Setup Drupal 9 From Terminal Using Drush

Get fresh Drupal:
composer create-project drupal/recommended-project d9.dev
Done.

Install Drush:
composer require --dev drush/drush
Done.

Make Drush global:
wget -O drush.phar https://github.com/drush-ops/drush-launcher/releases/latest/download/drush.phar
chmod +x drush.phar
sudo mv drush.phar /usr/local/bin/drush
drush --version
Done.

drush site:install standard --db-url='mysql://drupal:drupal@localhost/d9_dev' --site-name=d9_dev
Done

Now try to access your site in browser. Surely, you will notice there are no styling present. To
solve this just give appropriate directories the appropriate permissios:

chmod 777 sites/default/files
sudo systemctl reload apache2
Done.

Now, clear the cache with drush cr or otherwise and try to reload the site in browser.
Done.

Enjoy the party.
