[slurm-users] slurm_persist_conn_open_without_init: failed to open persistent connection to host

[Sushil Mishra]

Hi all,

I installed slurm and enable accounting in a single-node machine, i.e same
server is the master and computing node. I mainly followed this page for
instructions:
https://southgreenplatform.github.io/trainings/hpc/slurminstallation/
After enabling accounting I am having problems in starting
slurmctld.service.
[root at mannose sushil]# cat /var/log/slurm/slurmctld.log
[2022-11-30T16:32:15.194] Job accounting information stored, but details

It is not clear why slurm port 8619 is being used while I have
SlurmctldPort=6817 and SlurmdPort=6818 set in clurm.conf. anyways, I opened
all three posrts (6817, 6818 and 6819) using  'firewall-cmd --permanent
--zone=public --add-port=6819/tcp'

Can someone help in figuring out possibly what is going wrong?
