NRPE support for el7

[eddiez]

We been building new Linux hosts with RedHat el7 version. When I go to install nrpe, I get the message ""el7 is not currently supported".

Is there a newer nrpe version that can use for this, or is there something differently I need to do.

Thanks,

Ed

When I went to install the downloaded nrpe, the installation failed. Here is output of the install.log

FirewallD is not running

[hsmith]

Can you please go to the directory you're installing NRPE from, and do a 'touch installed.firewall' command, and try to run the installer again?

[lmiltchev]

To add to what hsmith said - re-running the "fullinstall" script after creating a "installed.firewall" file should fix the issue. The problem was that for some reason the latest Linux agent installer was not pushed out. There was a missing code in the 4-firewall file:

if [ $ver -eq 7 ]; then
if ! hash firewall-cmd 2>/dev/null; then
skip_firewall
fi
firewall-cmd --zone=public --add-port=5666/tcp --permanent
firewall-cmd --zone=public --add-port=5667/tcp --permanent
firewall-cmd --reload
systemctl restart firewalld
else
service iptables restart
fi

which, I believe, caused the problem. Let us know if you have any more questions/issues.

Thanks that did the trick. Have a nice day.
