Laravel5框架在Cache和Session中不支持Memcache，看清了是Memcache而不是Memcached哦，MemCached是支持的但是这个扩展真的是装的蛋疼，只有修改部分源码让其来支持memcache了。具体修改部分如下：
找到sessioni管理器 Laravel\vendor/laravel/framework/src/Illuminate/Session/SessionManager.php，并增加如下代码：
/**
* Create an instance of the Memcached session driver.
*
* @return IlluminateSessionStore
*/
protected function createMemcacheDriver()
{
return $this->createCacheBased('memcache');
}
接下来修改cache部分，找到Laravel/vendor/laravel/framework/src/Illuminate/Cache/CacheManager.php
在该文件中增加以下代码：
/**
* Create an instance of the Memcache cache driver.
*
* @return IlluminateCacheMemcachedStore
*/
protected function createMemcacheDriver(array $config)
{
$prefix = $this->getPrefix($config); $memcache = $this->app['memcache.connector']->connect($config['servers']); return $this->repository(new MemcacheStore($memcache, $prefix));
}
接下来找到文件： Laravel/vendor/laravel/framework/src/Illuminate/Cache/CacheServiceProvider.php 将memcache注册进去
修改如下：
/**
* Register the service provider.
*
* @return void
*/
public function register()
{
$this->app->singleton('cache', function ($app) {
return new CacheManager($app);
}); $this->app->singleton('cache.store', function ($app) {
return $app['cache']->driver();
}); $this->app->singleton('memcached.connector', function () {
return new MemcachedConnector;
}); $this->app->singleton('memcache.connector',function() {
// 这里返回了MemcacheConnector,记得在Cache目录下创建这个class
return new MemcacheConnector;
});
$this->registerCommands();
}
/**
* Get the services provided by the provider.
*
* @return array
*/
public function provides()
{
return [
'cache', 'cache.store', 'memcached.connector', 'command.cache.clear','memcache.connector'
];
}
我们看到这个闭包函数中返回了MemcacheContector的对象，现在来创建此类。文件位置：Laravel/vendor/laravel/framework/src/Illuminate/Cache/MemcacheConnector.php
<?php
namespace Illuminate\Cache; use Memcache;
use RuntimeException; class MemcacheConnector { /**
* Create a new Memcached connection.
*
* @param array $servers
* @return Memcache
*/
public function connect(array $servers)
{
$memcache = $this->getMemcache(); // For each server in the array, we'll just extract the configuration and add
// the server to the Memcache connection. Once we have added all of these
// servers we'll verify the connection is successful and return it back.
foreach ($servers as $server)
{
$memcache->addServer($server['host'], $server['port'], $server['weight']);
} if ($memcache->getVersion() === false)
{
throw new RuntimeException("Could not establish Memcache connection.");
} return $memcache;
} /**
* Get a new Memcache instance.
*
* @return Memcached
*/
protected function getMemcache()
{
return new Memcache;
}
}
按照第二步的流程这个文件会执行connect的方法，执行完成之后返回一个Memcache的对象， 这时候第二步那里根据这边来创建了一个MemcacheStore的存储器。
文件地址：Laravel/vendor/laravel/framework/src/Illuminate/Cache/MemcacheStore.php
<?php namespace Illuminate\Cache; use Memcache;
use Illuminate\Contracts\Cache\Store; class MemcacheStore extends TaggableStore implements Store
{
/**
* The Memcached instance.
*
* @var \Memcached
*/
protected $memcached; /**
* A string that should be prepended to keys.
*
* @var string
*/
protected $prefix; public function __construct(Memcache $memcache, $prefix = '')
{
$this->memcache = $memcache;
$this->prefix = strlen($prefix) > 0 ? $prefix.':' : '';
} /**
* Retrieve an item from the cache by key.
*
* @param string|array $key
* @return mixed
*/
public function get($key)
{
return $this->memcache->get($this->prefix.$key);
} /**
* Retrieve multiple items from the cache by key.
*
* Items not found in the cache will have a null value.
*
* @param array $keys
* @return array
*/
public function many(array $keys)
{
$prefixedKeys = array_map(function ($key) {
return $this->prefix.$key;
}, $keys); $values = $this->memcache->getMulti($prefixedKeys, null, Memcache::GET_PRESERVE_ORDER); if ($this->memcache->getResultCode() != 0) {
return array_fill_keys($keys, null);
} return array_combine($keys, $values);
} /**
* Store an item in the cache for a given number of minutes.
*
* @param string $key
* @param mixed $value
* @param int $minutes
* @return void
*/
public function put($key, $value, $minutes)
{
$compress = is_bool($value) || is_int($value) || is_float($value) ? false : MEMCACHE_COMPRESSED;
$this->memcache->set($this->prefix.$key, $value, $compress, $minutes * 60);
} /**
* Store multiple items in the cache for a given number of minutes.
*
* @param array $values
* @param int $minutes
* @return void
*/
public function putMany(array $values, $minutes)
{
$prefixedValues = []; foreach ($values as $key => $value) {
$prefixedValues[$this->prefix.$key] = $value;
} $this->memcache->setMulti($prefixedValues, $minutes * 60);
}
/**
* Store an item in the cache if the key doesn't exist.
*
* @param string $key
* @param mixed $value
* @param int $minutes
* @return bool
*/
public function add($key, $value, $minutes)
{
return $this->memcache->add($this->prefix.$key, $value, $minutes * 60);
} /**
* Increment the value of an item in the cache.
*
* @param string $key
* @param mixed $value
* @return int|bool
*/
public function increment($key, $value = 1)
{
return $this->memcache->increment($this->prefix.$key, $value);
} /**
* Decrement the value of an item in the cache.
*
* @param string $key
* @param mixed $value
* @return int|bool
*/
public function decrement($key, $value = 1)
{
return $this->memcache->decrement($this->prefix.$key, $value);
} /**
* Store an item in the cache indefinitely.
*
* @param string $key
* @param mixed $value
* @return void
*/
public function forever($key, $value)
{
$this->put($key, $value, 0);
} /**
* Remove an item from the cache.
*
* @param string $key
* @return bool
*/
public function forget($key)
{
return $this->memcache->delete($this->prefix.$key);
} /**
* Remove all items from the cache.
*
* @return void
*/
public function flush()
{
$this->memcache->flush();
} /**
* Get the underlying Memcached connection.
*
* @return \Memcached
*/
public function getMemcached()
{
return $this->memcache;
} /**
* Get the cache key prefix.
*
* @return string
*/
public function getPrefix()
{
return $this->prefix;
} /**
* Set the cache key prefix.
*
* @param string $prefix
* @return void
*/
public function setPrefix($prefix)
{
$this->prefix = ! empty($prefix) ? $prefix.':' : '';
}
}
上述步骤操作完成后，接下来修改一下config.php中的驱动部分，增加如下代码段：
// 修改为memcached
'default' => env('CACHE_DRIVER', 'memcache'), // stores 部分增加memcache配置
'memcache' => [
'driver' => 'memcache',
'servers' => [
[
'host' => env('MEMCACHED_HOST', '127.0.0.1'),
'port' => env('MEMCACHED_PORT', 11211),
'weight' => 100,
],
],
],
至此完工，尽情享用吧。
