but I am still having problem with rrdltool
??

Do you know how?

.
# yum -y install rrdtool-devel

Or is it another problem but installing ? ?

its ok now all works fine

Sorry but am still newbie :)

Well, I had successfully installed munin, but can't view it on http://mywebsite.com/munin

should I create virtual host or edit somethng in conf files?
Thanks

Try to follow this, this seems to be much simple way to install munin.
