Summary

In this chapter, we covered operating system preparation and cluster stack software installation on CentOS 7. We also provided a step-by-step guide on how to install and configure the Corosync cluster messaging software and the Pacemaker cluster resource management software with the pcs shell. We ended the chapter with the operational configuration of the Pacemaker cluster, ready to configure and provide the cluster service. In the next chapter, we will proceed with configuring cluster resources and cluster resource groups, and managing them around the cluster.
