make install

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:-

# This is an example resource file for rTorrent. Copy to
# ~/.rtorrent.rc and enable/modify the options as needed. Remember to
# uncomment the options you wish to enable.

# Maximum and minimum number of peers to connect to per torrent.
#min_peers = 40
#max_peers = 100

# Same as above but for seeding completed torrents (-1 = same as downloading)
#min_peers_seed = 10
#max_peers_seed = 50

# Maximum number of simultanious uploads per torrent.
#max_uploads = 15

# Global upload and download rate in KiB. "0" for unlimited.
download_rate = 0
upload_rate = 100

# Default directory to save the downloaded torrents.
directory = ~/torrents

# Default session directory. Make sure you don't run multiple instance
# of rtorrent using the same session directory. Perhaps using a
# relative path?
session = ~/.sessions

# Watch a directory for new torrents, and stop those that have been
# deleted.
schedule = watch_directory,5,5,load_start=~/watch/*.torrent
schedule = untied_directory,5,5,stop_untied=~/watch/*.torrent

# Close torrents when diskspace is low.
schedule = low_diskspace,5,10,close_low_diskspace=200M

# Stop torrents when reaching upload ratio in percent,

#schedule = ratio,60,60,"stop_on_ratio=200,200M,2000"
#schedule = ratio,5,5,"stop_on_ratio=1,1M,10"
system.method.set = group.seeding.ratio.command, d.close=, d.stop=

# Set Schedules
#schedule = throttle_1,00:10:00,24:00:00,download_rate=0
#schedule = throttle_2,07:50:00,24:00:00,download_rate=200

# Stop Seeding When complete
#system.method.set_key = event.download.finished,1close_seeding,d.close=
#system.method.set_key = event.download.finished,2stop_seeding,d.stop=

#ip =
#ip = rakshasa.no

# The ip address the listening socket and outgoing connections is

port_range = 51515-51520

# Start opening ports at a random position within the port range.
#port_random = no

# Check hash for finished torrents. Might be usefull until the bug is
# fixed that causes lack of diskspace not to be properly reported.
#check_hash = no

# Set whetever the client should try to connect to UDP trackers.
use_udp_trackers = yes

# Alternative calls to bind and ip that should handle dynamic ip's.
#schedule = ip_tick,0,1800,ip=rakshasa
#schedule = bind_tick,0,1800,bind=rakshasa

# Encryption options, set to none (default) or any combination of the following:
# allow_incoming, try_outgoing, require, require_RC4, enable_retry, prefer_plaintext
# The example value allows incoming encrypted connections, starts unencrypted
# outgoing connections but retries with encryption if they fail, preferring
# plaintext to RC4 encryption after the encrypted handshake
# encryption = allow_incoming,enable_retry,prefer_plaintext
#encryption = allow_incomming,try_outgoing

# Enable DHT support for trackerless torrents or when all trackers are down.
# May be set to "disable" (completely disable DHT), "off" (do not start DHT),
# "auto" (start and stop DHT as needed), or "on" (start DHT immediately).
# The default is "off". For DHT to work, a session directory must be defined.
# dht = auto
dht = off

# UDP port to use for DHT.
# dht_port = 6881

# Enable peer exchange (for torrents not marked private)
# peer_exchange = yes
peer_exchange = no

# Do not modify the following parameters unless you know what you're doing.

# Hash read-ahead controls how many MB to request the kernel to read
# ahead. If the value is too low the disk may not be fully utilized,
# while if too high the kernel might not be able to keep the read
# pages in memory thus end up trashing.
#hash_read_ahead = 10

# Interval between attempts to check the hash, in milliseconds.
#hash_interval = 100

# Number of attempts to check the hash while using the mincore status,
# before forcing. Overworked systems might need lower values to get a
# decent hash checking rate.
#hash_max_tries = 10

#Added for rutorrent stuff
encoding_list = UTF-8
#scgi_local = /tmp/rpc.socket
#schedule = chmod,0,0,"execute=chmod,777,/tmp/rpc.socket"
scgi_port = localhost:5000

# Start The Plugins when Rtorrent Starts not when the page is first opened. If apache service is restart separately the plugins are likely to be stopped. Only really needed for RSS feeds.
execute = {sh,-c,/usr/bin/php /var/www/php/initplugins.php &}

Save and Exit (ctrl+x then y then enter)
We now need to perform a test run of 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.


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:-


# To start the script automatically at bootup type the following command
# update-rc.d torrent defaults 99


case $1 in
#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"
echo "The process failed to start"

#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"
echo "The process failed to stop"

# show the options
echo "Usage: {start|stop}"

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.
