[slurm-users] How to launch slurm services after installation

[刘 博涵]

Hi all,

I'm a newcomer to cluster computing and have been trying to setup a Slurm cluster myself. Right now I'm stuck at starting up Slurm's systemd services. I checked out the following tutorials:

  1.  Slurm Workload Manager - Quick Start Administrator Guide (schedmd.com)<https://slurm.schedmd.com/quickstart_admin.html>
  2.  https://wiki.fysik.dtu.dk/Niflheim_system/Slurm_installation/
  3.  https://wiki.bkslab.org/index.php/Slurm_Installation_Guide
  4.  Slurm installation (southgreenplatform.github.io)<https://southgreenplatform.github.io/trainings/hpc/slurminstallation/>

All of them state that I should run systemctl enable/start slurmd/slurmdbd/slurmctld after installation, however they always fail because the corresponding systemd config files do not exist, regardless of whether I installed Slurm from source or from EPEL repos. All my systems are CentOS 7.9 with the latest updates prior to Slurm installation, and I was trying to install Slurm 22.05.6 from source. My question is are the systemd config files actually created during installation process as the tutorials imply, or do I have to write them myself? If the latter, then how should I write my slurm systemd config file (what parameters should I put in etc.), any templates I can follow?

Many thanks,

Steve
