You can run your newly installed Kohana 3 application in two ways, either as a subfolder on your webserver, or as a virtual host.

Running Kohana application inside a subfolder

• Edit application/bootstrap.php file and locate the following code:

    Kohana::init(array(
        'base_url'   => '/kohana/',
    ));
  

If your subfolder name is anything other than kohana, use that folder path in the ‘base_url’ settings. For example, if you have installed KO3 in the folder “myapps/testing/kohana3” inside your webserver document root, then change the bootstrap.php code to look like this:

    Kohana::init(array(
        'base_url'   => '/myapps/testing/kohana3/',
    ));

Running Kohana application as a virtual host

• Edit application/bootstrap.php file and locate the following code:

    Kohana::init(array(
        'base_url'   => '/kohana/',
    ));
  

Change it to

    Kohana::init(array(
        'base_url'   => '/',
    ));

[optional] Enable REST urls

If you would like your application to use REST urls, you will need to do a bit more work. Edit application/bootstrap.php file again, and change Kohana::init code to look like this:

    Kohana::init(array(
        'base_url'   => '/',
        'index_file' => FALSE
    )); 

Rename example.htaccess file in the kohana folder to .htaccess for the REST urls to work. If you are running your application inside a subfolder (not as a virtual host), then edit .htaccess file and change the line:

    RewriteBase /

To:

    RewriteBase /myapps/testing/kohana3/

Proceed to Running your Kohana 3 application to see if everything worked out fine. If something does not work, review your code again for typos and incorrect paths, fix them and try again.
