Enterprise Linux 8
Systems Administration Rapid Track
(RH199 RHCSA equivalent for RedHat, CentOS and
Oracle versions)
This five day course covers
essential administration skills including local
storage management including Stratis; network
and network services configuration; remote
access using SSH; firewall and SELinux
management; KVM VM deployment and management;
installing the OS interactively and using
Kickstart. Newly added in October 2020 are
Containers with podman, buildah and skopeo.
It is intended for those who have
previous Linux or UNIX experience and are
comfortable using the command line and editing
text files.
The course is fairly intensive, but provides
ample time for putting skills into practise.
This course helps with the preparation for
several certifications, but is aimed mainly at
RedHat Certified System Administrator (RHCSA).
The course is suitable for any RedHat or rebuild
distribution such as CentOS and Oracle
Enterprise Linux (OEL). It is effectively the
Admin parts 1 and 2 courses delivered at an
accelerated pace.
We use real hardware and virtual
machines, with each attendee having their own
dedicated server throughout the course, plus
access to additional virtual machines on a
VMWare ESXi server..
This course is available to be
run, fully resourced, at your site; see here for on-site
details and prices.
Our Linux courses are suitable
training for Linux LPI or RedHat
Certification
