Topic: [Solved] Apache 2.4 with CGI / perl does not execute cgi

[bouncybomb]

CLOSED

Hello Apache Lounge community,

I am trying to set up gitweb for my firm, but cgiweb.cgi is not executed and is instead returned. This is Apache 2.4 on Ubuntu LTS.

I have a2enmod'd cgid and restarted. The load is in the mod-enabled dir.

I have apt-get install'd libapache2-mod-perl2 and restarted. The load is in the mod-enabled dir.

Applying log level trace8 on my site conf I get this in the logs:

Which seems to indicate that mod-cgid is never triggered and I have no idea why.

I see /usr/lib/cgi-bin is valid and has +ExecCGI in serve-cgi-bin.conf

Any help would be much appreciated.
Cheers.


[/b]Update:

I've adjusted the paths in my site conf so that the SciptAlias is used instead of the absolute path for cgi-bin, and I get errors from mod_deflate but same result:

And another update, using the url http://git/cgi-bin/gitweb.cgi does execute the cgi script and i get the results I want, so my site conf must be wrong?

This is the content:
