JedisCluster无法使用密码连接到redis集群

Question

我的 redis 集群正在侦听所有接口，并且允许任何主机。 telnet 到 redis 可以:

-NOAUTH Authentication required.
auth xxxx
+OK
get a

a

iptables 为空：

        [centos ]# iptables -L
        Chain INPUT (policy ACCEPT)
        target     prot opt source               destination         

        Chain FORWARD (policy ACCEPT)
        target     prot opt source               destination         

        Chain OUTPUT (policy ACCEPT)
        target     prot opt source               destination

但是当我使用 JedisCluster 时：

 redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool
Caused by: java.net.ConnectException: Connection refused: connect

让我给你看代码：

    //it's successful to connect to all master nodes and get the keys' value
    @Test
    public void testOneByOne() {
    String[] keys = new String[] {
            "b",
            "c",
            "a"

    };
    for (int i = 0; i < 3; i++) {

        Jedis jedis = new Jedis("{myIp}", 5067 + i * 100);
        jedis.auth("{myPassword}");
        String a = jedis.get(keys[i]);
        System.out.println(a); //ok
    }
}

//all the masters and slaves can be connected, so network is ok.
@Test
public void testConnectFromSourceCode() throws Exception {
    for (int i = 0; i < 6; i++) {
        int port = 5067 + i * 100;
        Socket socket = new Socket();
        socket.setReuseAddress(true);
        socket.setKeepAlive(true);
        socket.setTcpNoDelay(true);
        socket.setSoLinger(true, 0);
        socket.connect(new InetSocketAddress("{myIp}", port), 2000);
        socket.setSoTimeout(2000);
        System.out.println("port=" + port + "," + socket.isConnected());//isConnected=true
    }


}

//# error:
// redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool
//Caused by: java.net.ConnectException: Connection refused: connect
@Test
public void testJedisCluster() {
    JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
    jedisPoolConfig.setMaxTotal(10);
    jedisPoolConfig.setMaxIdle(5);
    jedisPoolConfig.setMinIdle(5);
    jedisPoolConfig.setMaxWaitMillis(300000);
    jedisPoolConfig.setTestOnBorrow(true);
    jedisPoolConfig.setTestOnReturn(true);
    jedisPoolConfig.setTestWhileIdle(true);

    HostAndPort hostAndPort = new HostAndPort("{myIp}", 5067);
    JedisCluster jc=new JedisCluster(hostAndPort, 2000,2000,5, "{myPassword}", jedisPoolConfig);
    String a = jc.get("a");
    System.out.println(a);
}

6个实例（3主3从）在一台主机上，监听5067/5167/5267/5367/5467/5567端口 redis集群安装在TenCent Cloud Virtual Machine

我运行我的代码在我自己的电脑上。网络是中国电信家庭宽带

我正在使用：

redis 4.0.8

jedis 2.9.0

谢谢！
