My project folder is demo, inside which I have the folders application, library and public. Inside the application folder, I have a folder named configs, inside which I have a file 'application.ini', which contains my database parameters. So, in the bootstrap.php which is in application directory, I set my database in Zend registry in a function called _initDbAdapter:
$config = new Zend_Config_Ini('/demo/application/configs/application.ini', 'development');
Zend_Registry::set('config', $config);
$db = Zend_Db::factory($config, $config->resources->db->params->asArray());
Zend_register('db', $db);
When I point my browser to localhost/demo/public/ (since my index.php resides in the public folder), I get the following error:
Fatal error: Uncaught exception 'Zend_Config_Exception' with message 'parse_ini_file(/demo/application/configs/application.ini):

You're getting this error because /demo/application/configs/application.ini is not the correct path. Looking at your errors, the full absolute path is /var/www/demo/application/configs/application.ini but you probably want to use APPLICATION_PATH.'/configs/application.ini' which is a more convenient shortcut.
Some time this error occurs due to auto created file
application.ini~ in hidden mode on same path
/demo/application/configs/ So please check hidden file on same path
like /demo/application/configs/application.ini~ if found then remove it.
I solved it by changing the config file param to APPLICATION_PATH.''/configs/application.ini
