System Administrator

Work by hand through what happens in front of a server every day. Install packages, narrow down layer by layer why a name will not resolve, connect with a key and move files, write one fstab line exactly right, handle qcow2 images and rootless containers, bring GPU drivers into an air-gapped network, and finish a backup with a restore rehearsal. At the end you write a Slurm configuration to spec and find the cause in a broken one.

코스

• Package Management — What happens behind one install command.
• Network Troubleshooting — Break a report of "it doesn't work" into layers.
• SSH and File Transfer — Connect with a key, move files safely, dig a tunnel.
• Storage and Mounts — One fstab line saves or kills your boot.
• Virtualisation with QEMU/KVM — A qcow2 backing chain is what makes a golden image.
• Running Rootless Podman — No daemon, no root, still containers.
• Air-Gapped GPU Driver Installation — A transfer procedure you finish in one USB trip.
• Backup and Restore — Without a restore rehearsal it is not a backup.
• HPC and Slurm — How several people share eight GPUs.
• RHEL-Family Administration — dnf, rpm, createrepo — and unit files.
