Abstract
A Heartbeat cluster can be installed and configured using YaST. During the Heartbeat installation, you are prompted for information that is necessary for Heartbeat to function properly. This chapter contains information to help you install, set up, and configure a Heartbeat cluster. Learn about the hardware and software requirements and which preparations to take before installing Heartbeat. Find detailed information about the installation process and the configuration of a STONITH device.
![[Note]](admon/note.png) | Installing Heartbeat Software Packages on Cluster Nodes |
|---|---|
This Heartbeat installation program does not copy the Heartbeat software package to cluster nodes. Prior to running the installation program, the Heartbeat software package must be installed on all nodes that will be part of your cluster. This can be done during the SUSE Linux Enterprise Server 10 installation, or after. | |
The Heartbeat installation program lets you create a new cluster or add nodes to an existing cluster. To add new nodes to an existing cluster, you must run the installation program from a node that is already in the cluster, not on a node that you want to add to the cluster.
After installing Heartbeat, you need to create and configure cluster resources. You might also need to create file systems on a shared disk (Storage Area Network, SAN) if they do not already exist and, if necessary, configure those file systems as Heartbeat cluster resources.
Both cluster-aware (OCFS 2) and non-cluster-aware file systems can be configured with Heartbeat. See the Oracle Cluster File System 2 Administration Guide for more information.
The following list specifies hardware requirements for a Heartbeat cluster. These requirements represent the minimum hardware configuration. Additional hardware might be necessary, depending on how you intend to use your Heartbeat cluster.
A minimum of two Linux servers. The servers do not require identical hardware (memory, disk space, etc.).
At least two communication media (Ethernet, etc.) that allow cluster nodes to communicate with each other. The communication media should support a data rate of 100 Mbit/s or higher.
A STONITH device.
