SQLITE REQUIREMENTS-------------------To use SQLite with your Drupal installation, the following requirements must bemet: Server has PHP 5.2 or later with PDO, and the PDO SQLite driver must beenabled.SQLITE DATABASE CREATION------------------------The Drupal installer will create the SQLite database for you. The onlyrequirement is that the installer must have write permissions to the directorywhere the database file resides. This directory (not just the database file) alsohas to remain writeable by the web server going forward for SQLite to continue tobe able to operate.On the "Database configuration" form in the "Database file" field, you mustsupply the exact path to where you wish your database file to reside. It isstrongly suggested that you choose a path that is outside of the webroot, yetensure that the directory is writeable by the web server.If you must place your database file in your webroot, you could try using thefollowing in your "Database file" field: sites/default/files/.ht.sqliteNote: The .ht in the name will tell Apache to prevent the database from beingdownloaded. Please check that the file is, indeed, protected by your webserver.If not, please consult the documentation of your webserver on how to protect afile from downloading.
