systemd Scripts

Firstly ensure Deluge daemon deluged and Web UI deluge-web are installed.

User Management

For security it is best to run a service with a specific user and group. You can create one using the following command:

sudo adduser --system  --gecos "Deluge Service" --disabled-password --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 to the deluge group any users you wish to be able to easily manage or access files downloaded through Deluge, for example:

sudo adduser <username> deluge

Migration from init.d or upstart script

Get rid of any old init files named deluge in /etc/init.d/ like this:

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

Remove old upstart scripts like this:

sudo stop deluged
sudo stop deluge-web
sudo rm /etc/init/deluge-web.conf
sudo rm /etc/init/deluged.conf

Deluge Daemon (deluged) Service

Create the file /etc/systemd/system/deluged.service:

[Unit]
Description=Deluge Bittorrent Client Daemon 
After=network.target

[Service]
User=deluge
Type=simple
ExecStart=/usr/bin/deluged -d

[Install]
WantedBy=multi-user.target

Now start the service and verify it is running:

systemctl start deluged
systemctl status deluged

Deluge Web UI (deluge-web) Service

Create the file /etc/systemd/system/deluge-web.service:

[Unit]
Description=Deluge Bittorrent Client Web Interface
After=network.target

[Service]
User=deluge
Type=simple
ExecStart=/usr/bin/deluge-web

[Install]
WantedBy=multi-user.target

Now start the service and verify it is running:

systemctl start deluge-web
systemctl status deluge-web

Note: Both these service scripts should be updated so that deluge-web starts on deluged service and both respawn, the same as upstart scripts.

Enable the service on boot

Enable the services to start up on boot:

systemctl enable deluged
systemctl enable deluge-web

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 service files like so:

ExecStart=/usr/bin/deluged -d -l /var/log/deluge/daemon.log -L warning

ExecStart=/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
}
