troubleshoot if only able acess main page

setenforce 0

chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/
chcon -R -t httpd_sys_content_t /usr/local/nagios/

I might be missing something here, but what is the actual problem you are having? "troubleshoot if only able acess main page" - does that mean you can't view the main page or that you couldn't but the steps following fixed it?

Hi tmcdonald ,


This post is about steps how i installed Nagios 4.0.7 is not a problem. Hope can help some1 as reference. But is it Nagios no need to install database?

Btw, that sentence means if u only able to access main website, others showed permission error..
can follow step below to solve the problem...

Nagios does not require a database in order to work.

Thank you for the info. I am going to lock the topic because it is not a question so it is "solved" already.
