Installing Drupal

I know it has been asked dozens of time, but after reading previous posts I am still unsure.  I just installed Drupal 10 and everything looks great with the exception of this error in Drupal status:

"Trusted Host Settings
Not enabled
The trusted_host_patterns setting is not configured in settings.php."

I just launched my first blog post at sysopsguide.com/drupal-ha.

If you're wondering how to setup Drupal 10 with high availability in AWS then definitely check it out. This step by step guide details the entire process, with linux commands you can copy and paste as well as screen shots that illustrate what to do in the AWS console.

If you're a Drupal expert then please take a look and let me know if there is anything that can be improved to make the article more accurate or less confusing.

Thanks! 

I'm new to Drupal and have a lot to learn.  I installed Drupal 10.0.9 on Ubuntu 20.04 and would like to use drush. However, after going through a few steps, I am stuck with the following error:

"Root package 'drush/drush' cannot require itself in its composer.json"

Here are the commands I ran in the process:

sudo curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

sudo composer global require drush/drush:dev-master --with-all-dependencies

I am trying to install Drupal in a shared cluster, where the cluster shares a base url (eg https://xyz.com) and the Drupal app is accessed via https://xyz.com/drupal

However, the CSS and JS files are all operating off a relative path (ie. "<script src='core/themes/claro/css/components/node.css?0'>")

I'm trying to restore an old website, that runs drupal 7.58, but i'm getting a ton of deprecated function erros.

How do i start fixing this?

Thanks.

I have some backup files of an old drupal website.

There are some .sql files as well as a full backup .tar.gz file.

How do i restore the site and run it locally with xampp?

I have tried installing drupal, i get the initial site after installation but i cannot figure out how to take my backup and make it live.

I would very much appreciate a response.
