Cannot get moodle to install on my remote server/virtual machine

I'm playing with a free MS Azure account, and am trying to upload an open-source LMS (Learning Management System) called Moodle onto it. I've set up the virtual machine/SSH, am in the server via Windows Terminal, and have installed LAMP. I've installed Apache2, mySQL and PHP & PHP (cli version).

This is my first real play with PHP. I've managed to get the public IP to display the Apache2 Ubuntu default page (index.html inside /var/www/html/).

I've been following this moodle installation guide and am stuck at the 'Install Moodle' part. I've got/decompressed moodle successfully, created the database etc. I've used ls and dir -a commands to confirm the file (I think) I need to execute is at /moodle/admin/cli/install.php but when I try to run the php install script, all I get is 'Could not open input file: path to file here'

I've tried a few variations as below:

/usr/bin/php /moodle/admin/cli/install.php /usr/bin/php7.4 /moodle/admin/cli/install.php

I think I'm literally at the last hurdle! Any ideas, anyone? Also, once that's done, how would I redirect the launch page from the default ubuntu index.html to the moodle startup page, or would that be automatic (following successful install?)

It's a linux/ubuntu 20.04 server.

Thanks so much kind soul.
