=head1 NAME

Apache2::ASP::Manual::Installation::Linux - Installation instructions for Linux

=head1 DESCRIPTION

This document describes how to install Apache2::ASP on Linux.

=head1 PREREQUISITES

=head2 Step 1: Install Apache HTTPD v2.0 or newer

Fedora Core 6 and RHEL4+ both come with Apache2.  

You will also need to install the devel libraries.  Specifically, you will need 
the executable C<apxs>, because it is required to compile mod_perl2 and libapreq2.

=head2 Step 2: Install mod_perl2

Available at L<http://perl.apache.org/>.  Because of the strange environment requirements
of mod_perl2's test suite, installation via CPAN is discouraged.

Instead of installing via CPAN, simply download the latest stable tar.gz archive, extract it
and install it like any other Perl module.

The only catch is that you can only C<make test> as a non-root user.  Then switch back to root
so you can C<make install>.

=head2 Step 3: Install libapreq2

Available at L<http://httpd.apache.org/apreq/>.

Running C<make test> may also require running as a non-root user.

=head1 INSTALLATION

Once you've installed the prerequisites (see above) you are all set to install Apache2::ASP.

Unfortunately the regular CPAN install won't work.  Again, the test suite cannot be run as root
unless the C<nobody> user can write to the C<t/> directory.

Simply download the latest tar.gz file from CPAN and run the following commands:

  % tar -zxvf Apache2-ASP-1.xx.tar.gz
  % cd Apache2-ASP-1.xx
  % perl Makefile.PL
  % make
  % make test
  % make install

Now, when you run the command:

  % perl -MApache2::ASP -e 'print "Hello, World!\n"'

You should see:

  Hello, World!

If instead you see something like:

  Can't locate Apache2/ASP.pm in @INC (@INC contains: /usr/lib/perl5/5.8.3/i386-linux-thread-multi
  /usr/lib/perl5/5.8.3 /usr/lib/perl5/site_perl/5.8.3/i386-linux-thread-multi /usr/lib/perl5/site_

  dor_perl .).
  BEGIN failed--compilation aborted.

Then Apache2::ASP was not successfully installed.  Repeat the installation process again, but this
time, B<pay attention>!.

Installing Apache2::ASP is only part of the deal.  You also need to configure a website to run on it.

=head1 DIRECTORY STRUCTURE

Assuming your server root is C</var/www> and your C<DocumentRoot> is C</var/www/html> then your directory
structure would look like this:

  /var/www
  |
  +-/html
  | `- index.asp (All ASP scripts go here, along with images, css, javascript, etc.)
  |
  +-/handlers
  | +- MyHandler.pm    (Accessible as http://yoursite.com/handlers/MyHandler)
  | `- OtherHandler.pm (Accessible as http://yoursite.com/handlers/OtherHandler)
  |
  +-/conf
  | +- httpd.conf  (to be included by /etc/httpd/conf/httpd.conf)
  | `- apache2-asp-config.xml
  |
  +-/lib
  | `- Your application classes go here (i.e. Class::DBI or DBIx::Class modules)
  |
  +-/MEDIA
  | `- (Apache must have read/write permissions for this directory)
  |
  +-/PAGE_CACHE
  | `- (Apache must have read/write permissions for this directory)
  |
  +-/t
    `- (your test files will go here)

=head2 /conf

The C</conf> directory should contain only configuration files.

Specifically, it should contain the L<Apache2::ASP::Manual::ConfigXML|XML Config File> 
and the L<Apache2::ASP::Manual::HttpdConf|httpd.conf> file.

=head2 /handlers

Your Handlers go here.  All of them.

Learn more about what Handlers are by reading the following pages:

=over 4

=item Start with L<Apache2::ASP::Manual::Handlers>

=item L<Apache2::ASP::Handler>

=item L<Apache2::ASP::UploadHandler>

=item L<Apache2::ASP::FormHandler>

=item L<Apache2::ASP::MediaManager>

=back

=head2 /html

All of your ASP scripts, images, CSS, JavaScript, SWF, PDF and other files go here, 
just like a regular website.

In addition to your ASP scripts you can also place your C<GlobalASA.pm> file in this 
directory.

Learn more about the C<GlobalASA.pm> file by reading L<Apache2::ASP::GlobalASA> and
L<Apache2::ASP::Manual::GlobalASA>.

=head2 /MEDIA

This is where uploaded files are stored.

B<NOTE:> Your webserver must be able to both B<read> and B<write> to this directory.

=head2 /PAGE_CACHE

This is where compiled ASP scripts are stored.

"What are compiled ASP scripts?" you ask?  When L<Apache2::ASP::PageHandler> prepares 
your ASP script for execution the first time around, it converts it from ASP markup to 
a first-class Perl module.  Learn more by reading L<Apache2::ASP::Manual::ASP_Compilation>.

=head2 /lib

Any Perl module that is not a Handler should go here.  This includes (for example) your
L<Class::DBI> or L<DBIx::Class> modules (or what have you) as well as any other custom,
non-CPAN modules that your web application requires.

This directory is automatically added to C<@INC> by L<Apache2::ASP::Config> so you don't 
have to do it yourself.

=head1 BUGS

It's possible that some bugs have found their way into this release.
