Let's see the httpd error log again, I don't see what could be causing these 500 errors

[rtsupport]

Have attached all logs for your reference ..

Also when we are accessing localhost homepage we are able to access it but when we click on "Access Nagios XI" we are getting 500 error page as shared before.

thought to update you! in existing environment we have gearmand service running to offload the checks load is that cause any issue while restoring backup ?

[scottwilkerson]

Please run the following

Code: Select all

service postgresql start
systemctl start mariadb
systemctl enable mariadb

done, but still 500 error page while accessing web page. http://serverip/nagiosxi/

and just to update you on another server i am able to install the Nagios XI 2014 R2.7

so now we have two VM's
1-
RHEL 7.4 having 5.4.13 ( on which currently we are working upon)
2-
RHEL 7.4 having 2014 R2.7 (older version we are running in live environment)

As this thread is going too long and still we are not able to identify what we are missing, can we do remote session where you can directly work and troubleshoot if needed. keeping both VM as per requirement.

[scottwilkerson]

As this thread is going too long and still we are not able to identify what we are missing, can we do remote session where you can directly work and troubleshoot if needed. keeping both VM as per requirement.

I think this is an excellent idea as I agree the thread is long and getting hard to work with, can you please open a support ticket at
https://support.nagios.com/tickets/

Reference this thread and we will close the thread and can setup a support session.

[tmcdonald]

Closing the thread as we have a ticket open.
