Before the application can be run, you will need to make a few changes to the application/bootstrap.php file. This file is the first one to be included by index.php and sets up most of the global options for the application.
Open application/bootstrap.php and make the following changes:

Set the default timezone for your application.

// Example of changing timezone to Sao Paulo, Brazil
date_default_timezone_set('America/Sao_Paulo');

Set the base_url in the KO7::init call to reflect the location of the koseven folder on your server relative to the document root.

/**
 * Example of koseven's installation at /var/www/koseven and
 * Apache's DocumentRoot configured to /var/www/koseven/public
 */
 Kohana::init(array(
     'base_url' => '/',
 ));

List your trusted hosts. Open application/config/url.php and add regex patterns of the hosts you expect your application to be accessible from.

return array(
    'trusted_hosts' => array(
        'example\.org',
        '.*\.example\.org',
    ),
);

Define a salt for the Cookie class.

Cookie::$salt = 'some-really-long-cookie-salt-here';

Make sure the application/cache and application/logs directories are writable by the web server.

sudo chmod -R a+rwx application/cache
sudo chmod -R a+rwx application/logs

Make sure to use a unique salt for your application and never to share it. Take a look at the Cookies page for more information on how cookies work in Kohana. If you do not define a Cookie::$salt value, Kohana will throw an exception when it encounters any cookie on your domain.

Test your installation by opening http://localhost/

You should see the installation page. If it reports any errors, you will need to correct them before continuing.


Once your install page reports that your environment is set up correctly you need to either rename or delete install.php. Kohana is now installed and you should see the output of the welcome controller:
