RH437 : Red Hat High Availability Clustering with exam

WHAT YOU WILL LEARN

Created for senior Linux® system administrators, this 4-day course strongly emphasizes lab-based activities. You'll learn how to deploy and manage shared storage and server clusters that provide highly available network services to a mission-critical enterprise environment.


This course also helps you prepare for the Red Hat Certified Specialist in High Availability Clustering exam (EX436). This version of the course includes the exam.
Content summary
• Install and configure a Pacemaker-based high availability cluster
• Create and manage highly available services
• Troubleshoot common cluster issues
• Work with shared storage (iSCSI) and configure multipathing
• Configure GFS2 file systems

AUDIENCE

Senior Linux system administrators responsible for maximizing resiliency though high-availability clustering services and using fault-tolerant shared storage technologies.

PREREQUISITES

Senior Linux system administrators responsible for maximizing resiliency though high-availability clustering services and using fault-tolerant shared storage technologies

METHODOLOGY

This program will be conducted with interactive lectures, PowerPoint presentation, discussion and practical exercise.

COURSE OBJECTIVES

As a result of attending this course, students should be able to create, manage, and troubleshoot highly available network services and tightly coupled cluster storage for business-critical applications.


Students should be able to demonstrate the following skills:

• Improve application uptime by using high-availability clustering

• Manage storage in a high-availability environment using iSCSI initiators, HA-LVM or CLVM as appropriate, and GFS2 cluster file systems

• Implement strategies to identify single points of failure in high-availability clusters, and eliminate them

Since 1996, Adrian has been working with Linux – both in his professional capacity as a System Admin in the companies he had worked for as well as his hobby during his spare time. He has built a secure Linux firewall (based on the Slackware distro) on a 486 machine in 1998 which served as his company's main Internet gateway.Since then, he has taught himself PHP programming & developed a fully functional web-based “Staff Leave Application" for his company's internal use, built and sold commercial grade scripts used by online-marketers as well as designed and implemented highly-available MySQL replication across geographical data-centers with automated fail-over monitoring and triggering.In addition to the Linux (RedHat)/System Administration skills, Adrian is also well-versed in the web-application layer, i.e. the LAMP (Linux, Apache, MySQL, PHP) stack. One of his projects which utilizes both skill-sets is the development of the Afterschool.com Education portal which is a custom built Wordpress theme that runs an optimized LAMP stack on secured CentOS server.A strong advocate for the Open Source movement, Adrian's venture into professional training & education is a natural progression in his passion to share his knowledge and experience with others.
