5 * Configuration file for multi-site support and directory aliasing feature.
7 * This file is required for multi-site support and also allows you to define a
8 * set of aliases that map hostnames, ports, and pathnames to configuration
9 * directories in the sites directory. These aliases are loaded prior to
10 * scanning for directories, and they are exempt from the normal discovery
11 * rules. See default.settings.php to view how Drupal discovers the
12 * configuration directory when no alias is found.
14 * Aliases are useful on development servers, where the domain name may not be
15 * the same as the domain of the live server. Since Drupal stores file paths in
16 * the database (files, system table, etc.) this will ensure the paths are
17 * correct when the site is deployed to a live server.
19 * To activate this feature, copy and rename it such that its path plus
20 * filename is 'sites/sites.php'.
22 * Aliases are defined in an associative array named $sites. The array is
23 * written in the format: '<port>.<domain>.<path>' => 'directory'. As an
24 * example, to map https://www.drupal.org:8080/mysite/test to the configuration
25 * directory sites/example.com, the array should be defined as:
28 * '8080.www.drupal.org.mysite.test' => 'example.com',
31 * The URL, https://www.drupal.org:8080/mysite/test/, could be a symbolic link
32 * or an Apache Alias directive that points to the Drupal root containing
33 * index.php. An alias could also be created for a subdomain. See the
34 * @link https://www.drupal.org/documentation/install online Drupal installation guide @endlink
35 * for more information on setting up domains, subdomains, and subdirectories.
37 * The following examples look for a site configuration in sites/example.com:
39 * URL: http://dev.drupal.org
40 * $sites['dev.drupal.org'] = 'example.com';
42 * URL: http://localhost/example
43 * $sites['localhost.example'] = 'example.com';
45 * URL: http://localhost:8080/example
46 * $sites['8080.localhost.example'] = 'example.com';
48 * URL: https://www.drupal.org:8080/mysite/test/
49 * $sites['8080.www.drupal.org.mysite.test'] = 'example.com';
