PHP Fatal error: Uncaught exception 'Zend_Cache_Exception' with message 'cache_dir “/tmp” must be a directory'

I have problem regarding zend cache_dir. I try to tranfer my site from one server to another, and it work. But, when i try to access the site, it shows this error:

PHP Fatal error:  Uncaught exception 'Zend_Cache_Exception' with message 'cache_dir "/tmp" must be a directory' in /home/aiesorgm/public_html/gcpi/library/Zend/Cache.php:209

I already try all solutions that i can get from stackoverflow, but it's still doesn't work. I also have create tmp directory inside public folder and change the permission to 777.

application/Bootstrap.php

protected function _initCache() {
    $info = Zend_Registry::get('info');

    $backendOptions = array(
        'cache_dir' => sys_get_temp_dir(),
        'hashed_directory_level' => 1,
        'file_name_prefix' => 'style',
        'automatic_cleaning_factor' => 1
    );
    $frontendOptions = array(
        'lifetime' => $info['cache']['lifetime'],
        'automatic_serialization' => true,
        'caching' => ($info['cache']['enabled'] == '1') ? true : false,
    );
    $cache = Zend_Cache::factory('Page', 'File', $frontendOptions, $backendOptions);
    Zend_Registry::set('cache', $cache);
}
