[oclug] RedHat, Apache and Mod Perl

Sun Jul 13 19:48:12 EDT 2003

OK.... here is the deal.. A friend is trying to get mod_perl going on a
RedHat server. Apache 2.0.47 from RPMs at RedHat. mod_perl from same.

Here is the failure mode:

Server error!
The server encountered an internal error and was unable to complete your
request.
Error message:
Can't locate object method "request" via package "Apache" at
/usr/lib/perl5/5.8.0/CGI.pm line 269.
If you think this is a server error, please contact the webmaster
Error 500
localhost

Apache/2.0.40 (Red Hat Linux)

here is the script:

[root at purple wfenwick]# cd /var/www/perl[root at purple perl]# more
test2#!/usr/bin/perl
use CGI qw(:standard);#use CGI;
my $query = new CGI;
print $query->header;
print "<html>\n";print "<head><title>CGI Results</title></head>\n";print
"<body bgcolor=\"#FFFFFF\">\n";
if ($query->param("search")) {        $search = $query->param("search");
        open(DATA,"DATA.TXT") || print "Open Error: $!\n";        while
(<DATA>) {                if (/${search}/i) {
$customers++;                }        }        print "We have $customers
customers ";        print "whose names contain
n";                } else {        print "<form method=GET
action=",$ENV{"SCRIPT_NAME"},">\n";        print "<input name=search size=10
value=\"r\">\n";        print "<input type=submit>\n";        print
"</form>\n";}
print "</body></html>\n";
here is the config for mod_perl:

[root at purple perl]# cd /etc/httpd/conf.d[root at purple conf.d]# lsperl.conf
README  ssl.conf  ssl.orig[root at purple conf.d]# more perl.conf## Mod_perl
incorporates a Perl interpreter into the Apache web server,# so that the
Apache web server can directly execute Perl code.# Mod_perl links the Perl
runtime library into the Apache web server# and provides an object-oriented
Perl interface for Apache's C# language API.  The end result is a quicker
CGI script turnaround# process, since no external Perl interpreter has to be
started.#
LoadModule perl_module modules/mod_perl.so
# This will allow execution of mod_perl to compile your scripts to#
subroutines which it will execute directly, avoiding the costly# compile
process for most requests.#Alias /perl /var/www/perl<Directory
/var/www/perl>    SetHandler perl-script    PerlHandler
ModPerl::Registry::handler    PerlOptions +ParseHeaders    Options
+ExecCGI</Directory>

I tried upgrading the CGI.pm and associated files to the latest, but with no
better result. Also a simpler script seems to work just fine...

[root at purple perl]# more test.pl#!/usr/bin/perlprint "Content-type:
text/plain\n\n";print "mod_perl rules!\n";
Any ideas or pointers...?
