vi app.js(소켓서버 + 레디스 연결)

아례 redisInfo 정보에 알맞게 넣으시면 됩니다.

ex)
host: '3.86.7.129',
port: 6379,
password : '1111'

• 이부분에 경우 attendAuth라는 채널을 구독하고 메세지 채널에 맞는 이벤트 메시지를 전송합니다
  redis.subscribe('attendAuth');

  io.sockets.emit(data.socketCh, {'data' : {
  socket_ch : data.socketCh
  , userId : data.userId
  }});
  }catch (e) {
  console.log(e);
  }
  break;
