I just stood up a virtual machine with centos 7. I installed Nagios core on it and everything completed successfully, but I am unable to access to the web portal. Please assist. I know we have allowed port 80 already.

I don't see port 80 allowed. Can you try with your firewall disabled?

So I was able to disable the firewall on the Nagios server and I am still unable to access the site.

It is working now. I had to completely stop the firewall instead of disabling it on the nagios server.

Was there anything further we can help with or are we okay to close the thread?

Please post the output of these commands:
Code: Select all
chage -l nagios
sestatus
grep nag /etc/group
grep "User \|Group " /etc/httpd/conf.d/nagios
service nagios status
ps aux |grep nagios.cfg
Try to restart the nagios service:
Then if it fails, send us the output of this command:
Code: Select all
tail -n100 /var/log/messages /usr/local/nagios/var/nagios.log
Thank you
