Ganglia installation on CentOS

I am assuming that we are going to implement it on CentOS/RHEL box. And Ganglia doesn’t come with those. So we need to get the software through EPEL reposity or alternatively from here :

http://rpmfind.net/linux/rpm2html/search.php?query=ganglia-gmetad

Or if we are inclined get it installed from the source then we need to look here for tar [file: http://ganglia.info/?page_id=66%5D

Step 1:

Installing Ganglia:

[bhaskar@Amazon-instances ~]$ sudo yum install ganglia ganglia-gmetad ganglia-gmond ganglia-web

Step 2:

Setting password for user ganglia:

[bhaskar@Amazon-instances ~]$ sudo /usr/bin/passwd ganglia
Changing password for user ganglia.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.


Step 3:

Starting gmond daemon at boot:

[bhaskar@Amazon-instances ~]$ sudo /sbin/chkconfig --levels 235 gmond on

Step 4:

Started gmond daemon :

[bhaskar@Amazon-instances ~]$ sudo /sbin/service gmond start
Starting GANGLIA gmond: [ OK ]

step 5:

configure this file :

[bhaskar@Amazon-instances ~]$ sudo vim /etc/gmetad.conf

step 6:
configure this daemon too:

[bhaskar@Amazon-instances ~]$ sudo /sbin/chkconfig --levels 235 gmetad on

step 7:
Starting gmetad daemon:

[bhaskar@Amazon-instances ~]$ sudo /sbin/service gmetad start
Starting GANGLIA gmetad: [ OK ]

Step 8:
Installing gmond on different node:

Step 9:
Run it different level:

[bhaskar@Amazon-instances ~]$ sudo /sbin/chkconfig --levels 235 gmond on

Step 10:

Come back to the main machine ,where ganglia install and do the following:

Change the ownership of ganglia directory to ganglia user and group:

[bhaskar@Amazon-instances html]$ sudo chown -R ganglia:ganglia ganglia/

Add ganglia user to the apache group:

[bhaskar@Amazon-instances html]$ sudo /usr/sbin/usermod -G apache -a ganglia

Check the ganglia id:

[bhaskar@Amazon-instances html]$ id ganglia

uid=102(ganglia) gid=103(ganglia) groups=48(apache),103(ganglia)

[bhaskarc@Amazon-instances html]$ sudo chown -R ganglia:ganglia ganglia/
[bhaskar@Amazon-instances html]$ sudo /usr/sbin/usermod -G apache -a ganglia
[bhaskar@Amazon-instances html]$ id ganglia
uid=102(ganglia) gid=103(ganglia) groups=48(apache),103(ganglia)

Step 11:

You can view ganglia with this url:

http://Amazon-instances.amazonaws.com/ganglia/

It should show you the graph.

Hope this will help.

Cheers!
