Installing Munin

Due to :ref:`Munin's Architecture <architecture-index>` you have to install two different software packages depending on the role, that the machine will play.

You will need to install "munin-master" on the machine that will collect data from all nodes, and graph the results. When starting with Munin, it should be enough to install the Munin master on one server.

The munin master runs :ref:`munin-httpd` which is a basic webserver which provides the munin web interface on port 4948/tcp.

Install "munin-node" on the machines that shall be monitored by Munin.

Source or packages?

With open source software, you can choose to install binary packages or install from source-code.


We strongly recommend a packaged install, as the source distribution isn't as tested as the packaged one. The current state of the packages is so satisfactory, that even the developers use them instead.

Installing Munin on most relevant operating systems can usually be done with with the systems package manager, typical examples being:

Installing Munin from a package


From source:

cd /usr/ports/sysutils/munin-master && make install clean
cd /usr/ports/sysutils/munin-node && make install clean

Binary packages:

pkg install munin-master
pkg install munin-node


Munin is distributed with both Debian and Ubuntu.

In order to get Munin up and running type

sudo apt-get install munin-node

on all nodes, and

sudo apt-get install munin

on the master.

Please note that this might not be the latest version of Munin. On Debian you have the option of enabling "backports", which may give access to later versions of Munin.

RedHat / CentOS / Fedora

Current versions are available at EPEL.

In order to install Munin type

sudo yum install munin-node

on all nodes, and

sudo yum install munin

on the master.

You will have to enable the services in systemd to get them up and running.

Likely you will have to fix SELinux issues when using 3rd-Party plugins and SELinux active and set to enforcing mode on the Munin node. In case you get competent and friendly support on SELinux mailinglist.

Other systems

On other systems, you are probably best off compiling your own code. See Installing Munin from source.

Installing Munin from source


Usually you don't want to do that. The following lines are for completeness, and reference for packagers.

The other reason would be because you want to contribute to the development of Munin, and then you should use a development install.

If there are no binary packages available for your system, or if you want to install Munin from source for other reasons, follow these steps:

We recommend downloading a release tarball, which you can find on

Alternatively, if you want to hack on Munin, you should clone our git repository by doing.

git clone git://

Please note that a git checkout will need some more build-dependencies than listed below, in particular the Python Docutils and Sphinx.

Build dependencies on Debian / Ubuntu

In order to build Munin from source you need a number of packages installed. On a Debian or Ubuntu system these are:

  • perl
  • htmldoc
  • html2text
  • default-jdk

Configuring and installing

Warning for NFS users

If you're using NFS please note that the "make install" process is slightly problematic in that it (Module::Build actually) writes files under $CWD. Since "make install" is usually run by root and root usually cannot write files on a NFS volume, this will fail. If you use NFS please install munin from /var/tmp, /tmp or some such to work around this.

Running make

There are make targets for node, master, documentation and man files. Generally you want to install everything on the master, and just the node and plugins on the nodes.

  • Edit Makefile.config to suit your needs.

  • Create the user "munin" with the primary group "munin".

    The user needs no shell and no privileges. On most Linux systems the munin user's shell is the nologin shell (it has different paths on different systems - but the user still needs to be able to run cron jobs.


For the node, you need only the common parts, the node and the plugins.

make install-common-prime install-node-prime install-plugins-prime


For the master, this will install everything.

make install
