rtorrent and rutorrent - multiple instances

This article describes how to run multiple instances of rtorrent and rutorrent. You can change rutorrent1 username to your username in the whole article, and in all commands which you want to have, for another rtorrent/rutorrent instance.

Please login to your service SSH, here is an article how to do this:
https://www.seedhost.eu/whmcs/knowledgebase.php?action=displayarticle&catid=36&id=54

1. Firstly create a new downloads path and other required directories for a new user:
mkdir -p ~/downloads/rutorrent1/watch ~/.config/.rutorrent1/.session
2. Copy rtorrent.rc file for a new user:
cp ~/.rtorrent.rc ~/.rutorrent1.rc
3. Now edit .rutorrent1.rc file:

Find these lines:
directory = ~/downloads
schedule = watch_directory,5,5,load_start=~/downloads/watch/rtorrent/*.torrent
session = /home/server/.config/.session
scgi_port = 127.0.0.1:XXXX
execute = {sh,-c,/usr/bin/php /yourhome/yourusername/www/yourusername.servername.seedhost.eu/yourusername/rutorrent/php/initplugins.php yourusername &}
Change them with sed using the following commands:
sed -i "s:^directory.*:directory = ~/downloads/rutorrent1:" ~/.rutorrent1.rc
sed -i "s:/downloads/watch/rtorrent:/downloads/rutorrent1/watch:" ~/.rutorrent1.rc
sed -i "s:.config/:.config/.rutorrent1/:" ~/.rutorrent1.rc
sed -i "s:scgi_.*:scgi_port = localhost\:$(shuf -i 13000-13500 -n 1):" ~/.rutorrent1.rc
sed -i "s:php $(whoami):php rutorrent1:" ~/.rutorrent1.rc
That's all with rutorrent1.rc file.

4. Now create a rutorrent1 directory under your www path
mkdir -p ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1/
5. Copy rutorrent files to rutorrent1 directory
cp -fr ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent/* ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1/
6. Now remove all your main user settings like: traffic/torrents history, hdd usage etc. from rutorrent1 configuration:
rm -rf ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1/share/users/$(whoami)
7. If you have installed autodl-irssi plugin, you need to remove it as well:
rm -rf ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1/plugins/autodl*
8. You need to edit rutorrent1 config file:
sed -i "s:\$scgi_port.*:\$scgi_port = \"$(grep scgi .rutorrent1.rc | awk -F ':' '{print $2}')\";:" ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1/conf/config.php
sed -i "s:\$XMLRPCMountPoint.*:\$XMLRPCMountPoint = \"$(whoami)/rutorrent1/RPC1\";:" ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1/conf/config.php
sed -i "s:\$topDirectory.*:\$topDirectory = \'$HOME/downloads/rutorrent1\';:" ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1/conf/config.php
sed -i "s:rutorrent/error:rutorrent1/error:" ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1/conf/config.php
9. Configure user rutorrent1 authentication for RPC and rutorrent access.
echo -e "SCGIMount /$(whoami)/rutorrent1/RPC1 127.0.0.1:$(grep scgi .rutorrent1.rc | awk -F ':' '{print $2}')\n\n" > ~/.apache2/conf.d/rutorrent1.conf
echo -e "<Location /$(whoami)/rutorrent1/RPC1>\nAuthName 'rutorrent1'\nAuthType Basic\nAuthBasicProvider file\nAuthUserFile '$HOME/.apache2/rutorrent1_auth'\nRequire valid-user\n</Location>" >> ~/.apache2/conf.d/rutorrent1.conf
echo -e "AuthName 'Private'\nAuthType Basic\nAuthBasicProvider file\nAuthUserFile '$HOME/.apache2/rutorrent1_auth'\nRequire valid-user" > ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1/.htaccess
htpasswd -cb ~/.apache2/rutorrent1'_auth' rutorrent1 password
For a password choose one which you want to have for rutorrent1 user.

10. Restart the apache webserver:
/usr/sbin/apache2ctl -k graceful
11. Start rtorrent in screen:
screen -dm -S rutorrent1 rtorrent -n -o import=~/.rutorrent1.rc
12. Create a cronjob to check every 5 minutes if rtorrent is running for rutorrent1 user, if not this will start it :
(crontab -l ;echo -e "*/5\t*\t*\t*\t*\tps x | grep rutorrent1 | grep -v grep || screen -dm -S rutorrent1 rtorrent -n -o import=~/.rutorrent1.rc && screen -wipe") | crontab -u $(whoami) -
That's all, now you should install the proftpd server from your manager and configure it for a new user so that he will have an access only to his downloads path. Here is an article on how to do this:

https://www.seedhost.eu/whmcs/knowledgebase/226/Customize-proftpd-server.html

Ho to delete user rutorrent1 and all his files:

1. Firstly delete cronjob for user:
crontab -l | sed -e "/rutorrent1/d" | crontab -u $(whoami) -
2. Stop rtorrent of rutorrent1 user:
kill -9 $( pgrep -f rutorrent1)
3. Remove all user files:
rm -rf ~/www/$(whoami).$(hostname)/$(whoami)/rutorrent1
rm -f ~/.apache2/rutorrent1*
rm -f ~/.apache2/conf.d/rutorrent1*
rm -rf ~/downloads/rutorrent1
4. Restart the apache webserver:
/usr/sbin/apache2ctl -k graceful
