Book description
Leverage the power of high availability clusters on CentOS Linux, the enterprise-class, open source operating system
In Detail
The high performance and stability of CentOS Linux are the key factors that make CentOS Linux the right Linux distribution to build high availability solutions on. This book introduces you to high availability before briefly walking you through the cluster stack and its layers. The book is then divided into two parts, part A and part B, based on CentOS versions 6 and 7 respectively. Each part begins with the installation and configuration of the Corosync cluster messaging software with CMAN or with the Pacemaker cluster resource management software.
You will also be introduced to cluster service configuration and cluster service management before you configure fencing or STONITH on CentOS 6 and CentOS 7. By the end of this book, you will have the skills required to independently design, implement, and maintain a CentOS high availability multinode cluster environment.
What You Will Learn
- Prepare the CentOS 6 and CentOS 7 operating systems for cluster software installation
- Install, configure, and test cluster stacks on CentOS 6 (Corosync, CMAN, and RGManager) and CentOS 7 (Corosync and Pacemaker)
