I've used Perl off and on for years but I am now trying to work with
mod_perl and I have some questions/issues.
How can I tell if I have mod_perl configured correctly? I installed
it with `emerge mod_perl` on my Gentoo box. I am running Apache2. I
see the line:
Apache/2.0.52 (Gentoo/Linux) mod_perl/1.99_11 Perl/v5.8.5 PHP/5.0.3
Server at destiney.mine.nu Port 80
when I type a nonexistant url. Is that it as far a "complete" mod_perl install?
My apache config contains this:
<IfModule mod_perl.c>
#Provide two aliases to the same cgi-bin directory,
#to see the effects of the 2 different mod_perl modes
#for Apache::Registry Mode
Alias /perl/ /var/www/localhost/perl/
#for Apache::Perlrun Mode
Alias /cgi-perl/ /var/www/localhost/perl/
</IfModule>
<IfModule mod_perl.c>
PerlModule Apache2::ModPerl::Registry
#set Apache::Registry Mode for /perl Alias
# To set subdirectories to use perl set the following
# and comment the orignial:
# <Location ~ "^/perl/.*\.pl$">
<Location "^/perl/*.pl>
SetHandler perl-script
<IfDefine MODPERL2>
PerlResponseHandler Apache2::ModPerl::Registry
</IfDefine>
<IfDefine !MODPERL2>
PerlResponseHandler ModPerl::Registry
</IfDefine>
Options -Indexes ExecCGI
PerlSendHeader On
</Location>
#set Apache::PerlRun Mode for /cgi-perl Alias
<Location /cgi-perl/*.pl>
SetHandler perl-script
PerlResponseHandler ModPerl::PerlRun
Options -Indexes ExecCGI
PerlSendHeader On
</Location>
</IfModule>
So does that mean when I put a .pl script in /perl/ it will be
executed by mod_perl and not #!/usr/bin/perl? Seems to not be the
case since when I remove the #!/usr/bin/perl from the top of a script
it breaks it and I get error like:
[Sat Dec 18 14:43:31 2004] [error] [client 10.0.0.3] (8)Exec format
error: exec of '/var/www/localhost/perl/hello.pl' failed
[Sat Dec 18 14:43:31 2004] [error] [client 10.0.0.3] Premature end of
script headers: hello.pl
in my logs. I read somewhere in the docs when using mod_perl that the
#!/usr/bin/perl is no longer required, so I'm thinking maybe I'm not
done with the apache configuration?
What is the advantage to running mod_perl versus just running perl
scripts out of my cgi-bin ? I suspect there is a performance gain
from to the interpreter already existing in memory or something, but
is there some new syntax I get to use now? Can I now include Perl
code directly into my html?
Thanks for any help you send..
