Nagios Log Server – Adding Additional
Instances To Cluster
The Industry Standard in IT Infrastructure Monitoring
Purpose
This document describes how to manually install Nagios Log Server from source, and join it to a preexisting cluster. These directions
assume that you are using a current and supported version of RHEL or CENTOS. Nagios Log Server is supported only on RHEL and
CentOS Linux servers.
Target Audience
This document is written for administrators who are looking to add additional instances to a Nagios Log Server cluster from source,
rather than using a pre-configured virtual machine image.
Shell Access
These instructions require you to have shell access to the server you plan to install Nagios Log Server on. You will need to login to your
server as the root user to perform an installation.
Items Needed
You will need to have on hand the IP address or host name of an existing instance in the cluster as well as the cluster ID which can be
found under Administration > Cluster Status from any existing instance in the cluster.
Install Nagios Log Server
Next, install Nagios Log Server from source by issuing the following commands at the shell prompt:
cd /tmp
wget http://assets.nagios.com/downloads/nagios-log-server/nagioslogserver-latest.tar.gz
tar xzf nagioslogserver-latest.tar.gz
cd nagioslogserver
./fullinstall
Nagios Log Server should now be installed on your system. You can access the Nagios Log Server web interface by browsing to the
following URL in your web browser:
http://<yournewinstanceip>/nagioslogserver

Nagios Log Server – Adding Additional
Instances To Cluster
Once you navigate to the URL of your
new Nagios Log Server instance you will
see a page like this:
As mentioned before you will need the IP address or hostname of an existing instance in your cluster and the Cluster ID which is
located in your current installation of Nagios Log Server under Administration > Cluster Status as shown in the example below.
As you can see above the Cluster ID is located next to the Cluster Status panel on the top of the Cluster Status page. Once you get the
ID all you need for the 'Hostname' section is a valid hostname or the IP address of the server you used to look up the Cluster ID. Once
you have entered the required information, click Finish Installation, and this new instance should now be hooked into your Nagios Log
Server cluster.
