Drupal 8.x

in an effort to personally compare drupal vs wordpress, i downloaded it to my windows 10 machine.
extracted the drupal folder to c:\xampp\apps (same location as WP).

now what?

I need help to create other contents by author block. I googled and search around, but I still can't find the result. How to create a view block to display other contents by author in one of the content page created by the author to visitors in Drupal 8.

I found here a contextual filter call "User ID from URL" in Drupal 7, but it's gone in 8. I knew how to create related contents view block for current user, but no for visitors.

Thanks in advance

My company have a old Client/Server management system, drivered by postgresql with huge data(the database named database1,...databaseN.).I want to rebuild a new Brower/Server system with Drupal8. My Question is, 1.when I install drupal8 with postgresql(the database named drupal8 database) , should I migrate the old Database1,...,databaseN into drupal8 database, or use two or more database in my new B/S drupal8 system?
2.if I use two or more database in drupal8 system, how about the efficiency of drupal8 connecting and disconnecting the Database1,...,databaseN ?

Is there a SaltStack .sls file, Puppet manifest, or Ansible play-book to install Drupal? I'm interested in full installations without using the web-based configuration tool. Is it possible to not use the GUI and install Drupal?

I am using CentOS 7. I have installed MariaDB 5.5 and Apache 2.4.6. I tried to install Drupal 8.0.5. It seems like it was installed correctly. I followed some directions on DigitalOcean's website. The problem is that the web-based Drupal page is not there. I open a web browser and type in the IP address of the CentOS server. I see "Testing 123." This is the generic Apache page. The Apache service is up and running. I reinstalled Drupal. I get the same problem. What did I do wrong?

Hi!

I just installed drupal 8 on 1and1.

I have PHP7 installed and MySQL 5.5.

The installation went smooth, but I only get a weird all-text page instead of something nice... or else I get a 500 error...

What can I be doing wrong?

Thanks!
