Red Hat Certified Engineer (RHCE)

Overview

This course delivers a strong, practical foundation in Red Hat Enterprise Linux (RHEL) and core Linux administration skills — the essential building blocks for achieving RHCE certification.
It covers Linux/UNIX history, file system management, user & group administration, permissions, SELinux basics, LVM/RAID/swap, package management (RPM/YUM), networking tools, basic services (DNS caching, SSH, NFS, vsftpd, NTP), and scheduling tasks — all explained step-by-step with real commands and best practices.
Perfect for beginners, IT professionals switching to Linux, or anyone in Tokyo/Japan preparing for RHCE (EX294 or earlier tracks) and real-world Red Hat system administration jobs.

Key Features

🌐 Full coverage of core Linux/RHEL concepts — from boot process to advanced file systems and security

🔧 Hands-on command-line focus: useradd/usermod, chmod/chown, LVM/RAID creation, SELinux contexts, cron/at scheduling

⚡ Package & storage mastery: RPM/YUM, fdisk/mkfs/fsck, mount/fstab, disk quotas

📡 Networking & services basics: ifconfig, DHCP client/server, caching DNS (BIND), SSH/OpenSSH, NFS mounts, vsftpd setup

🛡️ Security essentials: SELinux modes/contexts, file permissions (setuid/setgid/umask), password aging

😊 Beginner-friendly — starts with Linux history and basic commands, builds progressively to RHCE-level topics

🚀 Excellent prep for RHCSA/RHCE exams and real enterprise Linux admin roles
