Linux: Kernels and Logging for System Administration

In order to gain a more holistic understanding of Linux, it’s crucial for system administrators to understand the mechanics of the operating system at its core—the Linux kernel. In this course, learn how to manage Linux kernels on Enterprise Linux, and manage the GRUB boot loader, system initialization, and system logging. Grant McWilliams explains how to fix a Linux installation issue by booting into the emergency target, and shows how to leverage systemd to help maintain system services. Along the way, explore Linux kernel versions and how to update the kernel and manage kernel modules. In conclusion, Grant covers the essentials of system logging, demonstrating how to search and rotate log files, make journald logs persistent, use rsyslog filters, and more.
