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 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 for profile %I
After=network.target postgresql.service rabbitmq-server.service

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

ExecStop={{ venv_dir }}/bin/verdi -p %i daemon stop
ExecReload={{ venv_dir }}/bin/verdi -p %i daemon restart

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

[Install]
WantedBy=multi-user.target

Install the service like so:

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

Start the AiiDA daemon service for a profile profile:

sudo systemctl start aiida-daemon@profile.service

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

sudo systemctl disable aiida-daemon@profile.service
