代码如下，代码为memcache官方代码，引用在此，做一下简单的说明：
1、设置用户名和密码
define('admin_username','admin'); // admin username
define('admin_password','123456');   // admin password
2、配置服务器及其端口，可以配置多台
$memcache_servers[] = 'localhost:11211'; // add more as an array
$memcache_servers[] = 'localhost:11212'; // add more as an array
