Downloading and installing with Drush

You may also install Drupal using the PHP command-line tool, Drush. Drush is a command-line tool created by the Drupal community and must be installed if you wish to use it. Drush is covered in Chapter 13, The Drupal CLI.

As of Drush 9, which supports Drupal 8.3+, this section is deprecated. Using Drush to download Drupal core or contributed modules will throw a warning to use Composer instead.

The pm-download command will download packages from Drupal.org. The site-install command will allow you to specify an installation profile and other options to install a Drupal site. The installation steps in this recipe could be run through Drush, as follows:

$ cd /path/to/web
$ drush pm-download drupal-8 drupal8
$ cd drupal8
$ drush site-install standard -locale=en-US --account-name=admin --account-pass=admin -account-email=demo@example.com -db-url=mysql://user:pass@localhost/database

We used Drush to download the latest Drupal 8 and place it in a folder named drupal8. Then, the site-install command instructs Drush to use the standard install profile, configure the maintenance account, and provide a database URI string so that Drupal can connect to its database.
