pacemaker is Scalable High-Availability cluster resource manager
Introduction
In this tutorial we learn how to install pacemaker on CentOS 8.
What is pacemaker
Pacemaker is an advanced, scalable High-Availability cluster resource manager. It supports more than 16 node clusters with significant capabilities for managing resources and dependencies. It will run scripts at initialization, when machines go up or down, when related resources fail and can be configured to periodically check resource health. Available rpmbuild rebuild options –with(out) profiling
We can use yum or dnf to install pacemaker on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install pacemaker.
Install pacemaker on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
