Drupal 8.x

I'm trying to follow the Multisites directions but I'm totally lost. I get either a 404 error, "Drupal already installed", or I get the main sites home page.

I would like each of the multisites to have it's own url, but the same code base. So it would be user1.mysite.com, user2.mysite.com, user3.mysite.com but nothing seems to be working. If someone could point out me the magic pixie dust that I'm missing to get this working, I'd really appreciate it.

This what is in my sites.php

Hello,

Just read the latest announcement about some investors piling cash into Acquia for some shares, so they can hit it big if Acquia goes public (http://buytaert.net/acquia-raises-50-million-series-f).

I need to have a design made for my company site which is running Drupal.

PM me if you can do it, I will pay.

Thanks

Alright, what I'm trying to do is mostly for ease of access but ease of access is a major pushing point for the site so I'd really like to find a way to make it work. Basically I have a custom content type called Teacher for the site I'm working on, and this Teacher content has an autocomplete field for Classes Taught as a required field. The Classes Taught field is used to filter and sort out the teachers based upon which classes they're teaching, for example having a page which only has Fifth grade teachers, or only 6th Grade math teachers, etc.

Hey everybody,
