What is Gmetad:
Gmetad runs on head node. It gathers data from all other nodes and stores them in round robin database. It can poll multiple clusters and aggregate the metrics. It is also used by the web frontend in generating the UI.

What is PHP Web Frontend:
The Ganglia web front-end provides a view of the gathered information via real-time dynamic web pages. Most importantly, it displays Ganglia data in a meaningful way for system administrators and computer users. It should be installed on the same machine where gmetad is installed.
Installation of ganglia on master node:
apt-get install ganglia-monitor rrdtool gmetad ganglia-webfrontend
In order to deploy and run Ganglia in Apache server, it is required to copy the apache.conf file from /etc/ganglia-webfrontend/apache.conf to /etc/apache2/sites-enabled/:
sudo cp /etc/ganglia-webfrontend/apache.conf /etc/apache2/sites-enabled/ganglia.conf
Installation of ganglia on other nodes:
apt-get install ganglia-monitor
The above command will install the ganglia monitor.
