I try to install open social using drush-8.3.0 and drupal-8.7.5. The first step is to run composer create-project goalgorilla/social_template:dev-master public_html/peer/opensocial --no-interaction. that works fine. The next step is drush -y site-install social --db-url=mysql://root:root@db:3306/social and results in the following error:

Drush\Sql\SqlException: Unable to find a matching SQL Class. Drush cannot find your database connection details. in phar:///home/username/bin/drush/drush/commands/sql/sql.drush.inc:554

Using MySQL Wizerd and MySQL admin I have created the social database and defined username, password and ip address in drush -y site-install social --db-url=mysql db_username db_password://root:root@IP address:3306/social.

I have no ida how to find out what is realy going on? I am on a linux shared server. Can anybody help? Here is stack trace:

when I run drush @hpc.dev sql-conf I get this:

First of all, you should really use Drush 9 or 10 - see https://docs.drush.org/en/master/install/#drupal-compatibility And install Drush site locally as described on the same page.

However, the message Unable to find a matching SQL Class probably means that shared server you are running Drush on is missing the needed PHP database extensions. This is typically PDO with MySQL (pdo_mysql and mysqli) - see https://www.drupal.org/docs/8/system-requirements/php-requirements#database

A typically problem is that PHP in the web server has these extensions, but not PHP on the command line.
