If you need to move or reconfigure your Drupal installation, you need to reconfigure values inside the file settings.php.

Important values inside settings.php

‘database’ => ‘drupal123’ – The name of a Database

‘username’ => ‘drupal123’ – Username

‘password’ => ‘123’ – Password

‘host’ => ‘localhost’ – Database server name

‘port’ => – Database Server Port Number

‘driver’ => ‘mysql’ – Type of the Database

‘prefix’ => ‘dru_’ – Prefix for the tables, as usually it consists of minimum 3 symbols and ends with an underscore (optionally)
