Question

我的redis群集正在侦听所有接口，并允许任何主机。 Telnet到redis是可以的：

-NOAUTH Authentication required.
auth xxxx
+OK
get a
$1
a

iptables是空的：

        [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

创建了Redis群集：

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

让我告诉你代码：

    //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);
}

六个机构（3个主机和3个从机）位于一个主机中，监听端口来自5067/5167/5267/5367/5467/5567 redis群集安装在TenCent Cloud Virtual Machine

中

我在自己的电脑上运行我的代码。该网络是中国电信全家宽带。

我正在使用：

redis 4.0.8

jedis 2.9.0

谢谢！
