multi-site configuration

I followed this tutorial(Drupal 7) but it not worked for me(Drupal 8):

Multi-site in subdirectories https://www.drupal.org/docs/7/multisite-drupal/multi-site-in-subdirectories

My Drupal is on a Virtual Machine with only access via IP, not hostname.

This is my enviroment:

• CentOs 7 with SELinux(mode: enforcing)
• Varnish 4.0.3
• Apache 2.4.23
• Drupal 8.2.4

I need to create the next structure of sites:

• / <-- First site
• /site2 <-- Second site
• /site3 <-- Third site

In the file sites/sites.php i have:

• $sites['localhost.site2'] = 'site2';

I've been pulling my hair out trying to figure out how to solve a problem I've been experiencing with a Drupal 7 multisite installation. I've searched frantically over the last while and I was hoping that perhaps someone has solved the issue I'm having. I found some very relevant discussions and information and there does not appear to be any solution contained in them.

See the following:

• https://drupal.org/documentation/install/multi-site#symlink
• https://groups.drupal.org/node/20604
• https://groups.drupal.org/node/267198

I've recently started learning about how to setup a multi-site drupal web page.

I am working on a web site for a national veterans organization. The question has come us asking if the different states can be part of the site. The national site name would be SOA.COM. The Florida State site would be either FL.SOA.COM or SOA.COM/FL - probably the first.

At this point, I do not have a question about how to set it up, but the practicality of this approach.

I need some quick help from the group....regarding multi-site setup.

Basically I want to run a copy of an existing site, but have it use its own mailchimp form.

So here is the example. I built this site http://www.myreisystem.com and I want to create a sub-domains of this site as in
http://user1.myreisystem.com
http://user2.myreisystem.com
http://user3.myreisystem.com
etc...

Each site would have it's own mailchimp form module to act with that users mailchimp account.

We are looking into creating a secondary site that would be segregated from our principle newspaper website so that we can allow community users to create their own blogs and add comments.

The idea is that in doing so, we can better protect the newspaper's brand.

The question is though, should we do this as a Drupal multi-site configuration, as a standalone Drupal install or, for simplicity, use Wordpress instead?

The Wordpress option is based on the assumption that users are only going to be blogging, but there is a remote possibility that these functions could be extended.
