Installing Drupal

I'm a complete Drupal newbie trying to install Drupal 8 for the first time on a new server with Ubuntu 18.04, Apache 2.4, MariaDB 10.1 and php 7.2. I downloaded the software using composer as indicated in section 3.5 of the online User Guide.  Next,in section 3.7, it says to go to the URL I set up for the site, where I should find an installation page. When I do this, I get an index of the directory with these files and directories in it:

Hi guys

Hi guys, I really could use some help/advice. I'm trying to install the latest build on a webserver from our hosting provider. Previous drupal version (7x) was running fine. I've cleaned the database and all the folders. Installation starts and after selecting the main language I'm able to select the installation profile standard, minimum etc. After making any installation profile selection and choosing save and continue I'm back at the language selector dialog and it keeps going like that.

I have no clue whats going wrong. Thanks for any kind of advice.

All the best.

I am a first time Drupal user and am installing it (version 8) on a Windows 2016 Server using IIS. I have all the prerequisites installed and went through the Drupal installer. I entered the database info, chose 'minimal' installation, configured the site (the last step of the installer), and when it finished it gave the error, "500 internal server error".

I then reloaded the url it finished on (http://mydomain/user/1) and it loads without the 500 error.

Unable to send email. Contact the site administrator if the problem persists.

So, I was trying first time to install Multisites;

Now - I was able to set up Subdomain in sites/ subdomain to show up.....

But - the Subsite is Showing exactly the same as Default Website, and what I should do to change Databases and create a new instance?! I copied the (default)settings.php into the new sub-domain, but I cannot find an option for this?!

All examples I can find on internet - show it should bring forth installation screen, but that doesn't happen, it opens just default Website content....
