The redundancy of multiple machines is used to guard +against failures of many types. + +This document will walk through the installation and setup of simple +clusters using the |CFS_DISTRO| distribution, version |CFS_DISTRO_VER|. + +The clusters described here will use Pacemaker and Corosync to provide +resource management and messaging. Required packages and modifications +to their configuration files are described along with the use of the +``pcs`` command line tool for generating the XML used for cluster +control. + +Pacemaker is a central component and provides the resource management +required in these systems. This management includes detecting and +recovering from the failure of various nodes, resources, and services +under its control. + +When more in-depth information is required, and for real-world usage, +please refer to the `Pacemaker Explained <https://www.clusterlabs.org/pacemaker/doc/>`_ +manual. + +.. include:: ../shared/pacemaker-intro.rst |
