1 GL-280: Red Hat Linux 7 Update Course Description This is a differences course that focuses on the new technologies and features that made their appearance in Red Hat Enterprise Linux v7. It is intended for system administrators and developers who are comfortable with RHEL6 and wish to update their skills on the new topics. The notable new features covered in this course include the new system and service manager Systemd, the GRUB2 boot manager, new Dracut the reworked and standardized /etc configuration files, UDEV changes, storage enhancements such as Automated Storage Tiering, Thin Provisioning, Device Mapper dm-raid target, and the XFS filesystem. Other new networking features are covered such as the systemd-udev NIC naming scheme, nmcli, and the new Network Teaming system. Additional new management and monitoring tools are covered such as the new polkit javascript authorization system, the new cgroups architecture, FirewallD and the systemd journal, and new advanced input and output modules for rsyslog. Finally, an overview of the Linux container ecosystem and an excellent introduction to Docker is included in this course. Prerequisites: This course requires an advanced knowledge of Red Hat Enterprise Linux System Administration v6 or earlier. These skills are taught in the GL250 "Enterprise Linux Systems Administration" and GL120 "Linux Fundamentals" courses. Supported Distributions: Red Hat Enterprise Linux 7 Course Outline 1.
