ubuntu 10.04 mod_perl apache registry starter?

iaw4 has asked for the wisdom of the Perl Monks concerning the following question:

Dear Perl Monks:

I have a simple CGI perl script, which I want to convert into a mod_perl script for faster speed under ubuntu 10.04 (presumably, among the most popular distributions). that's it. reading around the web, I probably want something simple, like Apache::Registry. (Not sure why it is simple...just read it was.)

Does anyone know of a good primer? I started with

 apt-get install libapache2-mod-perl2 libapache2-mod-perl2-dev libapac
+he2-mod-perl2-doc perl-doc
[download]

then installed Apache::Registry,

  # cpan
  > get Apache::Registry
[download]

then added inside my VirtualHost the following lines:

        Alias /perl-bin/ /usr/local/perl-bin/
        <Location /perl-bin>
             SetHandler perl-script
             PerlHandler Apache::Registry
             PerlSendHeader On
             Options ExecCGI
        </Location>
[download]

and I mkdir'ed /usr/local/bin/perl-bin/ . alas, even after a restart of the apache2 server, I get

# apache2ctl -l
Compiled in modules:
  core.c
  mod_log_config.c
  mod_logio.c
  prefork.c
  http_core.c
  mod_so.c
[download]

so, no mod_perl that I can see so far. what I have done sofar is all guesswork, of course. I need a step-by-step guide. I did not find one with google. has anyone written such a thing?

Advice, as always, appreciated.

To show all loaded modules use: `apache2ctl -M` If `perl_module` has not been loaded, add the following line to your `httpd.conf` and restart Apache: `LoadModule perl_module modules/mod_perl.so` Documentation, tutorials, etc. can be found on http://perl.apache.org/.	[reply] [d/l] [select]

thank you, gentlemen. I did not know about fastcgi, but this was very easy to get going, so I am using fastcgi now.	[reply]

There are numerous documents out there about mod_perl, and other technologies such as FastCGI. Probably even a cookbook. However, I would observe that “good ol’ CGI” can go a long way when used with a well-tuned server and a judicious mix of dynamic vs. static (cached...) content. The transition from this environment to other alternatives is not quite a non-trivial task. I suggest that you consider your existing application very carefully before concluding that it “must” be converted to another form of deployment. It ain’t necessarily so...
