Install Munin to see server's status!

Installation on CentOS 5


The easiest way to go about this is to install a YUM repository that contains it. The two most popular are the EPEL YUM Repository from the Fedora Core team, and the Dag Wieers YUM repository
Once the repository is installed, just use YUM to install both the munin and munin-node RPMs as required.
Installing the EPEL YUM Repository


Just execute this command as root :

rpm -Uvh http://download.fedora.redhat.com/pu...5-3.noarch.rpm

That is of course if you are running CentOS 5.3. Change the file name to 5.2 if you are running that release, and so on.

Installing the Dag Wieers YUM Repository


Just create the following file with the contents show : /etc/yum.repos.d/dag.repo

[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
gpgkey=http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
enabled=1

Installing Client and Server ¶

On the server, just do :

yum -y install munin

And on each client (or "node" as munin calls them) :

yum -y install munin-node

Note that the node install can take a really long time to complete - just be patient and it will.



Configuration on CentOS 5

[root@ns ~]# vi /etc/munin/munin.conf

htmldir /var/www/munin // line 7: change
