Course overview

Linux runs behind almost every server, cloud platform and container in use today. Whether you work with Docker, Kubernetes, AWS or Azure, Linux is the foundation you need. This course is designed for system administrators and anyone moving into infrastructure and DevOps, starting from zero: installation, basic commands, the filesystem hierarchy, permissions and user management, packages, processes and systemd, disks, networking, security and SSH, reading logs, and finally writing shell scripts and

scheduling automated jobs. Every topic is hands-on on real Linux machines (Ubuntu and the RHEL family) using commands that real server work requires, with continuous labs simulating real situations such as setting up a new server, recovering a failed service and checking security posture. Learners take home a command cheat sheet and sample scripts. (3 days, 6 hours per day, 18 hours in total, Beginner to Intermediate level, no Linux background required.)

What you’ll gain

Section 4: User and Group Management

Creating and managing users and groups with useradd, usermod, groupadd and the /etc/passwd and /etc/shadow files
Setting passwords, password policy and locking or disabling accounts
Privilege escalation with sudo and configuring sudoers under least privilege
Lab: create team user accounts with restricted sudo rights

Day 2 Packages, Services, Disks and Networking

Section 5: Package and Software Management

Installing and removing software with APT (Ubuntu/Debian) and DNF (RHEL/Rocky)
Searching packages, updating the system and managing repositories
Installing from source and an introduction to Snap and containers
Lab: install and update the software a server needs

Section 6: Processes and Service Management with systemd

Viewing processes with ps, top and htop and managing them with kill and nice
systemd concepts: units, services, targets and using systemctl (start, stop, enable, status)
Reading failed service status and basic troubleshooting
Lab: install a service, enable it at boot and fix it when it fails to start

Section 7: Disks, Partitions and Filesystems

Inspecting disks with lsblk, df and du and planning storage
Creating partitions, formatting filesystems (ext4, xfs) and mounting temporarily and permanently via /etc/fstab
An introduction to LVM and extending storage
Lab: add a new disk, create a partition and mount it permanently

Section 8: Networking on Linux

Configuring IP, gateway and DNS and verifying with ip, ping, ss, curl and dig
Setting the hostname and working with /etc/hosts and resolv.conf
Opening and closing ports with a firewall (ufw and firewalld) and checking listening ports
Lab: configure networking and the firewall so the server is usable and secure

Day 3 Security, Logs and Automation

Section 9: SSH and Server Security

Securing SSH: key-based login, disabling root login, changing the port and restricting users
Using scp and rsync for copying and backing up data
Basic hardening practices and applying security patches
Lab: set up SSH keys and harden a server against a checklist

Section 10: Logs and System Monitoring

Reading logs with journalctl and the log files under /var/log
Monitoring system resources (CPU, memory, disk, network) and diagnosing a slow machine
Log rotation with logrotate and planning log retention
Lab: analyze a problem from the logs and find the cause of a failed service

Section 11: Shell Scripting and Automation

Bash scripting basics: variables, conditionals, loops and reading input
Writing scripts for routine work such as backups, health checks and alerts
Scheduling automated jobs with cron and systemd timers
Lab: write a backup script and schedule it to run daily

Frequently asked questions

What do rwx permissions and numbers such as 755 mean in Linux?

Linux permissions are split into three classes: the owner (user), the group and everyone else (other). Each class can have read (r), write (w) and execute (x). In octal notation r is 4, w is 2 and x is 1, added together per class, so 755 gives the owner rwx and the group and others r-x. You change permissions with chmod and ownership with chown.

How do you secure SSH on a Linux server?

Start by generating an SSH key pair on your own machine and copying the public key to the server with ssh-copy-id. Then edit /etc/ssh/sshd_config to disable password logins and root login, and limit who can connect with AllowUsers. Restart sshd while keeping your existing session open in case of a mistake, and allow the SSH port only where needed in the firewall. This course practises hardening a server against a checklist.

What is systemd, and how do you manage services with systemctl?

systemd is the first process started at boot and manages services and other components as units. Use systemctl start and stop to run or halt a service, enable to start it automatically at boot, and status to check it. When a service fails, journalctl -u followed by the service name shows its log, which usually reveals the cause, such as a configuration error or a port already in use.

Who is the Linux Administration for System Administrators course for, and what should I know beforehand?

It suits system administrators and IT support staff who look after Linux servers, people moving into infrastructure, DevOps or cloud roles, and developers who deploy to servers or use Docker and Kubernetes. No Linux or programming experience is required, only basic computer and internet skills, although some command-line use on Windows or macOS will help.

What will I be able to do after the Linux Administration for System Administrators course?

You will be able to install and configure Ubuntu or RHEL servers, manage files, permissions, users and sudo on least-privilege principles, install software with APT and DNF, run services with systemd, add and permanently mount disks, configure networking and firewalls, harden SSH, read logs and automate tasks with shell scripts. Participants who complete the training receive a Certificate of Completion with its own number, which can be verified online.

Can the Linux Administration for System Administrators course be run in-house for our team?

Yes. It can be run in-house for your team, with examples adapted to your own work, such as the Linux distribution and server configuration standards your team already uses. You can request a quotation from this page, or contact us on LINE @itgenius or by phone on 02-570-8449.
