Course idea
A Linux administrator keeps systems available, secure, and repeatable. Everything is a file, and everything can be scripted.
This course takes learners from the first server login through users, storage, networking, security, services, troubleshooting, backups, and automation.
Learning path
Install
→ Configure
→ Secure
→ Automate
→ Monitor
Compare Debian-family systems such as Ubuntu and Debian with the RHEL family including Rocky, AlmaLinux, and RHEL, and understand where apt and dnf fit in cloud operations.
Course modules
Build the practical skills behind reliable Linux operations.
Storage and Networking
Keep data safe and reachable
- Disks, partitions, LVM, ext4, XFS, and /etc/fstab
- IP addressing, DNS, routing, ip, and ss
- SSH and firewalls with ufw and firewalld
- Web servers and services with Nginx basics
Security and Automation
Harden and repeat
- SSH keys, fail2ban, SELinux, and AppArmor basics
- Bash scripting, cron, and systemd timers
- Backups with rsync and tar
- Logs and performance tuning with top, vmstat, and iostat
Debian family
Ubuntu and Debian use apt and are great choices for cloud environments and learners beginning Linux administration.
RHEL family
Rocky, AlmaLinux, and RHEL use dnf and are common in enterprise environments.
Practical habits
Five habits of a good administrator
Least privilege - Back up before changing - Read the logs first - Automate repeat tasks - Document everything.
