1、首先弄清楚memcache和memcached的区别（自行搜索）

2、安装memcache服务端（参照https://www.cnblogs.com/winstonsias/p/10190745.html）及php扩展（参照https://www.cnblogs.com/winstonsias/p/10193781.html）

3、添加服务提供类 MemcacheServiceProvider ，记得在app.php配置文件添加提供者注册

 1  namespace App\Providers; 2  3 use Cache; 4 use App\Extensions\MemcacheStore; 5 use Illuminate\Support\ServiceProvider; 6  7 class MemcacheServiceProvider extends ServiceProvider 8  { 9 public function boot()10  {11 Cache::extend(‘memcache‘, function ($app) {12 return Cache::repository(new MemcacheStore($app[‘memcache.connector‘]));13  });14  }15 16 public function register()17  {18 //注册memcache连接的单例19 $this->app->singleton(‘memcache.connector‘, function ($app) {20 $config = $app[‘config‘]["cache.stores.memcache"];21 $servers = $config[‘servers‘][0];22 return memcache_connect($servers[‘host‘], $servers[‘port‘]);23  });24  }25 26 27 }

4、完善存储类MemcacheStore（可在app添加Extensions文件夹存放）

 1  namespace App\Extensions; 2 class MemcacheStore implements \Illuminate\Contracts\Cache\Store 3  { 4 //memcache资源 5 protected $memcache_conn; 6 public function __construct($conn) 7  { 8 $this->memcache_conn=$conn; 9  }10 11 public function __destruct()12  {13 // TODO: Implement __destruct() method.14 $this->memcache_conn=null;//释放资源15  }16 17 public function get($key)18  {19 return $this->memcache_conn->get($key);20  }21 22 public function put($key, $value, $minutes)23  {24  }25 26 public function increment($key, $value = 1)27  {28  }29 30 public function decrement($key, $value = 1)31  {32  }33 34 public function forever($key, $value)35  {36  }37 38 public function forget($key)39  {40  }41 42 public function flush()43  {44  }45 46 public function getPrefix()47  {48  }49 50 /**51  * Retrieve multiple items from the cache by key.52  *53  * Items not found in the cache will have a null value.54  *55  * @param array $keys56  * @return array57 */58 public function many(array $keys)59  {60 // TODO: Implement many() method.61  }62 63 /**64  * Store multiple items in the cache for a given number of minutes.65  *66  * @param array $values67  * @param int $minutes68  * @return void69 */70 public function putMany(array $values, $minutes)71  {72 // TODO: Implement putMany() method.73  }74 }

5、在cache.php配置文件中添加自定义缓存store

 1 /** 2  * 自定义memcache，不用memcached by winston 3 */ 4 ‘memcache‘ => [ 5 ‘driver‘ => ‘memcache‘, 6 ‘servers‘ => [ 7  [ 8 ‘host‘ => env(‘MEMCACHED_HOST‘, ‘xx.xx.xx.xx‘), 9 ‘port‘ => env(‘MEMCACHED_PORT‘, 11211),10 ‘weight‘ => 100,11 ],12 ],13 ],

6、在控制器中使用

1 $val=Cache::store(‘memcache‘)->get(‘xxxx‘);
