Setting up a production environment

There are a few things you'll want to do with your application before moving into production.

  1. See the Bootstrap page in the docs. This covers most of the global settings that would change between environments. As a general rule, you should enable caching and disable profiling (Kohana::init settings) for production sites. Route::cache can also help if you have a lot of routes.
  2. Catch all exceptions in application/bootstrap.php, so that sensitive data is cannot be leaked by stack traces. See the example below which was taken from Shadowhand's source.
  3. Turn on APC or some kind of opcode caching. This is the single easiest performance boost you can make to PHP itself. The more complex your application, the bigger the benefit of using opcode caching.

     * Set the environment string by the domain (defaults to Kohana::DEVELOPMENT).
    Kohana::$environment = ($_SERVER['SERVER_NAME'] !== 'localhost') ? Kohana::PRODUCTION : Kohana::DEVELOPMENT;
     * Initialise Kohana based on environment
        'base_url'   => '/',
        'index_file' => FALSE,
        'profile'    => Kohana::$environment !== Kohana::PRODUCTION,
        'caching'    => Kohana::$environment === Kohana::PRODUCTION,
     * Execute the main request using PATH_INFO. If no URI source is specified,
     * the URI will be automatically detected.
    $request = Request::instance($_SERVER['PATH_INFO']);
        // Attempt to execute the response
    catch (Exception $e)
        if (Kohana::$environment === Kohana::DEVELOPMENT)
            // Just re-throw the exception
            throw $e;
        // Log the error
        Kohana::$log->add(Kohana::ERROR, Kohana::exception_text($e));
        // Create a 404 response
        $request->status = 404;
        $request->response = View::factory('template')
          ->set('title', '404')
          ->set('content', View::factory('errors/404'));
    if ($request->send_headers()->response)
        // Get the total memory and execution time
        $total = array(
          '{memory_usage}' => number_format((memory_get_peak_usage() - KOHANA_START_MEMORY) / 1024, 2).'KB',
          '{execution_time}' => number_format(microtime(TRUE) - KOHANA_START_TIME, 5).' seconds');
        // Insert the totals into the response
        $request->response = str_replace(array_keys($total), $total, $request->response);
     * Display the request response.
    echo $request->response;
