Needed Apache modules for Nagios Core

[sawozny]

Greeting Nagios Gurus!

Does anyone know what Apache modules (beyond the Core and the appropriate Multi-Processing Module) are needed for Nagios Core to work properly? For example, I can see there’s a lot of CGI from the documentation, but I can’t tell if the CGI is thread safe (which would influence my choice of MPM) or if “classic” CGI (mod_cgi(d)) or Fast CGI is needed. I suppose I could install, look for errors and add / switch modules as needed, but I was hoping someone had been through this before and had a list available.

Any thoughts or suggestions would be appreciated.

Thanks,

Scott

Generally no special modules other than the defaults but this could vary by OS.

All of the prerequisites for many OSs are listed here:

Thanks for the reply. Interestingly, the purpose of the question was to see how much LESS than the defaults I could get away with (i.e. RHEL yum Apache httpd comes with a TON of stuff pre-loaded that, unless it's needed by something, could only serve to increase your attack surface and bite you in the butt) but I appreciate the link as a starting point. I'll give this some trial and error, see what I come up with and report back.

Thanks,

Scott

Sounds good. I don't know of any specific testing to the minimal modules
