Enterprise Linux 7 New Features for Administrators
(For RedHat 7, CentOS 7, Oracle Linux 7 and Scientific Linux 7 versions)

This three-day course covers the new administration features of Enterprise Linux 7 for those with previous Enterprise Linux 5 and 6 administration experience.
The course is fairly intensive, but provides ample time for putting skills into practise. Topics include the GRUB2 bootloader, the new systemd boot process and service management, creating new services, new network commands (nmcli, nmtui, hostnamectl) and network teaming/bonding, firewalld-based Linux firewall facilities using firewall-cmd, Interactive installation plus Kickstart differences, an introduction to Control Groups, journald logging, chronyd times services, Btrfs and XFS file systems, and more.

In addition, a variety of troubleshooting scenarios are covered, and methods for system performance monitoring.
 We use real hardware, with each attendee having their own dedicated server throughout the course, plus access to additional virtual machines on a VMWare server.

This course is available to be run, fully resourced, at your site; see here for on-site details and prices.
