Before installing Munin on server01 apache2 will need to be installed. The default configuration is fine for running a munin server. For more information see „HTTPD - Apache2 web kiszolgáló”.

First, on server01 install munin. In a terminal enter:

sudo apt-get install munin

Now on server02 install the munin-node package:

sudo apt-get install munin-node

On server01 edit the /etc/munin/munin.conf adding the IP address for server02:

## First our "normal" host.
[server02]
       address 172.18.100.101

Next, configure munin-node on server02. Edit /etc/munin/munin-node.conf to allow access by server01:

allow ^172\.18\.100\.100$

Now restart munin-node on server02 for the changes to take effect:

sudo /etc/init.d/munin-node restart

Finally, in a browser go to http://server01/munin, and you should see links to nice graphs displaying information from the standard munin-plugins for disk, network, processes, and system.

The munin-plugins-extra package contains performance checks additional services such as DNS, DHCP, Samba, etc. To install the package, from a terminal enter:

sudo apt-get install munin-plugins-extra

Be sure to install the package on both the server and node machines.
