Thanks Ole, there's some good notes in there I'll use.

My original question was more a packaging issue - In this case I don't
mind installing the rest of the slurm binaries, but ideally I'd like
our slurmdbd host to be just that. slurmdbd alone (and as few other
installed applications as possible).


%if %{slurm_with munge}
%package munge
Summary: Slurm authentication and crypto implementation using Munge
Group: System Environment/Base
Requires: slurm munge
BuildRequires: munge-devel munge-libs
Obsoletes: slurm-auth-munge
%description munge
Slurm authentication and crypto implementation using Munge. Used to
authenticate user originating an RPC, digitally sign and/or encrypt messages
%endif

> Requires: slurm munge
seems to be the culprit

I have a Wiki page describing how to install Munge and Slurm on CentOS 
7: https://wiki.fysik.dtu.dk/niflheim/SLURM

I hope this may help.

Hi folks,

I've just built 16.05.5 into rpms (using the rpmbuild -ta
slurm*.tar.bz2 method) to update a CentOS 7 slurmdbd host.

According to http://slurm.schedmd.com/accounting.html

"Note that SlurmDBD relies upon existing Slurm plugins for
authentication and Slurm sql for database use, but the other Slurm
commands and daemons are not required on the host where SlurmDBD is
installed. Install the slurmdbd, slurm-plugins, and slurm-sql RPMs on
the computer when SlurmDBD is to execute. If you want munge
authentication, which is highly recommended, you will also need to
install the slurm-munge RPM."

so just installing  slurmdbd, slurm-plugins, and slurm-sql works (yum
localinstall), but as expected fails to start:

[2016-10-13T20:19:46.931] error: Couldn't find the specified plugin
name for auth/munge looking at all files
[2016-10-13T20:19:46.931] error: cannot find auth plugin for auth/munge
[2016-10-13T20:19:46.931] error: cannot create auth context for auth/munge
[2016-10-13T20:19:46.931] fatal: Unable to initialize auth/munge
authentication plugin

however it's not possible to cleanly install slurm-munge without slurm:

Is this ok [y/d/N]: y


So - is this just a broken spec file that sets unneeded dependencies
or are the docs wrong that you don't need to install slurm?
