Daemon as system service
------------------------
If you would like the AiiDA daemon to run at startup of your linux system,
you can set up a
`systemd service <https://www.freedesktop.org/software/systemd/man/systemd.service.html>`_
for it.

Create a file ``aiida-daemon.service`` using the template below, replacing
``{{ venv_dir }}``, ``{{ home_dir }}`` and ``{{ user }}`` by appropriate
values::

[Unit]
Description=AiiDA daemon service
After=network.target

[Service]
Type=forking
ExecStart={{ venv_dir }}/bin/verdi daemon start
PIDFile={{ home_dir }}/.aiida/daemon/log/celery.pid
# 2s delay to prevent read error on PID file
ExecStartPost=/bin/sleep 2

ExecStop={{ venv_dir }}/bin/verdi daemon stop
ExecReload={{ venv_dir }}/bin/verdi daemon restart

User={{ user }}
Group={{ user }}
Restart=on-failure
RestartSec=60 # Restart daemon after 1 min if crashes
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=aiida-daemon

[Install]
WantedBy=multi-user.target

Enable the service like so::

sudo cp aiida-daemon.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl start aiida-daemon.service

After this, the AiiDA daemon should start together with your system.
To remove the service again::

sudo systemctl disable aiida-daemon.service
