cd nrpe

sudo make install-daemon-config

4, Start nrpe

vi /usr/local/nagios/etc/nrpe.cfg

allowed_hosts=127.0.0.1,123.12.1.2

123.12.1.2 is your nagios server address

start nagios:

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

Check the nrpe on nagios server

/usr/local/nagios/libexec/check_nrpe -H 123.12.1.5

123.12.1.5 is the ip adress of the nrpe deamon(the remote pc)

You should see something like:

NRPE v2.9

Congratulate! your nrpe works now.
