Question

首先，在运行PHP 5.3.15的Macbook Pro dev服务器上使用PECL（并验证其工作）成功安装了Memcache和APC

我刚刚发布了一个测试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（）的输出是：

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()
)

所以在core.php中，似乎Cake想要使用Memcache作为其缓存引擎。

然而，当我在浏览器中访问localhost/myapp/pages/home时，CakePHP默认的新鲜出炉的欢迎页面迎接我，告诉我The FileEngine is being used for core caching

我的应用中的其他任何地方（core.php除外）如果我debug(Cache::settings())，我会收到以下信息：

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，忽略我在core.php中的配置以使用Memcache ......除非我在这里做错了什么??！

我已经使用Configure::write('debug', 0)和Configure::write('debug', 1)尝试了此操作。

我应该提一下，在上面，php.ini启用了APC和Memcache扩展。

如果提前感谢，我们将非常感谢您的帮助。

Memcached应该在某个端口上，默认值为11211（检查）...所以你的配置尝试连接到Memcached，失败并恢复到默认（文件）缓存......

尝试：

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

CakePHP Cache Config总是恢复为File（来自Memcache或APC）
