Re: [EP-tech] Apache and PerlSwitches

Hi Matt,


This is a bit of a mystery.  Did you run generate_apacheconf to generate new Apache configuration files like the one that has the syntax error you reported or did you just copy this from the older server.  If the latter, run the following command (as the eprints user) to make sure you have Apache configuration appropriate for your current environment:


/opt/eprints3/bin/generate_apacheconf --system --replace


It may be that something other than this line is causing the issue but due to a syntax issue it is reporting this line as a problem rather than the one that is actually at fault.

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.
