CakePHP缓存配置始终恢复为文件（从Memcache或APC）

首先，在运行PHP5.3.15的Macbook Pro dev服务器上，使用PECL成功安装了Memcache和APC（并验证其工作正常）

我刚刚烤了一个测试蛋糕2.2.2应用程序。在

Config/core.php

中，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());

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()
)

上述最终调试（）的输出为：

因此，在

core.php

中，Cake似乎希望使用Memcache作为其缓存引擎

但是，当我在浏览器中访问

localhost/myapp/pages/home

时，CakePHP的默认、新烘焙的欢迎页面向我打招呼，通知我

文件引擎正在用于核心缓存

在我的应用程序中的任何其他地方（除了

core.php

），如果我

debug（Cache:：settings（））

，我会得到以下信息：

/**
 * 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());

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似乎恢复到文件进行缓存，忽略了我在

core.php

中使用Memcache的配置。。。除非我做错了什么

我已经用

Configure:：write（'debug'，0）

和

Configure:：write（'debug'，1）

尝试过这一点

我应该提到的是，有了上述功能，APC和Memcache扩展都在

php.ini

中启用

感谢您的帮助。

Memcached应该在某个端口上，默认为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：

缓存：：配置（'default'，数组( “引擎”=>“内存缓存”， “持续时间”=>3600， “概率”=>100，

'servers'=>array（'127.0.0.1:11211'）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：
