How To Install Munin on Ubuntu 14.04

Install Munin on Ubuntu 14.04

In this tutorial, we will show you how to install Munin on Ubuntu 14.04. For those of you who didn’t know, Munin is a free and open-source networked resource monitoring tool. It offers to monitor and alerting services for servers, switches, applications, and services. Munin uses the RRDtool to create graphs that are accessible over a web browser. Also, Munin can be configured to send alerts when some service/application, etc. is not working and Munin will automatically send an additional email alert once the problem has been resolved.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you the step-by-step installation of Munin on the ubuntu 14.04 server.


  • A server running one of the following operating systems: Ubuntu 14.04, and any other Debian-based distribution.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Munin on Ubuntu 14.04

Step 1. First, make sure that all your system packages are up-to-date by running the following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Install Apache which is available from the Ubuntu repositories.

apt-get install apache2

Step 3. Install Munin.

Install Munin and extra plugins using the following command:

apt-get install munin munin-node munin-plugins-extra

Step 4. Configuring Apache webserver.

Next, you will be editing Munin’s apache configuration file to point apache in the right direction when you request the monitoring information:

mv /etc/munin/apache.conf /etc/munin/apache.conf.bak

Edit the ‘/etc/munin/apache.conf’ configuration file and add the following lines:

#nano /etc/munin/apache.conf
<VirtualHost *:80>
      DocumentRoot "/var/cache/munin/www"
      DirectoryIndex index.html

   <Directory "/var/cache/munin/www">
      Options Indexes Includes FollowSymLinks MultiViews
      AllowOverride AuthConfig
      AuthUserFile /etc/munin/htpasswd
      AuthName "munin"
      AuthType Basic
      Require valid-user
      Order allow,deny
      Allow from all

   CustomLog /var/log/apache2/ combined
   ErrorLog /var/log/apache2/

   <Directory "/etc/munin/static">
      Require all granted

   <Directory "/usr/lib/munin/cgi">
      Options +ExecCGI
      Require all granted
   <IfModule mod_fcgid.c>
      SetHandler fcgid-script
   <IfModule !mod_fcgid.c>
      SetHandler cgi-script

Step 5. Configuring the Munin server.

Create the directory path that you referenced in the munin.conf file and modify the ownership to allow Munin to write to it:

sudo mkdir /var/cache/munin/www/
sudo chown munin:munin -R /var/cache/munin/www

Create a backup of the original Munin configuration file:

cp /etc/munin/munin.conf /etc/munin/munin.conf.orig

Edit the Munin configuration file and add/modify the following lines:

#nano /etc/munin/munin.conf

dbdir /var/lib/munin
htmldir /var/cache/munin/www
logdir /var/log/munin
rundir /var/run/munin
tmpldir /etc/munin/templates

includedir /etc/munin/conf.d

graph_strategy cron
cgiurl_graph /munin-cgi/munin-cgi-graph
html_strategy cron

    use_node_name yes

Create a password for the Munin administrator user:

htpasswd -c /etc/munin/htpasswd munin

Step 6. Start Apache and Munin services.

service apache2 start
service munin-node start

If all is well, open Munin at using ‘munin’ as username and the previously generated Munin password as password and you will be able to access Munin graphs and data.
