接着上文，不可能每次都都去实例化redis，这很麻烦，而且redis的配置没有分离，这样耦合度很高，不利于后续的代码修改，所以有修改了。
首先还是要启动redis-server，
在global.php

  return array(

        ),

    'service_manager' => array(
            'factories' => array(
                'Zend\Db\Adapter\Adapter\Redis' => function ($sm) {
                   $config = $sm->get('Configuration');
                   if(isset($config['redis_config'])){
                       //redis option
                   $config_redis = $config['redis_config'];
                   $redisOption = new \Zend\Cache\Storage\Adapter\RedisOptions();
                   $redisOption->setServer($config_redis['Server'])
                       ->setDatabase($config_redis['Database'])
                       ->setNamespace($config_redis['Namespace'])
                       ->setWritable($config_redis['Writable'])
                       ->setReadable($config_redis['Readable']);
                       return new \Zend\Cache\Storage\Adapter\Redis($redisOption)
                   }
                },
            ),
        ),
);
之后在调用的地方
