Java JedisCluster在2.7.x中工作，但不'；在绝地2.9.x版本中，绝地连接异常和连接被拒绝

我的代码在绝地2.7.x中保存了几个月。但我发现我的问题与（redis服务器重新启动时JedisPool.getResource块）相同。所以我从2.7.x切换到了2.9.x。我正在使用相同的代码创建JedisCluster。但它无法连接绝地并从绝地获取数据

我创建了一个单例JedisCluster实例，每次我只使用JedisCluster.get（）获取数据。我不关闭群集的连接

---

更多信息：我的redis是3.2.8。我使用单一主机作为绝地群集，没有奴隶。我之所以想使用绝地群集模式而不是绝地模式，是因为我有另一个系统需要调用多主机的绝地群集。我想首先在当前单主机集群中测试代码，然后将代码部署到该系统

cluster_state:ok
cluster_slots_assigned:16384
cluster_slots_ok:16384
cluster_slots_pfail:0
cluster_slots_fail:0
cluster_known_nodes:1
cluster_size:1
cluster_current_epoch:0
cluster_my_epoch:0
cluster_stats_messages_sent:0
cluster_stats_messages_received:0

相同的代码在2.7.x中工作，但在2.9.x中不工作

@Singleton
JedisCluster jedisCluster(){
        Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
        jedisClusterNodes.add(new HostAndPort("10.xx.xx.xx", 6379));
        GenericObjectPoolConfig jedisPoolConfig = new GenericObjectPoolConfig();
        jedisPoolConfig.setMaxTotal(16);
        jedisPoolConfig.setMaxIdle(16);
        return new JedisCluster(jedisClusterNodes, 2000, 1000, 5, jedisPoolConfig);
}
//When using cluster
jedisCluster.set("foo", "bar");
String value = jedisCluster.get("foo");

我使用ssh连接到Redis主机并运行cli

127.0.0.1:6379> get foo
"bar

我得到的例外

我的问题在《绝地圣战》中得到了马科斯·尼尔斯的回答，这让我想到了

以前我没有在我的单一主机中创建集群，我可以直接在2.7.x中将其作为集群使用。我运行下面的命令解决了我的问题

for i in {0..16383}; do bin/redis-cli -h <ipOfHost1> CLUSTER ADDSLOTS $i; done
cluster meet <ip> 6379

{0..16383}中i的

；do bin/redis cli-h CLUSTER ADDSLOTS$i；完成
分组会议6379

禁用防火墙我觉得防火墙可能不是问题，因为我的系统可以连接到绝地2.7.x中的绝地群集，并且可以通过绝地2.9.x中的“新绝地”（“xx.xx.xxx.xx”，6379）”使用绝地。唯一的问题是它无法连接到绝地2.9.x中的绝地群集。更多信息：我的redis是3.2.8。我使用单一主机作为绝地群集，没有奴隶。我之所以想使用绝地群集模式而不是绝地模式，是因为我有另一个系统需要调用多主机的绝地群集。我想首先在当前单主机集群中测试代码，然后将代码部署到该系统。

for i in {0..16383}; do bin/redis-cli -h <ipOfHost1> CLUSTER ADDSLOTS $i; done
