I'm trying to set up my first slurm installation following these instructions:
https://github.com/nateGeorge/slurm_gpu_ubuntu I've had to deviate a little bit because I'm using virtual machines that don't have GPUs, so I don't have a gres.conf file and in /etc/slurm/slurm.conf I don't have an entry like Gres=gpu:2 on the last line. On my controller vm I get errors when trying to do simple commnands: $ sinfo slurm_load_partitions: Unable to contact slurm controller (connect failure) $ sudo sacctmgr add cluster compute-cluster sacctmgr: error: slurm_persist_conn_open_without_init: failed to open persistent connection to localhost:6819: Connection refused sacctmgr: error: slurmdbd: Sending PersistInit msg: Connection refused sacctmgr: error: Problem talking to the database: Connection refused Something is supposed to be running on port 6819, but netstat shows nothing using that port. What is supposed to be running on 6819? My database (Maria) is running. I can connect to it with `sudo mysql -U root`. When I boot my controller which services are supposed to be running and on which ports? Thanks.
