java连接redis失败，我关掉了防火墙。注释了bind，还是不成功。

Question

1，关闭防火墙==========

2，注释掉bind========

3，但是代码还是不能通过=====

 public static void main(String[] args) {
          //连接本地的 Redis 服务
          Jedis jedis = new Jedis("localhost");
          System.out.println("Connection to server sucessfully");
          //查看服务是否运行
          System.out.println("Server is running: "+jedis.ping());
     }
=======下面是报错=====

Exception in thread "main" redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused: connect
    at redis.clients.jedis.Connection.connect(Connection.java:134)
    at redis.clients.jedis.BinaryClient.connect(BinaryClient.java:69)
