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

[Brian Andrus]

Steve,


I suspect you did not install the packages.


You need to install slurm-slurmctld to get the slurmctld systemd files:

    /# rpm -qlp slurm-slurmctld-20.11.9-1.el7.x86_64.rpm//
    ///run/slurm/slurmctld.pid//
    /*//usr/lib/systemd/system/slurmctld.service/*/
    ///usr/sbin/slurmctld//
    ///usr/share/man/man8/slurmctld.8.gz//
    /


The same for slurm-slurmdbd. Both of those are management daemons and 
should only be running on one (two if you configure failover) systems.

Your compute nodes need slurm-slurmd, which will provide the systemd 
files for slurmd.
