RHEL

Pacemaker has been available for Red Hat Enterprise Linux (RHEL) since version 6.0 as part of the High Availability Add-On (initially as a Technology Preview, then with full support).

Users who purchase the add-on get the full value of a Red Hat subscription, including support, certifications, training, RHEL-specific documentation, and so on.

Users who are willing to forego that level of support have other options:

1. Install from the RHEL install media
2. Install from the CentOS or Scientific Linux repos
3. Download and rebuild the necessary SRPMs from the Red Hat FTP server

As an example, using the CentOS repository:

cat >/etc/yum.repo.d/CentOS-Base.repo <<EOF
[centos-base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
enabled=0
EOF

yum install --enablerepo=centos-base pacemaker
