If you make changes to this file, be sure to protect it again * after making your modifications. Failure to remove write permissions * to this file is a security risk. * * The configuration file to be loaded is based upon the rules below. * * The configuration directory will be discovered by stripping the * website's hostname from left to right and pathname from right to * left. The first configuration file found will be used and any * others will be ignored. If no other configuration file is found * then the default configuration file at 'sites/default' will be used. * * For example, for a fictitious site installed at * http://www.drupal.org/mysite/test/, the 'settings.php' * is searched in the following directories: * * 1. sites/www.drupal.org.mysite.test * 2. sites/drupal.org.mysite.test * 3. sites/org.mysite.test * * 4. sites/www.drupal.org.mysite * 5. sites/drupal.org.mysite * 6. sites/org.mysite * * 7. sites/www.drupal.org * 8. sites/drupal.org * 9. sites/org * * 10. sites/default * * If you are installing on a non-standard port number, prefix the * hostname with that number. For example, * http://www.drupal.org:8080/mysite/test/ could be loaded from * sites/8080.www.drupal.org.mysite.test/. */ /** * Database settings: * * The $databases array specifies the database connection or * connections that Drupal may use. Drupal is able to connect * to multiple databases, including multiple types of databases, * during the same request. * * Each database connection is specified as an array of settings, * similar to the following: * @code * array( * 'driver' => 'mysql', * 'database' => 'databasename', * 'username' => 'username', * 'password' => 'password', * 'host' => 'localhost', * 'port' => 3306, * 'prefix' => '@@DB_MAIN_PREFIX@@', 'transactions' => FALSE, * 'collation' => 'utf8_general_ci', * ); * @endcode * * The "driver" property indicates what Drupal database driver the * connection should use. This is usually the same as the name of the * database type, such as mysql or sqlite, but not always. The other * properties will vary depending on the driver. For SQLite, you must * specify a database file name in a directory that is writable by the * webserver. For most other drivers, you must specify a * username, password, host, and database name. * * Some database engines support transactions. In order to enable * transaction support for a given database, set the 'transactions' key * to TRUE. To disable it, set it to FALSE. Note that the default value * varies by driver. For MySQL, the default is FALSE since MyISAM tables * do not support transactions. * * For each database, you may optionally specify multiple "target" databases. * A target database allows Drupal to try to send certain queries to a * different database if it can but fall back to the default connection if not. * That is useful for master/slave replication, as Drupal may try to connect * to a slave server when appropriate and if one is not available will simply * fall back to the single master server. * * The general format for the $databases array is as follows: * @code * $databases['default']['default'] = $info_array; * $databases['default']['slave'][] = $info_array; * $databases['default']['slave'][] = $info_array; * $databases['extra']['default'] = $info_array; * @endcode * * In the above example, $info_array is an array of settings described above. * The first line sets a "default" database that has one master database * (the second level default). The second and third lines create an array * of potential slave databases. Drupal will select one at random for a given * request as needed. The fourth line creates a new database with a name of * "extra". * * For a single database configuration, the following is sufficient: * @code * $databases['default']['default'] = array( * 'driver' => 'mysql', * 'database' => 'databasename', * 'username' => 'username', * 'password' => 'password', * 'host' => 'localhost', * 'prefix' => '@@DB_MAIN_PREFIX@@', 'transactions' => FALSE, * 'collation' => 'utf8_general_ci', * ); * @endcode * * You can optionally set prefixes for some or all database table names * by using the 'prefix' setting. If a prefix is specified, the table * name will be prepended with its value. Be sure to use valid database * characters only, usually alphanumeric and underscore. If no prefixes * are desired, leave it as an empty string ''. * * To have all database names prefixed, set 'prefix' as a string: * @code * 'prefix' => '@@DB_MAIN_PREFIX@@', 'transactions' => FALSE, * @endcode * To provide prefixes for specific tables, set 'prefix' as an array. * The array's keys are the table names and the values are the prefixes. * The 'default' element is mandatory and holds the prefix for any tables * not specified elsewhere in the array. Example: * @code * 'prefix' => '@@DB_MAIN_PREFIX@@', 'transactions' => FALSE, * 'default' => 'main_', * 'users' => 'shared_', * 'sessions' => 'shared_', * 'role' => 'shared_', * 'authmap' => 'shared_', * ), * @endcode * You can also use a reference to a schema/database as a prefix. This maybe * useful if your Drupal installation exists in a schema that is not the default * or you want to access several databases from the same code base at the same * time. * Example: * @code * 'prefix' => '@@DB_MAIN_PREFIX@@', 'transactions' => FALSE, * 'default' => 'main.', * 'users' => 'shared.', * 'sessions' => 'shared.', * 'role' => 'shared.', * 'authmap' => 'shared.', * ); * @endcode * NOTE: MySQL and SQLite's definition of a schema is a database. * * Database configuration format: * @code * $databases['default']['default'] = array( * 'driver' => 'mysql', * 'database' => 'databasename', * 'username' => 'username', * 'password' => 'password', * 'host' => 'localhost', * 'prefix' => '@@DB_MAIN_PREFIX@@', 'transactions' => FALSE, * ); * $databases['default']['default'] = array( * 'driver' => 'pgsql', * 'database' => 'databasename', * 'username' => 'username', * 'password' => 'password', * 'host' => 'localhost', * 'prefix' => '@@DB_MAIN_PREFIX@@', 'transactions' => FALSE, * ); * $databases['default']['default'] = array( * 'driver' => 'sqlite', * 'database' => '/path/to/databasefilename', * ); * @endcode */ $databases = array ( 'default' => array ( 'default' => array ( 'database' => '@@DB_MAIN_NAME@@', 'username' => '@@DB_MAIN_LOGIN@@', 'password' => '@@DB_MAIN_PASSWORD@@', 'host' => '@@DB_MAIN_HOST@@', 'port' => '@@DB_MAIN_PORT@@', 'driver' => '@@DB_MAIN_TYPE@@', 'prefix' => '@@DB_MAIN_PREFIX@@', 'transactions' => FALSE, ), ), ); /** * Access control for update.php script. * * If you are updating your Drupal installation using the update.php script but * are not logged in using either an account with the "Administer software * updates" permission or the site maintenance account (the account that was * created during installation), you will need to modify the access check * statement below.
