SQLITE REQUIREMENTS ------------------- PHP's PDO SQLite driver must be enabled. If you do not have pdo_sqlite available, depending on your system there are different ways to install it. Windows ------- Read more about it on http://www.php.net/manual/en/pdo.installation.php Linux ----- sudo apt-get install php-sqlite3 SQLITE DATABASE CREATION ------------------------ The Drupal installer will create the SQLite database for you. The only requirement is that the installer must have write permissions to the directory where the database file resides. This directory (not just the database file) also has to remain writable by the web server going forward for SQLite to continue to be able to operate. On the "Database configuration" form in the "Database file" field, you must supply the exact path to where you wish your database file to reside. It is strongly suggested that you choose a path that is outside of the webroot, yet ensure that the directory is writable by the web server. If you must place your database file in your webroot, you could try using the following in your "Database file" field: sites/default/files/.ht.sqlite Note: The .ht in the name will tell Apache to prevent the database from being downloaded. Please check that the file is, indeed, protected by your webserver. If not, please consult the documentation of your webserver on how to protect a file from downloading.
