Perl .pl file downloads instead of being executed

Question

I'm trying to get OTRS 4.0 working on Ubuntu 14.04. I've followed all instructions to install from source.

When I open the site (localhost/otrs/index.pl), an empty .pl-file is served for download. Apparently Apache finds the index.pl, but does not know what to do with it.

• OTRS is installed with all relevant perl modules (checked by install script)
• Vhost is copied from scripts folder in OTRS
• hosts is updated for the local test domain
• Apache is restarted

Modules

cgi.load -> ../mods-available/cgi.load
perl.load -> ../mods-available/perl.load

Question

How can I get Perl working with Apache?

Solution 1

Make sure you have set the following path in your /etc/apache2/apache2.conf:
ScriptAlias /cgi-bin/ "/path/to/cgi-bin/" and that your scripts are in that folder.

If your scripts ends on .pl make sure to change the line
AddHandler cgi-script .cgi to AddHandler cgi-script .cgi .pl
in /etc/apache2/apache2.conf and check that it is not commented out.

Options FollowSymLinks +ExecCGI needs to set in your virtual host.

Solution 2

Waking the dead but with the answer. Do this:

ln -s /etc/apache2/mods-available/cgid.load /etc/apache2/mods-enabled/
ln -s /etc/apache2/mods-available/cgid.conf /etc/apache2/mods-enabled/

sudo service apache2 restart

and it works.

Thanks for the reply! There was no AddHandler in apache2.conf. I've added it. There was no ScriptAlias either. OTRS has its own ScriptAlias for cgi-bin: ScriptAlias /otrs/ "/opt/otrs/bin/cgi-bin/". So this alias should point to the OTRS cgi-bin? Adding the cgi-bin ScriptAlias doesn't change anything after a restart.

I just had a chance to take a more detailed look at OTRS. All necessary config is allready provided in the /opt/otrs/scripts/apache2-httpd.include.conf. Have you copied that file to your /etc/apache2/conf-available directory and enabled it with a2ensite apache2-httpd.include?

Or a2enmod cgid
