Uninstalling NRPE
This document describes how to uninstall NRPE that is installed from source. The installation could have been performed using the linux-nrpe-agent that ships with Nagios xi OR directly from the source files. This KB article does not apply if you have installed NRPE using your operating system (OS) package manager like yum.
The steps in this KB article could lead to unexpected results if you are not familiar with the commands being executed. If you are unsure about the steps being provided it is recommended to seek advice from the Nagios Support Forums before proceeding.
DO NOT follow this procedure on your Nagios xi server! NRPE is a part of Nagios xi and performing the commands in this KB article can result in a broken Nagios xi server.
This guide is broken up into several sections and covers different Linux distributions and non-Linux operating systems.
It is assumed that you are logged onto the machine as the root user, or a user with sufficient privileges. Some OS's like Ubuntu and SUSE have stricter user permissions, in those cases the listed commands have sudo in front of them to ensure you are able to complete the steps. A best effort has been made to ensure if you follow all the relevant steps you will completely remove NRPE.
Please select your OS:
Identify NRPE Daemon
NRPE can be running as a dedicated service or via the xiNETD daemon. You must identify this as the steps to stop and remove the service will be different. To identify if you are using xiNETD execute the following command:
file /etc/xinetd.d/nrpe
This output indicates that you are using xiNETD:
/etc/xinetd.d/nrpe: ASCII text
Follow the xiNETD steps below.
This output indicates that you are NOT using xiNETD and hence must be using a dedicated service:
/etc/xinetd.d/nrpe: cannot open `/etc/xinetd.d/nrpe' (No such file or directory)
Follow the dedicated daemon steps below.
Stop And Remove xiNETD Daemon
Execute these commands to stop xiNETD from running NRPE.
Delete the configuration file:
rm -f /etc/xinetd.d/nrpe
Restart the xiNETD daemon depending on your operating system version:
===== CentOS 5.x / 6x | RHEL 5.x / 6x | Oracle Linux 5.x / 6x =====
service xinetd restart
===== CentOS 7.x | RHEL 7.x | Oracle Linux 7.x =====
systemctl restart xinetd.service
Stop And Remove Dedicated Daemon
Execute these commands to stop, disable and remove the NRPE service, depending on your operating system version:
===== CentOS 5.x | RHEL 5.x | Oracle Linux 5.x =====
service nrpe stop
chkconfig nrpe off
rm -f /etc/init.d/nrpe
===== CentOS 6.x | RHEL 6.x | Oracle Linux 6.x =====
stop nrpe
rm -f /etc/init/nrpe.conf
===== CentOS 7.x | RHEL 7.x | Oracle Linux 7.x =====
systemctl stop nrpe.service
systemctl disable nrpe.service
rm -f /usr/lib/systemd/system/nrpe.service
systemctl daemon-reload
