If anyone face the error 'The requested address '/' was not found on this server' in cakePHP, then try these two steps:-

1. Add function date_default_timezone_set() somewhere in you cake/app folder.
2. If above solution not works then place date_default_timezone_set('UTC') function in your /var/www/html/lib/Cake/Cache/cacheEngine.php file under the function init() like this:-

public function init($settings = array()) {
        date_default_timezone_set('UTC'); // add new line
        $settings += $this->settings + array(
            'prefix' => 'cake_',
            'duration' => 3600,
            'probability' => 100,
            'groups' => array()
        );
        $this->settings = $settings;
        if (!empty($this->settings['groups'])) {
            sort($this->settings['groups']);
            $this->_groupPrefix = str_repeat('%s_', count($this->settings['groups']));
        }
        if (!is_numeric($this->settings['duration'])) {
            $this->settings['duration'] = strtotime($this->settings['duration']) - time();
        }
        return true;
    }

Second solution works for me. I hope it will work for you.
