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

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
