ModPerlEngineContrib causing Apache startup problems

Hi,

We have two foswiki-installations. Call them foswiki-test and foswiki-productive.
Both are running Foswiki-1.0.6, Sun, 21 Jun 2009, build 4272.
Operating System is Ubuntu 8.04 LTS.
Both systems are quite similar, but not identical.
Trying to speed up foswiki I installed ModPerlEngineContrib, first in foswiki-test.
Installation via apt-get install didn't work, see http://foswiki.org/Tasks/Item8146.
So I had to install the contrib manually, using the attached apache.conf.
This configuration was derived from foswiki-productive.
On foswiki-test ModPerlEngineContrib is working.
On foswiki-productive the "speed-up" foswiki doesn't start, giving this message in apaches error.log (see attachment foswiki-errors.txt):
Foswiki has been configured and "LocalSite.cfg" is available.

Any suggestions?

Thanks

Ron Beezer

Hi Ron,

According to your error.log, the problem is with the /var/lib/foswiki/tools/mod_perl_startup.pl file. Check if it exists on foswiki-productive and if the Foswiki install path is the same as foswiki-test. Check also if the webserver user has permission to read such file.

Hi Gilmar,

I made the checks:

• The file /var/lib/foswiki/tools/mod_perl_startup.pl exists on foswiki-productive
• The apache user www-data:www-data has permission to read the file
• The Foswiki install path is the same as in foswiki-test (/var/lib/foswiki)

I built two apache.conf files using the ApacheConfigGenerator

• The CGI-variant works.
• The mod_perl variant gives the error messages already reported.

Additionally I transferred the LocalSite.cfg from foswiki-test to foswiki-productive. No postive effect.

Then I replaced /var/lib/foswiki/tools/mod_perl_startup.pl (from ModPerlEngineContrib.zip) with the version from the debian foswiki package :

#!/usr/bin/perl

$ENV{MOD_PERL} =~ /mod_perl/ or die "mod_perl_startup called, but mod_perl not used!";
use lib qw( /usr/lib/cgi-bin/foswiki );
require 'setlib.cfg';
1;

Then Apache starts, giving this message in the error.log:

[Fri Aug 14 12:59:58 2009] [notice] Apache/2.2.8 (Ubuntu) mod_apreq2-20051231/2.6.0 mod_perl/2.0.3 Perl/v5.8.8 configured -- resuming normal operations
 

Does this mean that Foswiki is working in the desired mode using mod_perl?

Note: installation of foswiki-modperlenginecontrib using apt stops at file /var/lib/foswiki/tools/mod_perl_startup.pl, giving an error message, that this file is also part of the package foswiki

Check permissions of LocalSite.cfg in foswiki-productive and try to run configure again. I suspect the problem is some syntax error in LocalSite.cfg or lack of permission.

According to his logs, it's working just fine. Closing this question, but it might need a follow-up in tasks because mod_perl_startup.pl should NOT be part of the default foswiki package.
