Enterprise Linux Systems Administration

Available for RHEL· SLES

Master the full stack of enterprise Linux systems administration on your choice of Red Hat Enterprise Linux (RHEL) 9 or SUSE Linux Enterprise Server (SLES) 15. This course builds real operational depth: kernel and device management, systemd service control, GRUB2 boot configuration, and package management with RPM and distribution-specific tools, giving administrators the expertise that modern data center and hybrid cloud environments demand.

Coverage spans local storage administration with partitioning, XFS and ext4 filesystems, LVM thin provisioning, and software RAID, plus remote storage via NFS, autofs, iSCSI, and SAN multipathing. The security curriculum addresses SELinux policy management, AppArmor profiles, firewalld zones and rich rules, PAM authentication, and POSIX ACLs. Networking topics progress from interface configuration and routing through advanced areas including bonding, teaming, 802.1q VLANs, IPv6, DHCP server deployment, and kernel network tuning. Students also learn centralized log management with rsyslog, the systemd journal, and Cockpit, alongside system performance monitoring and troubleshooting techniques using sar, strace, and distribution rescue environments.

Every chapter pairs instructor-led instruction with guided lab exercises on live systems. With 14 chapters and over 60 hands-on labs covering real-world scenarios, from recovering unbootable systems to configuring iSCSI storage and tuning network performance, students leave with the practical skills to confidently administer Linux servers in production.

Who Should Attend

System administrators, DevOps engineers, site reliability engineers, and IT infrastructure professionals responsible for deploying, configuring, and maintaining enterprise Linux servers. This course also benefits software developers and cloud engineers who need deep operational knowledge of Linux system internals, storage management, and security hardening.
