Created October 15, 2013 11:28
Download and Install Nagios client plugin along with NRPE plugin. This script is written for a Ubuntu server but you can easily modify it to suit your needs. Post installation, modify `/etc/xinetd.d/nrpe` to restrict request origin, update `/etc/services` to add `nrpe` service.
#!/bin/bash
# Nagios client install script
# Vinayak Mishra <[email protected]>
set -e -x
# ensure only root can run the script
if [[ $EUID -ne 0 ]]; then
echo "This script must be run as root"
exit 1
