De-activate SELinux

For now, Adagios on SELinux enabled machines does not work.

setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

Install nagios

sudo yum install nagios

pynag

Right now the fedora version does not contain the version needed, so we install from git clone

Install

git clone git://github.com/pynag/pynag.git
cd pynag
sudo ./setup.py install

Test

$ pynag list where object_type=service
object_type          shortname            filename
