[slurm-users] Slurm Configuration assistance: Unable to use srun after installation (slurm on fedora 33)

[Johnsy K. John]

Hello SchedMD team,

I would like to use your slurm workload manager for learning purposes.
And I tried installing the the software (downloaded from:
https://www.schedmd.com/downloads.php ) and followed the steps as mentioned
in:

https://slurm.schedmd.com/download.html
https://slurm.schedmd.com/quickstart_admin.html


My Linux OS is fedora 33, and i tried installing it as root login.
After installation and configuration as mentioned in page:
https://slurm.schedmd.com/quickstart_admin.html
I got some errors when I tried to do srun.
Details about the installation and use are as follows:

Using root permissions, copied to: /root/installations/

cd /root/installations/

tar --bzip -x -f slurm-20.11.5.tar.bz2

cd slurm-20.11.5/

./configure --enable-debug --prefix=/usr/local --sysconfdir=/usr/local/etc

make
make install


Following steps are based on
https://wiki.fysik.dtu.dk/niflheim/Slurm_configuration

mkdir /var/spool/slurmctld /var/log/slurm
chown johnsy /var/spool/slurmctld
chown johnsy /var/log/slurm
chmod 755 /var/spool/slurmctld /var/log/slurm

 cp /var/run/slurmctld.pid /var/run/slurmd.pid

touch /var/log/slurm/slurmctld.log
chown johnsy /var/log/slurm/slurmctld.log

touch /var/log/slurm/slurm_jobacct.log /var/log/slurm/slurm_jobcomp.log
chown johnsy /var/log/slurm/slurm_jobacct.log
/var/log/slurm/slurm_jobcomp.log

ldconfig -n /usr/lib64


Now when I tried an example command for trial:

srun /proc/cpuinfo


I get the following error:

srun: error: Unable to allocate resources: Unable to contact slurm
controller (connect failure)



My configuration file slurm.conf f that i created is:
