Binary Packages

Most Linux distributions do a good job of providing up-to-date binary packages for pacemaker and related components. Pacemaker is currently available on:

See quickstart guides for more information about installing on particular distributions.

RPM-based distributions


Pacemaker has been a part of the standard Fedora repositories since Fedora 12. To install:

yum install -y pacemaker corosync


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
name=CentOS-$releasever - Base

yum install --enablerepo=centos-base pacemaker

RHEL-compatible Distributions (CentOS, Scientific Linux, etc.)

As of version 6 of these distros, Pacemaker is part of the distribution and updates are usually quickly available via the regular channels. There is nothing extra to download, just run:

yum install -y pacemaker corosync


openSUSE uses zypper instead of yum, but the procedure is much the same:

zypper install pacemaker corosync

.deb-based distributions


See the Debian-HA wiki for the latest information.

Pacemaker and related components have been available from the standard Debian repositories for a long time, but were removed from Debian 8 ("jessie") due to packaging issues that were not resolved before release. For jessie, Pacemaker is available from Debian backports.

To install:

apt-get install pacemaker corosync

See also the Debian Lenny HowTo and instructions for Compiling on Debian.

If you run into any issues installing, updating, or using these packages, please let us know on our [Mailing lists].


As of Ubuntu 10.4 (Lucid Lynx), Pacemaker and all its dependancies are part of the distribution. Simply run:

aptitude install corosync pacemaker


aptitude install heartbeat pacemaker

Users of Ubuntu versions prior to 10.4 can either install the Debian packages, or try the ones from LaunchPad by adding

deb karmic main
deb-src karmic main

to /etc/apt/sources.list before running the same aptitude command above.


If no packages are available, you might need to install from source.

Next Steps

Once Pacemaker is installed, the next step is to configure your cluster stack. Check out our quickstart guides or the Initial Configuration page.
