Slurm node daemon error: Unable to open the PID file

I run systemctl start slurmd.service, and the time runs out:

The task for slurmd.service failed because a timeout was exceeded.

The relevant lines to run. systemctl status slurmd.service:

March 23 17:13:42 fedora1 systemd[1]: Starting the Slurm node daemon ...
March 23 17:13:43 fedora1 systemd[1]: slurmd.service: can not open the PID file /var/run/slurm/slurmd.pid (still?) after startup: No>
