Apache can't connect CGI files.

[MartonT88]

Hello,

I installed the latest version of Nagios Core 4.4.14. The Nagios itself is running, The apace and php-fpm service also running. The site loading properly, but all of the options shows the following error messages:

Unable to get process status

Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

The httpd error log shows the following for all CGIs.

Do you have any other hints to solve this problem?

Thank you in advance.

Solution:

/etc/httpd/conf.modules.d/00-mpm.conf

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

Line need to be enabled to remove the #, and the other Load module need to be commented out.
