2.7 Installation of HA Cluster Packages

To install the Linux HA cluster system, the following packages are needed:

 rgmanager

rgmanager is the Resource Group (Service) Manager. It controls starting, stopping,

migrating, relocating, and recovering services with the HA cluster.

 lvm2-cluster

The lvm2-cluster package contains support for Logical Volume Management (LVM) in a

clustered environment.

 gfs2utils

The gfs2utils package contains a number of utilities for creating, checking, modifying,

and correcting any inconsistencies in global filesystem (GFS2) filesystems.

 ccs/luci/ricci

The CCS (cluster configuration system) allows an administrator to create, modify, and

view a cluster configuration file on a remote node through ricci or a local file. Luci is web

frontend providing HA cluster suite management GUI. It is a required prerequisite to

have ricci package deployed and started on respective nodes before the cluster can be

managed with luci.

 cman

The Cluster Manager (cman) handles communications between nodes in the cluster,

determining when a node enters or leaves the cluster.

To help to resolve the complex dependency problem, the yum (Yellow Dog Updater Modified)

tool is often used to install the packages above. The packages are downloaded from collections

called repositories, which may be on internet, on a local network, or on installation media. If your

server has no internet access, or you cannot access to some public package repositories, local

installation media can be a better choice. The following steps show how to install these

packages from local media.

1. Verify that the yum tool has been installed on your Linux system.

2. Add a new file named local.repo in the folder /etc/yum.repos.d, with the

following contents:

[Server]

name=Server

baseurl=file:///media/CDROM/Server

enable=1

gpgcheck=0

[HighAvailability]

name=HighAvailability

baseurl=file:///media/CDROM/HighAvailability

enable=1

gpgcheck=0

[LoadBalancer]

name=LoadBalancer
