See https sites in local with Debian / Apache2

Question

I'm working on Debian Testing. I see local http sites at localhost/~myhome/... To this end I made the classic change to /etc/apache2/mods-available/php8.2.conf

To re-enable php in user directories comment the following lines
...

However I have an https site in which .htaccess I added

RewriteEngine on
RewriteCond %{HTTP_HOST} ^sito.net$ [OR]
RewriteCond %{HTTP_HOST} ^sito.it$ [OR]
RewriteCond %{HTTP_HOST} ^www.sito.it$
RewriteRule ^/?$ "http\:\/\/www\.site\.net" [R=301,L]`

and still from local I cannot see it, receiving:

Internal Server Error
The server encountered an internal error or misconfiguration
and was unable to complete your request.`
Please contact the server administrator at webmaster@localhost
to inform them of the time this error occurred, and the actions
you performed just before this error.
More information about this error may be available
in the server error log.
Apache/2.4.58 (Debian) Server at localhost Port 80`

I followed some (old) instructions found in this thread: How do I allow HTTPS for Apache on localhost?

I did the following steps:

# openssl req -x509 -newkey rsa:2048 -keyout mykey.key -out mycert.pem -days 365 -nodes
#cp mycert.pem mykey.key /etc/ssl/private/
#a2enmod ssl
#a2ensite default-ssl.conf
#systemctl restart apache2

but receiving:

root@debian:~# systemctl restart apache2
Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xeu      apache2.service" for details.

And after:

root@debian:~# systemctl status apache2.service

The line referring to that error:

I am unable to make any further attempts...

First install apt install libapache2-mod-php8.2

Dump your whole running config with apachectl -S

And when you want to make an application available to be served by apache, it's best practice to create a virtual host in /etc/apache2/sites-available

An example of a virtual host looks like this

    <VirtualHost *:80>
    ServerName yourdomain.com
    ServerAlias www.yourdomain.com

    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    RewriteEngine on
    RewriteCond %{SERVER_NAME} =yourdomain.com [OR]
    RewriteCond %{SERVER_NAME} =www.yourdomain.com
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

<VirtualHost *:443>
    ServerName yourdomain.com
    ServerAlias www.yourdomain.com

    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    SSLEngine on
    SSLCertificateFile /etc/ssl/certs/yourdomain.crt
    SSLCertificateKeyFile /etc/ssl/private/yourdomain.key
    SSLCertificateChainFile /etc/ssl/certs/yourdomain.ca-bundle

    <Directory /var/www/html>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    <FilesMatch \.php$>
        SetHandler "proxy:unix:/var/run/php/php8.2-fpm.sock|fcgi://localhost/"
    </FilesMatch>
</VirtualHost>

Then save it in /etc/apache2/sites-available/ as yoursite.conf

• Then enable the vhost sudo a2ensite yourdomain.conf
• Test your configuration sudo apachectl configtest
• If everything is ok restart apache sudo systemctl restart apache2
