startup.pl confusion
I have enabled mod_perl for apache2, and that appears
to be working fine. Now I need to get a mod_perl
module called Interchange::Link running. It is
supposed to let me access my pages like this:
mydomain.com/sample.html
instead of this:
mydomain.com/cgi-bin/catalog/sample.html
Since the former still doesn't work, I don't think the
module is loading properly. I think where I'm stuck
is the startup.pl file that is supposed to tell the
system where the Interchange::Link.pm file is. I have
the file in /usr/lib/perl5/site_perl/5.8.2/startup.pl
and it contains:
use lib qw(/usr/lib/perl5/site_perl/5.8.2);1;
which seems kind of redundant to me, but it seems to
be what the brief Interchange::Link README file asks
for. I then have the following:
/usr/lib/perl5/site_perl/5.8.2/Interchange/Link.pm
Does anyone see where I might be slipping up?

I am extremelly happy to report that I now have this
working. I found an important thread in the
Interchange mailing list archives. The user running
apache2 turned out to be apache, and that was set up
automatically in case anyone is interested.
I'm sorry if I've been an eyesore, but I've learned a
lot about apache and linux through getting this to
work. I won't be quite so helpless the next time.
Thanks a lot for everyone's help!

If you start it as root, then I believe it defaults to "nobody" when
User is not specified.

Not a good sign. If the authors of the software won't help you and you
can't understand their code, this may not be the best choice for you.

I can't really say, given that I don't know what the purpose of the
socket is or what Interchange::Link might use it for. This is something
you need to find out from a person familiar with Interchange.

Perrin,
My httpd.conf file is apache2.conf after being set up
by Gentoo and there doesn't seem to be any mention of
which user and group it runs as. The Link.pm file is
unreadable to me. Would it be safe to let the user in
question rwx the socket file?

Look in httpd.conf. It will say which user and group it runs as. Then
read the Interchange::Link code to find out what it's doing with the
socket (read, write, whatever). Change the permissions on the socket to
let that user do what it needs to.

Sorry to be such a newbie, but how can I find out what
user apache2 runs as and make sure that user has the
permissions it needs?

You need to check what user your apache servers runs as (probably
"nobody") and make sure that user has permissions to do whatever the
module is trying to do with that socket.

Not really a ringing endorsement... We're happy to help with mod_perl
problems, but this is sounding like a problem specific to the
Interchange code which I don't know much about.

When people hit "reply all" they get your address in the To: field and
the list in the Cc: field. There is some info on it here:

I had forgotten to check my error_log file. Sorry
about that. I have many entries in error_log like
this:
ok= defined=
sockname=/usr/local/interchange/etc/socket: Permission
denied
I have defined in my apache2.conf file:
<Location /foundation>
SetHandler perl-script
PerlResponseHandler Interchange::Link
PerlOptions +GlobalRequest
PerlSetVar InterchangeServer
/usr/local/interchange/etc/socket
</Location>
The socket file looks like this:
srw------- 1 interch users 0 Jun 28 11:35 socket
I have asked the Interchange list without any help.
IC is an awesome piece of software, but it can be very
tough to get answers out of the list.
Interchange::Link is totally brand new.

This is everything the Interchange::Link README file
says about installation:
INSTALLATION
You must specify that Apache use mod_perl, and you
must tell it where to
find the Perl modules you want to use.
On a Red Hat Linux system you might copy this file
to
/usr/lib/httpd/perl/ via this procedure:
mkdir -p /usr/lib/httpd/perl/Interchange
cp Link.pm /usr/lib/httpd/perl/Interchange
Then you provide a startup script that tells
mod_perl where its
libraries are:
cd /usr/lib/httpd/perl
echo "use lib qw(/usr/lib/httpd/perl);1;" >
startup.pl
Then you can put in your
/etc/httpd/conf/httpd.conf:
PerlModule Apache2
PerlRequire /usr/lib/httpd/perl/startup.pl
Finally, you specify a location like:
<Location /foundation>
SetHandler perl-script
PerlResponseHandler Interchange::Link
PerlOptions +GlobalRequest
PerlSetVar InterchangeServer
/var/run/interchange/socket
PerlSetVar OrdinaryFileList
"/foundation/images/ /foundation/dl/"
</Location>

P.S. I'm getting 2-3 copies of some messages on this
list, and they seem to be written to me with a CC to
the list. Is this configurable? It is difficult to
reply properly this way.

What makes you think this? Do you have error messages? You're not
giving us much to go on. Have you asked the Interchange developers who
wrote the module about this?
