[EP-tech] Apache and PerlSwitches



Hi Matt,


It is possible the module is installed but not loaded.? You can check by 
running one of the following commands:


RedHat/CentOS/Fedora: httpd -M

Debian/Ubuntu: source /etc/apache2/envvars && apache2 -M


You should see perl_module in the list returned.? My general experience 
is that Mod Perl is enabled automatically on RedHat-based Linux OS but 
often you need to run "a2enmod perl" on Debian based systems.? On RedHat 
based systems there should be the file 
/etc/httpd/conf.modules.d/02-perl.conf that loads Mod Perl. On 
Debian-based systems there should be a symlinked file in 
/etc/apache2/mods-enabled/ called perl.load that symlinks to 
/etc/apache2/mods-available/perl.load.


Regards


David Newman
