Enterprise Linux 8 Systems Administration Part 2
(RH134 RHCSA equivalent for RedHat, CentOS and Oracle versions, as updated October 2020)

This five-day course covers the additional essential administration features of Enterprise Linux 8 for those who have attended the Part 1 Administration course, or who already have knowledge and experience to that level. As with all our other courses, students have exclusive use of deskside servers, plus additional VMware ESXi hosted virtual machines.

Topics include interactive and automated OS install using the Kickstart mechanism, file system and logical volume management, advanced disk facilities (Stratis and VDO) scheduled job management, network file system configuration and management, configure and manage the SELinux security features, creating and managing a firewall based on firewalld, along with a variety of troubleshooting scenarios. Newly added in October 2020 are Container Management with podman, and basic shell scripting
The course is fairly intensive, but provides ample time for putting skills into practise.

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

This course helps with the preparation for several certifications, but is aimed mainly at RedHat Certified System Administrator (RHCSA) when combined with the Linux Enterprise Administration Part 1 course. The course is suitable for any RedHat or rebuild distribution such as CentOS and Oracle Linux (OL).

Our Linux courses are suitable training for Linux LPI or RedHat Certification
