Asked a question recently

How do I call Slurm utilities from nodes that run no slurmdbd?

Where am I?

In Bright Computing, Inc. you can ask and answer questions and share your experience with others!

On a node, some Slurm utilities such as sacct need to connect to the slurmdbd daemon.  slurmdbd in turn talks to mysql. If the node is not running slurmdbd, then the node can be assigned to connect to slurmdbd by changing the line:

AccountingStorageHost=<DBHOST>

in /etc/slurm/slurm.conf.

Here, <DBHOST> is the hostname of a node where an appropriate slurmdbd daemon is running.
