Installing Ganglia on RHEL
This is a quick follow-up to my earlier post about installing Ganglia from source on SLES. Here we will install Ganglia from precompiled RPMs on an RHEL server. The basic cluster setup for this example remains the same: two clusters: CLUSTER1 and CLUSTER2 with head nodes head_node1 and head_node2. Each compute node runs Ganglia monitoring agent (gmond) and sends data to its respective head node. The main Ganglia server connects to each head node and pulls the performance data.
If your soon-to-be Ganglia server is behind a firewall, you will need to edit YUM’s config file to add you Web proxy. Vi the /etc/yum.conf and add the following:
proxy=http://:
You will also need to set the http_proxy for your shell:
export http_proxy=http://:
Now you will need to add the EPEL repository to YUM. To do this, download and install the epel-release-.noarch.rpm RPM appropriate for your RHEL version. Here’s an example:
wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm rpm -i epel-release-6-5.noarch.rpm
The next step is to install all the Ganglia packages for your server. These include data collection agent (gmetad), the monitoring daemon (gmond) and the PHP-driven Web front end.
yum install ganglia ganglia-gmetad ganglia-web ganglia-gmond
Once everything has been installed, you will need to edit the /etc/gmetad.conf as discussed in my previous post. You only need to activate the gmetad service. The gmond service is not needed on the Ganglia server in our configuration.
chkconfig gmetad on service gmetad restart
You will also need to activate and start your Apache Web server:
chkconfig httpd on service httpd restart
Now you should be able to access the Ganglia Web interface at http:///ganglia
thanks for posting this; followed all instructions and it’s working.
Version 3.07 got installed.
What would be the best method to upgrade to the new version?
I have a quarter sized lump on the bottom of my foot, kinda between the second and third toes. Family doc diagnosed it as a ganglion cyst and wants me to see a foot doctor. I have had this problem for about six weeks now and it seems to be much better than it was. Do they ever go away? I don’t see the foot doctor until the beginning of March. Any recommendations for at home treatment?
What are two diseases/viruses that lay within the Dorsal Root Ganglion? One of them is adult chicken pox I think but dont know the name of, anyone help?
Im studying for anatomy and we are on the spinal cord and in the dorsal root there is a ganglion but there isnt one in the ventral root and i cant tell why?
How long does it take to surgically remove a Ganglion Cyst within the wrist?
Which of the following parts of a reflex arc would have a cell body in the posterior root ganglion?
Several years ago I started getting Lipomas on my body, then a ganglion on my wrist and now I have found a Goiter on my thyroid. Sonogram on neck shows 4 lumps on one side of neck and 1 lump on other side.
Today in my nervous systems class we were talking about the cranial nerves. My professor said that only ANS nerves have ganglia in the PNS, and all sensory and somatic motor nerves synapse within the CNS. When we were looking at the vestibulcochlear nerve (cranial nerve 9) I noticed in the diagram the vestibular ganglia appeared to be in the PNS, but since this is a sensory only nerve, the ganglia should be in the CNS. I asked my professor about it after class, and he said it was a good question and that I should research it. I was wondering if anyone here has taken a neurobiology class and can help me out. Thanks in advance.
She stopped breathing after birth and has has a MRI diagnosing an insult to the basal ganglia,Does anyone know much about this condition and what should i expect..Anyone know of anyone with this condition …Any help greatly appreciated..
The doctors say incidentally I’ve been diagnosed with Bilateral Basal Ganglia Calcification. Can anyone explain to me what that is and is there a treatment and can I die from it?
I’m a bit confused with the terminology. When they mean lateral do they mean farther away and medial closer to? How does this make sense..if i’m not mistaken the basal ganglia is right above the temporal lobe region. I’m inclined to say the answer is medial (just because both regions are so close) am I correct?
I have this soft mass the size of walnut in my left groin. No pain just discomfort, like tightening. If I stretch my hips it hurts but if I press on it it doesn’t at all. When I lie down it feels all right. I had a infection not long ago si it could be a ganglia but it be hernia also! Same symptoms!
Great Article… Works as explained.. :)
