Can you check if it exists in the expected location (/usr/lib/systemd/system)? You can also verify if your packages are properly installed, by doing: rpm -V nrpe If that shows some files missing (such as the systemd unit file), then you're best of reinstalling nrpe with: yum reinstall nrpe Regards, Anand
