Enterprise Linux 7
Systems Administration Rapid Track
(RH199 RHCSA equivalent for RedHat, CentOS,
Oracle and Scientific Linux versions)
This five day course covers
essential administration skills including local
storage management; network and network services
configuration; remote access using SSH, VNC,
FTP; web services configuration; firewall and
SELinux management; KVM VM deployment and
management; installing the OS using Kickstart.
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, Oracle Enterprise
Linux (OEL) and Scientific Linux.
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
