[otrs] Another Config.pm problem

Hi

I'm new to otrs and also out-of-touch with perl. So this could be a
simple problem. I've installed latest otrs on a linux, Debian Lenny,
from source, carefully followng chap 3.2.1 of the pdf documentation.

Now wenn I call http://myserver.mydomain/otrs/installer.pl from the
browser I get an "Internal Servr Error, The server encounted an
internal error or misconfiguration and was unable to complete your
request".

The apache2 log file records "Can't locate Kernel/Config.pm in @INC
(@INC contains: ...) at /home/www/otrs/bin/cgi-bin/installer.pl line
40."

installer.pl line 40 is "use Kernel::Config;"

the section over line 40 goes
===
use strict;
use warnings;

# use ../../ as lib location
use FindBin qw($Bin);
use lib "$Bin/../..";
use lib "$Bin/../../Kernel/cpan-lib";

use vars qw($VERSION $Debug);
$VERSION = qw($Revision: 1.28 $) [1];

# check @INC for mod_perl (add lib path for "require module"!)
push( @INC, "$Bin/../..", "$Bin/../../Kernel/cpan-lib" );
===

As you must have noticed otrs is not in /opt but under /home/www.
I thought, I was careful in giving that parameter during the
installation.

Can somebody post instructions where to look?

Have you renamed /home/www/otrs/Kernel/Config.pm.dist to
/home/www/otrs/Kernel/Config.pm?

Yes, copied in fact. Content untouched.

The request http://intra.ksstadelhofen.ch/otrs/installer.pl
executes /home/www/intra/otrs/bin/cgi-bin/installer.pl
it reacts to my guess-work editing of the lines
use FindBin qw($Bin);
use lib "$Bin/../..";
use lib "$Bin/../../Kernel/cpan-lib";

but that is not a good approach ;(

In your last post the error message said "/home/www/otrs/..." no "intra"
in it.

BTW: you should chown Config.pm it makes no sense to have it owned by root

Sorry for that. I sort of annonymized the thing. Here is the
complete story:

Error message in Apache logs:

obviously @INC does not contain ./Kernel, what is the usual
procedure to add that?

Can you create a test.pl in the same directory where the index.pl is?

It should have this content:

#!/usr/bin/perl

use strict;
use warnings;
use FindBin qw($Bin);

use CGI;
print CGI->header, $Bin;

chmod it to 755, run it via Browser and post the result here.

Cheers,
Renee

Hi there

Post by Renee BÃ¤cker
Can you create a test.pl in the same directory where the index.pl is?
#!/usr/bin/perl
use strict;
use warnings;
use FindBin qw($Bin);
use CGI;
print CGI->header, $Bin;
chmod it to 755, run it via Browser and post the result here.

Same "Internal Server Error" on the browser.

'[error] Can't call method "send_cgi_header" on an undefined value at
(eval 10) line 69.\n' in the Apache logs.

Thanks a lot for the help!

I think I had an issue with mod_perl (or was it reload? ;-) some time ago with similar PATH issues.
(Actually, I have it configured under xampp, changing the path of otrs, specially for Perl is hell. Somehow in the code they have made an error to have the path not relative from where it is called)

Can you show how you're apache is configured for OTRS?

Part of mine is shown below. You can see where the extra apache-perl script is called. Do you use it as well?

/opt/lampp/etc/extra/httpd-otrs.conf:

<...>
# if mod_perl is used
<IfModule mod_perl.c>

# load all otrs modules
Perlrequire /opt/otrs/scripts/apache2-perl-startup.pl

# Apache::Reload - Reload Perl Modules when Changed on Disk
PerlModule Apache::Reload
PerlInitHandler Apache::Reload
<...>

In the startup file I have set/added the correct path. Perhaps you should too, to get it going.

/opt/otrs/scripts/apache2-perl-startup.pl:

<...>
$ENV{MOD_PERL} =~ /mod_perl/ or die "MOD_PERL not used!";

# set otrs lib path!
use lib qw(/opt/otrs /opt/otrs/Kernel /opt/otrs/Kernel/modules /opt/otrs/Kernel/
cpan-lib /opt/lampp/lib/perl5/site_perl/5.10.0/i686-linux/Apache2);

<...>
