redis 单例化

connRedis();
    }
    /**
     * 连接ocean 上的redis的私有化方法
     * @return Redis
    */
    static private function connRedis()
    {
        try {
            $redis_ocean = new Redis();
            $redis_ocean->connect(self::host, self::port);
            $redis_ocean->auth(self::pass);
        }catch (Exception $e){
            echo $e->getMessage().'
';
        }
        return $redis_ocean;
    }
}

使用文件中： 

include_once(ROOT_PATH .'redis/redisconfig.php');    
$list = $Redis->lrange($redisListName, 0, -1);
