Linux High Availability Clustering on RHEL 8

Understanding Linux Clusters for High Availability

This course dives into the world of Linux clusters, exploring how to build and configure robust, highly available systems. Learn how to eliminate single points of failure and ensure continuous service operation through automated failover mechanisms.

What is a Linux Cluster?

A Linux cluster is a group of interconnected computers that work together as a single system. A key benefit is high availability, meaning your services remain accessible even if individual nodes experience issues. This is achieved by automatically shifting workloads and services to healthy nodes. Crucially, these clusters maintain data integrity during failover, ensuring no data loss. Clients remain unaware of node failures, providing a seamless user experience. The Pacemaker service is a vital component in managing high availability services within a cluster.

Course Curriculum:

This course provides a comprehensive understanding of Linux clusters, covering the following key areas:

• Building a Lab Environment: We'll guide you through setting up a practical lab using VMware Workstation and Nested ESXi Server. You'll learn to create virtual machines that will serve as the nodes in your cluster.
• Network Configuration for High Availability: Understand the necessary networking setup to enable reliable communication and failover between cluster nodes.
• Repository Server Configuration (RHEL 8): Learn how to configure a repository server on RHEL 8, a critical step for managing software updates and ensuring consistency across your cluster.
• Cluster Types: Explore various cluster types, including:
  • Storage Clusters: Utilizing iSCSI networks for centralized storage solutions.
  • High Availability Clusters: A deep dive into the cluster software components and their communication protocols. Understand how these components work together to ensure continuous service availability.
  • Load Balancing Clusters: Distribute workloads across multiple servers to improve performance and responsiveness.
  • High-Performance Clusters: Explore architectures optimized for demanding computational tasks. (Detailed information available within the course content.)
