Trying mod_perl for the first time - how to enable it?

Dear all,

I am trying my mod_perl in my Apache webserver for the first time (under
Mdk-Linux).
I have created a simple "print hello world" script with the name 'hello.pl'
and I stored it under 'var/www/cgi-bin/' but whenever I try to open
the script with http://localhost/cgi-bin/hello.pl

It gives "Internal Server Error" like this: http://paste.phpfi.com/48050.

BTW my httpd.conf is like this: http://paste.phpfi.com/48067
and my httpd2.perl.conf is like this: http://paste.phpfi.com/48068

Can anybody suggest what's wrong with my approach?
Thanks a lot beforehand.

I am not sure. How can I check that?
I just simply write a perl code like normal where you can execute
under command line like this: $ perl test.pl

with _"print 'hello\n";_ in it
And just the code under /var/www/cgi-bin

Should I change
my httpd.conf here: http://paste.phpfi.com/48067

OR

my httpd2.perl.conf here: http://paste.phpfi.com/48068

Hope to hear from you again.

You should check out
http://perl.apache.org/docs/2.0/user/intro/start_fast.html
which gives you a quick guide to configuring and testing
mod_perl, both with a simple registry script and with a
simple response handler.

Looks like you didn't tell http.conf where your .pl scripts are.
My httpd.conf includes a :
##Mod_Perl stuff

Alias /perl/ /var/www/perl/
<Location /perl/>
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
PerlOptions +ParseHeaders
Options +ExecCGI
</Location>

Hopefully, you have had a chance to look at some of the documentation
that others have suggested. Also, CGI scripts have to have a special
output format. They need to include headers telling the server/browser
what to do with the output. Your best bet is to follow the
documentation step-by-step to make sure that the server is doing what
you think before writing your own scripts.

As for your error_log/config files, it appears that you do need to tell
your server where your cgi-bin is, as noted elsewhere. Also, you need
to change permissions and chmod on all your scripts so they can be run
by the server. Those "permission denied" errors often imply a script
that does not have correct access and execute privileges set.
