A working Apache2 server with PHP7.4

I was in need of a server solution that could be quickly deployed as a VM.

      1. Install Debian 11 as a VM with web- and SSH server
      2. Create a USER next to your root account during the installation
      3. Find the IP address of the new installation. The easiest is if you have NoVNC running. Log in as USER and type 
        ip a
      4. Time to so the sudo thing 
        su

        log in as root

        apt-get update && apt-get install -y sudo
        usermod -aG sudo USER
        exit
        exit

        log back in as USER

      5. Okay, let’s install some more stuff but first we do an update 
        sudo apt-get update && sudo apt-get upgrade -y

        Now we want some essentials

        sudo apt-get install -y dirmngr gnupg2 nano wget gpg curl fail2ban ufw software-properties-common

        Preparing the PHP install

        wget -q https://packages.sury.org/php/apt.gpg -O- | sudo apt-key add -
        echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php.list
        sudo apt-get update
        sudo apt-get install -y php7.4 libapache2-mod-php7.4 php7.4-mysql php7.4-curl php7.4-gd php7.4-mbstring php7.4-xml php7.4-xmlrpc php7.4-zip

        And restart the Apache2 Webserver

        sudo systemctl restart apache2
      6. Alright, that’s done. Next step is to test things. 
        sudo nano /var/www/html/test.php

        Enter this into the php file and press Control X and type Y to save and exit.

        <?php
// Show all PHP information
phpinfo();
?>
      7. Go to the IP address of the server you just created and type 
        HTTP://IP ADDRESS/test.php

        If you see a PHP page with all sorts of data, you’re good. If not, go fix. Don’t ask me, I’m not there yet!

Arguments:
  user_id               will rescan all files of the given user(s)

Options:
  --path                limit rescan to the user/path given
  --all                 will rescan all files of all known users
  --quiet               suppress any output
  --verbose             files and directories being processed are shown
                        additionally during scanning
  --unscanned           scan only previously unscanned files
