首先，在我的运行 PHP 5.3.15 的 Macbook Pro 开发服务器上，使用 PECL 成功安装了 Memcache 和 APC（并被验证为工作）

我刚刚烘焙了一个测试 Cake 2.2.2 应用程序。在Config/core.php我有以下内容：

/**
 * Pick the caching engine to use.  If APC is enabled use it.
 * If running via cli - apc is disabled by default. ensure it's available and enabled in this case
 *
 */
$engine = 'File';
if (extension_loaded('apc') && function_exists('apc_dec') && (php_sapi_name() !== 'cli' || ini_get('apc.enable_cli'))) {
    $engine = 'Apc';
}
if (extension_loaded('memcache') && php_sapi_name() !== 'cli') {
    $engine = 'Memcache';
}

// In development mode, caches should expire quickly.
$duration = '+999 days';
if (Configure::read('debug') >= 1) {
    $duration = '+10 seconds';
}

// Prefix each application on the same server with a different string, to avoid Memcache and APC conflicts.
$prefix = 'mcmyapp_';

/**
 * Configure the cache used for general framework caching.  Path information,
 * object listings, and translation cache files are stored with this configuration.
 */
Cache::config('_cake_core_', array(
    'engine' => $engine,
    'prefix' => $prefix . 'cake_core_',
    'path' => CACHE . 'persistent' . DS,
    'serialize' => ($engine === 'File'),
    'duration' => $duration
));

/**
 * Configure the cache for model and datasource caches.  This cache configuration
 * is used to store schema descriptions, and table listings in connections.
 */
Cache::config('_cake_model_', array(
    'engine' => $engine,
    'prefix' => $prefix . 'cake_model_',
    'path' => CACHE . 'models' . DS,
    'serialize' => ($engine === 'File'),
    'duration' => $duration
));


Cache::config('default', array(
    'engine' => $engine,
    'serialize' => ($engine === 'File'),
    'duration'=>$duration,
    'prefix'=>$prefix,
));

debug(Cache::settings());

上述最终 debug() 的输出为：

array(
    'prefix' => '*****',
    'engine' => 'Memcache',
    'serialize' => false,
    'duration' => (int) 10,
    'servers' => array(
        (int) 0 => '127.0.0.1'
    ),
    'compress' => false,
    'persistent' => true,
    'probability' => (int) 100,
    'groups' => array()
)

因此core.php，Cake 似乎希望将 Memcache 用作其缓存引擎。

然而，当我localhost/myapp/pages/home在浏览器中访问时，CakePHP 的默认、新鲜出炉的欢迎页面向我打招呼，通知我The FileEngine is being used for core caching

如果我在我的应用程序中的其他任何地方（除了core.php）debug(Cache::settings())，我会得到以下信息：

array(
    'prefix' => '*****',
    'engine' => 'File',
    'serialize' => false,
    'duration' => (int) 10,
    'servers' => array(
        (int) 0 => '127.0.0.1'
    ),
    'compress' => false,
    'persistent' => true,
    'probability' => (int) 100,
    'groups' => array()
)

基本上，CakePHP 似乎恢复为 File 进行缓存，忽略我的配置core.php以使用 Memcache ......除非我在这里做错了什么？？！

Configure::write('debug', 0)我已经用and试过了Configure::write('debug', 1)。

我应该提到，通过上述，APC 和 Memcache 扩展都在php.ini.

任何帮助将不胜感激，在此先感谢。

Memcached 应该在某个端口上，默认端口是 11211（检查）...因此您的配置尝试连接到 Memcached，失败并恢复为默认（文件）缓存...

尝试：

Cache::config('default', array(
    'engine' => 'Memcache',
    'duration'=> 3600, 
    'probability'=> 100, 
    'servers' => array('127.0.0.1:11211') <<<<==
));
