systemd Scripts
Note: Improvements to propagate from Upstart still: deluge-web starting upon deluged starting and filesystems are mounted e.g. local-fs.target and remote-fs.target.
Verify Deluge Installion
Ensure Deluge daemon deluged and Web UI deluge-web are installed.
Use which deluged or which deluge-web to check installation path.
If they are not installed in the usual /usr/bin modify the service file ExecStart? lines to point to the correct location (e.g. /usr/local/bin/deluged).
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 scripts
Remove any old init.d 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 containing the following:
[Unit] Description=Deluge Bittorrent Client Daemon Documentation=man:deluged After=network-online.target [Service] Type=simple User=deluge Group=deluge UMask=007 ExecStart=/usr/bin/deluged -d Restart=on-failure # Time to wait before forcefully stopped. TimeoutStopSec=300 [Install] WantedBy=multi-user.target
- 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.
- 002 grants full access to the user and group 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.
Now enable it to start up on boot, start the service and verify it is running:
sudo systemctl enable /etc/systemd/system/deluged.service sudo systemctl start deluged sudo systemctl status deluged
Deluge Web UI (deluge-web) Service
Create the file /etc/systemd/system/deluge-web.service containing the following:
[Unit] Description=Deluge Bittorrent Client Web Interface Documentation=man:deluge-web After=network-online.target deluged.service Wants=deluged.service [Service] Type=simple User=deluge Group=deluge UMask=027 # This 5 second delay is necessary on some systems # to ensure deluged has been fully started ExecStartPre=/bin/sleep 5 ExecStart=/usr/bin/deluge-web Restart=on-failure [Install] WantedBy=multi-user.target
Now enable it to start up on boot, start the service and verify it is running:
sudo systemctl enable /etc/systemd/system/deluge-web.service sudo systemctl start deluge-web sudo systemctl status deluge-web
Logging
Create a log directory for Deluge and give the service user (e.g. deluge), full access:
sudo mkdir -p /var/log/deluge sudo chown -R deluge:deluge /var/log/deluge sudo chmod -R 750 /var/log/deluge
- The deluge log directory is now configured so that user deluge has full access, group deluge read only and everyone else denied access. The umask specified in the services sets the permission of new log files.
Enable logging in the service files by editing the ExecStart line, appending -l and -L options:
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
- See Deluge Logging for all available log-levels.
Restart the services:
sudo systemctl daemon-reload sudo systemctl restart deluged sudo systemctl restart deluge-web
Log Rotation
To enable log rotation create /etc/logrotate.d/deluge with the following code:
/var/log/deluge/*.log {
rotate 4
weekly
missingok
notifempty
compress
delaycompress
sharedscripts
postrotate
systemctl restart deluged >/dev/null 2>&1 || true
systemctl restart deluge-web >/dev/null 2>&1 || true
endscript
}
Start deluged only if mount exists
Use this if you have a usb disk drive or network drive that may not be immediately available on boot or disconnected at random.
The following additions wait for those mountpoints before starting deluged. If they are unmounted or disconnected then deluged is stopped. When they become available again deluged is started.
Ensure you have added the correct drive details to fstab or equivalent so they are mounted at boot.
List the available drive mounts:
sudo systemctl -t mount
Look for your mount point in the Description column. Mounts are formatted similar to the mount point with - substituted for / in the path. Eg: media-xyz.mount
Modify the [Unit] section of the deluged.service script. Substitute xyz.mount for the mount you want the service to depend on:
[Unit] Description=Deluge Bittorrent Client Daemon # Start after network and specified mounts are available. After=network-online.target xyz.mount Requires=xyz.mount # Stops deluged if mount points disconnect BindsTo=xyz.mount
For multiple mount points add a space between additional entries. Eg: After=network-online.target xyz.mount abc.mount def.mount
Modify the [Install] section to ensure the deluged service is started when the mount point comes back online:
[Install] WantedBy=multi-user.target xyz.mount
Note: WantedBy seems to work on some distros and not others. Possibly different versions of systemd?
