Ubuntu Upstart Job

Firstly ensure Deluge daemon and Web UI are installed:

sudo apt-get install deluged deluge-web

User Management

It is best to run Deluge upstart scripts with a specific user and group. You can create one using the following command:

sudo adduser --system --group --home /var/lib/deluge deluge

• This creates a new system user and group named deluge with no login access and home directory: /var/lib/deluge

Add any users you wish to be able to easily manage or access files downloaded through Deluge to the group deluge will run as, for example:

sudo adduser <username> deluge

Deluge Daemon (deluged) Job

Create the file /etc/init/deluged.conf with the following code and set uid and gid to the user and group you wish to run deluged as:

Note: 11.04 Natty users replace static-network-up with stopped networking

# deluged - Deluge daemon
#
# The daemon component of Deluge BitTorrent client. Deluge UI clients
# connect to this daemon via DelugeRPC protocol.

description "Deluge daemon"

start on filesystem and static-network-up
stop on runlevel [016]

respawn
respawn limit 5 30

env uid=deluge
env gid=deluge
env umask=007

exec start-stop-daemon -S -c $uid:$gid -k $umask -x /usr/bin/deluged -- -d

• You may wish to modify the above umask as it applies to any files downloaded by deluged.
  • 007 grants full access to the user and members of the group deluged is running as (in this case deluge) and prevents access from all other accounts.
  • 022 grants full access to the user deluged is running as and only read access to other accounts.
  • 000 grants full access to all accounts.

Refer to ​Wikipedia for details of possible values and their effects. Deluged must be stopped and started instead of just restarted after changes. If you enable logging, as described later in this page, the umasks specified here also affect the permissions of newly created logs.

Deluge Web UI (deluge-web) Job

Create the file /etc/init/deluge-web.conf with the following code and set uid and gid as required:

# deluge-web - Deluge Web UI
#
# The Web UI component of Deluge BitTorrent client, connects to deluged and
# provides a web application interface for users. Default url: http://localhost:8112

description "Deluge Web UI"
author "Deluge Team"

start on started deluged
stop on stopping deluged

respawn
respawn limit 5 30

env uid=deluge
env gid=deluge
env umask=027

exec start-stop-daemon -S -c $uid:$gid -k $umask -x /usr/bin/deluge-web

umask 027 grants full access to uid, read access to gid and prevents access from all other accounts. This should only affect the permissions of plugins installed through the Web UI and, if enabled, logs. Group permissions are restricted to read-only to prevent compromised member accounts injecting malicious code into plugins or modifying the logs.

Migration from init.d script

If you followed the old guide to create an init script you need to remove them:

sudo /etc/init.d/deluge-daemon stop
sudo rm /etc/init.d/deluge-daemon
sudo update-rc.d deluge-daemon remove

Starting (and stopping) Upstart Scripts

Deluge Daemon

sudo start deluged

sudo stop deluged

Web UI

Although the Web UI will start/stop automatically when deluged starts/stops it can be manually controlled with:

sudo start deluge-web

sudo stop deluge-web

Note: To prevent the web UI starting automatically comment out (# prefix) the 'start on' line in deluge-web.conf.

Logging

Create a structure for Deluge to log to and give the user that Deluge is running as (in this case deluge) full access to that directory:

sudo mkdir -p /var/log/deluge
sudo chown -R deluge:deluge /var/log/deluge
sudo chmod -R 750 /var/log/deluge

• Note: The above commands affect the log directory and all files within it, combined with the umask specified in the upstart jobs these affect the permissions new logs are created with.
  • 750 grants full access to the deluge user, only recurse tree and read access to members of the deluge group and prevents access from all other accounts. ​Chmod

Edit the upstart job confs like so:

exec start-stop-daemon -S -c $uid:$gid -k $umask -x /usr/bin/deluged -- -d -l /var/log/deluge/daemon.log -L warning

exec start-stop-daemon -S -c $uid:$gid -k $umask -x /usr/bin/deluge-web -- -l /var/log/deluge/web.log -L warning

• Refer to the FAQ for possible log-levels.

Restart the daemon:

sudo restart deluged

Create /etc/logrotate.d/deluge with the following code to rotate the logs:

/var/log/deluge/*.log {
        rotate 4
        weekly
        missingok
        notifempty
        compress
        delaycompress
        sharedscripts
        postrotate
                initctl restart deluged >/dev/null 2>&1 || true
                initctl restart deluge-web >/dev/null 2>&1 || true
        endscript
}
