## Enabling Perl + Apache

Install mod_perlAUR.

Add this to `httpd.conf`:

    LoadModule perl_module modules/mod_perl.so

### Allow perl to execute scripts for certain directories

There are two possible methods: creating a virtual host, or enabling perl for a subdirectory.

#### Alternative 1: Using virtual hosts

Add a virtual host with various settings in 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 line

    Include conf/extra/httpd-vhosts.conf

Make sure you do not have "Options Indexes FollowSymLinks"!

Add "perlwebtest" as localhost in `/etc/hosts`:

    127.0.0.1	localhost YOURHOSTNAME perlwebtest

Use your hostname instead of `YOURHOSTNAME`.

#### Alternative 2: Just enable for a certain subdirectory

Add the following to `/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:

    # 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`:

    # 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:

    # systemctl restart httpd

Usually you can just reload:

    # systemctl reload httpd

Then visit http://perlwebtest (if you created a virtual host) or http://localhost/perlwebtest (if you only enabled one directory).
