After you performed this fullinstall, an NRPE binary should have been generated in the src directory of the folder than you ran ./fullinstall from. You should be able to simply copy that binary to /usr/local/nagios/bin/nrpe. Give the following a try:

Code: Select all

find / -name nrpe -type f

Code: Select all

cp /example/nrpe/src/nrpe /usr/local/nagios/bin/

Hi ,

Please find the results below.

# find / -name nrpe -type f
/etc/xinetd.d/nrpe
/tmp/linux-nrpe-agent/subcomponents/nrpe/nrpe-2.15/package/solaris/pkg/nrpe


"nrpe " is not available in the installed path

Thanks,

Try installing NRPE by running:

Code: Select all

cd /tmp/linux-nrpe-agent/subcomponents/nrpe/
./install

Post the output in case you see any errors.

The install log shows that the SSL headers are not installed on your system so can you login as root and run the following?

Code: Select all

yum install openssl-devel -y

After they are installed, you will have to go to the source folder and re-run the fullinstall

Code: Select all

cd /tmp/linux-nrpe-agent
./fullinstall

Post back any errors if you receive any.

Hi ,Thanks for the response. I manually installed openssl-devel and nrpe as suggested . After that nrpe client started working .
Do I need to perform the same for all clients whenever installing nagios agent . Kindly advice .
