From the project:

  mod_perl brings together the full power of the Perl programming language and the Apache HTTP Server. You can use Perl to manage Apache, respond to requests for web pages and much more.

## Installation

Install the mod_perlAUR package.

## Configuration

Load the module via the main Apache configuration file:

    httpd.conf

    LoadModule perl_module modules/mod_perl.so

### Allow perl to execute scripts for certain directories

There are two possible methods to enable the `mod_perl` module:

- #Using virtual hosts, or
- #For a subdirectory.

#### Using virtual hosts

Add a virtual host with settings. For example:

    /etc/httpd/conf/extra/httpd-vhosts.conf

    <VirtualHost perlwebtest:80>
    	Servername perlwebtest
    	DocumentRoot /srv/http/perlwebtest
    	ErrorLog /var/log/httpd/perlwebtest-error.log
    	CustomLog /var/log/httpd/perlwebtest-access.log combined
    	<Directory /srv/http/perlwebtest>
    		AddHandler perl-script .pl
    		PerlResponseHandler ModPerl::Registry
    		Options +ExecCGI
    		PerlOptions +ParseHeaders
    		AllowOverride All
    		Order allow,deny
    		Allow from all
    	</Directory>
    </VirtualHost>

Ensure `/etc/httpd/conf/httpd.conf` includes the created virtual host:

    Include conf/extra/httpd-vhosts.conf

Make sure it does not have `Options Indexes FollowSymLinks`!

Add "perlwebtest" as localhost in `/etc/hosts`, using the machine's hostname for `yourhostname`:

    127.0.0.1	localhost yourhostname perlwebtest

#### For a subdirectory

Add the following to the main configuration file:

    /etc/httpd/conf/httpd.conf

    Alias /perlwebtest/ /srv/http/perlwebtest/
    <Location /perlwebtest/>
          AddHandler perl-script .pl
          AddHandler perl-script .cgi
          PerlResponseHandler ModPerl::Registry
          PerlOptions +ParseHeaders
          Options +ExecCGI
          Order allow,deny
          Allow from all
    </Location>

### Turn on perl for directory listings

Create `/etc/httpd/conf/extra/perl_module.conf` as well:

    /etc/httpd/conf/extra/perl_module.conf

    # Required modules: dir_module, perl_module

    <IfModule dir_module>
            <IfModule perl_module>
                    DirectoryIndex index.pl index.html
            </IfModule>
    </IfModule>

Then include it in `/etc/httpd/conf/httpd.conf`:

    /etc/httpd/conf/httpd.conf

    # Perl
    Include conf/extra/perl_module.conf

### Try it out

Create `index.pl` in `/srv/http/perlwebtest`:

    #!/usr/bin/perl
    print "Content-type: text/plain\n\n";
    print "mod_perl now works\n";

Restart Apache's `httpd.service` and let it reload the configuration.

Finally, depending on chosen alternative configuration, visit

- http://perlwebtest for #Using virtual hosts, or
- http://localhost/perlwebtest for #For a subdirectory.
