Slurm Installation on Debian

1. Make sure the clocks, users and groups (UIDs and GIDs) are synchronized across the cluster.

2. Install slurm from repositories - apt-get install slurm-llnl o apt-get install slurm-wlm
3. Open the local file in a browser sftp://ip-node/usr/share/doc/slurmctld/slurm-wlm-configurator.html where ip-node is the ip from slurmctld machine, and fill out the form. The slurm.conf file is generated and copy in /etc/slurm.conf
4. Exist two ways for generate munge.key - /usr/sbin/create-munge-key or with dd if=/dev/random bs=1 count=1024 >/etc/munge/munge.key (recommended for the paranoid) and dd if=/dev/urandom bs=1 count=1024 >/etc/munge/munge.key (recommended for the impatient)
5. copy munge.key in the nodes - ssh /etc/munge/munge.key root@nodes:/etc/munge/munge.key
6. Edit file /etc/passwd and modify munge:x:501:501::var/run/munge;/sbin/nologin in each machine
7. Test munge in local machine - munge -n | unmunge
8. Test munge in nodes machine - munge -n | ssh host1 unmunge
