Opis

Deploy reliable, available critical production services in a high availability cluster

In the Red Hat High Availability Clustering with exam (RH437) course, you will learn how to provide highly available network services to a mission-critical enterprise environment through the deployment and management of shared storage and server clusters. Created for senior Linux system administrators, this 4-day course strongly emphasizes lab-based activities. You will set up a cluster of systems running the Pacemaker component of the Red Hat Enterprise Linux High-Availability Add-On, and deploy Linux-based services such as web servers and databases on that cluster. Cluster storage components from the Resilient Storage Add-On are also covered; installations and applications that require multiple cluster nodes can access the same storage simultaneously. This includes Logical Volume Manager (LVM) Shared Volume Groups, Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath.

This course is based on Red Hat Enterprise Linux 8.3. This version of the course includes the EX436 Red Hat Certified Specialist in High Availability Clustering 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
  • Implement Logical Volume Manager (LVM) in cluster-aware configurations
  • Configure GFS2 file systems on storage shared by multiple nodes

Cel

Impact on the organization

High availability clustering can improve reliability, availability, and resiliency of your mission-critical services, resulting in reduced downtime and easier hardware maintenance.

Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.

Impact on the individual

As a result of attending this course, you will 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 an high availability environment using iSCSI initiators, HA-LVM or LVM Shared Volume Groups as appropriate, and GFS2 cluster file systems.
  • Implement strategies to identify and eliminate single points of failure in high availability clusters.

Grupa docelowa:

  • Senior Linux system administrators who use high-availability clustering and fault-tolerant shared storage technologies to maximize resiliency of production services.

Uwagi:

Szkolenie trwa 5 dni (classroom, VT, bundle).

  2. Managing cluster nodes and quorum
    • Manage node membership in the cluster and describe how it impacts cluster operation.
  3. Isolating malfunctioning cluster nodes
    • Isolate unresponsive cluster nodes to protect data and recover services and resources after a failure.
  4. Creating and configuring resources
    • Create basic resources and resource groups to provide highly available services.
  5. Troubleshooting high availability clusters
    • Identify, diagnose, and fix cluster issues.
  6. Automating cluster and resource deployment
    • Deploy a new high availability cluster and cluster resources using Ansible automation.
  7. Managing two-node clusters
    • Operate two-node clusters while identifying and avoiding issues specific to a two-node cluster configuration.
  8. Accessing iSCSI storage
    • Configure iSCSI initiators on your servers to access block-based storage devices provided by network storage arrays or Ceph storage clusters.
  9. Accessing storage devices resiliently
    • Configure resilient access to storage devices that have multiple access paths.
  10. Configuring LVM in clusters
    • Select, configure, and manage the correct LVM configuration for use in your cluster.
  11. Providing storage with the GFS2 cluster file system
    • Use the GFS2 cluster file system to simultaneously provide tightly coupled shared storage that can be accessed by multiple nodes.
  12. Eliminating single points of failure
    • Identify and eliminate single points of failure in your cluster to decrease risk and increase average service availability.
