This Oracle Linux 7: Advanced Administration training is ideal for
experienced administrators who need to learn more about Oracle
Linux 7. You'll learn how to configure networking services and
authentication services, implement virtualization technologies to
more effectively manage system resources, perform advanced storage
administration tasks, implement shared storage technologies, and
develop advanced troubleshooting skills. In this course, you will
be introduced to the Oracle IaaS Cloud Solution.
Learn To:- ConfigureDNS, DHCP, http, Samba, and other network services.
- ConfigureLDAP, PAM, and other authentication services.
- Automateinstallation using Kickstart.
- Recoverfrom boot errors.
- Useadvanced package management features.
- Configurenetwork bonding, VLANs, and VPNs.
- ImplementLinux Containers, Docker, KVM and other virtualization services.
- Allocatesystem resources to specific Linux processes.
- UseDTrace to identify performance bottlenecks.
- ConfigureiSCSI, device multipathing, and OCFS2.
- Gain an understanding of the Oracle IaaS Cloud Solution.
Benefits to You After
taking this course, you will be equipped to use the advanced
features of Oracle Linux 7 to get the most out of your systems and
applications. You'll learn how to automate Oracle Linux
installations and implement networking and authentication services
to facilitate the management of a large number of systems. You'll
also learn how to use Control Groups, Linux Containers, Docker, and
KVM to increase your resource utilization by creating secure,
isolated environments on a single host. Become familiar with
advanced storage features, including encrypted file systems, disk
quotas, iSCSI, device multipathing, and the OCFS2 file system to
better use your storage resources. Gain
Hands-On Experience Extensive
hands-on practices will guide you through each concept. You will
configure network services and authentication services, configure
network storage, shared file system types, and device multipathing.
You will also configure different virtualization technologies to
better utilize system resources such as CPU, memory, network and
I/O bandwidth, and to allocate these system resources to critical
processes.
