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

This four-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.
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

OBJECTIVES OF THE COURSE

To become proficient in Linux Enterprise administration to a level required for the RedHat RHCSA exam.

COURSE DATES: This course is only available at the client site, fully resourced. Dates by arrangement.

INTENSITY: About 30% of the course is practicals, and 70% lectures

RESOURCE: Each student will have exclusive use of a fully equipped Dell server for the duration of the course, plus ESXi hosted VMs. Each student will be provided with a full set of training notes, and quick reference cards to assist with file editing and Linux commands. A full reference for Linux resources will also be provided in the notes.

PREREQUISITES: Knowledge to a level taught on the Enterprise Linux 8 Administration Part 1 course.

FOLLOW UPS: Enterprise Linux Adminstration Part 3 for an RHCE-level course. First Alternative also offers an extensive range of Solaris courses but only on-site at client premises.

PRACTICALS / TAKEAWAYS: Each student leaves the course with their own set of training notes for the material covered; around 120 pages per day of training. Quick reference sheets are provided as appropriate.

Every student who attends this course will be issued with a signed certificate of course completion, which we will be happy to "authenticate" upon future request.

SOFTWARE VERSIONS: We currently use CentOS Linux 8 which is the equivalent to RedHat 8 and Oracle Linux 8. If you are a user of Scientific Linux, be aware that development was terminated at version 7, and Fermilabs began using CentOS instead.
