Fedora 15: Nagios errors
Installation of Nagios on Fedora 15 is easy as yum install nagios nagios-plugins* php nrpe. I only found one problem: Error: Could not read object configuration data!
The webserver runs as user apache, which cannot access /etc/nagios/objects by default. Chmod or chown the directory to fix it, or add user apache to the group nagios.
You may also want to check the selinux settings, which can be restored by typing restorecon /etc/nagios© GeekLabInfo

Thanks. I solved in 1 min what 10 hours work didn't solve.
The official Nagios documentation should contain this detail. Excellent! Thank you!
Took me hours to figure out, thanks!
Thank's a lot it works fine now ... after 2 days searching in Google...
