Redis Clustering 等待集群加入Private VPC

Question

我有 3 个带有 Redis 运行的 EC2 实例，如下所示：

服务器 001：10.0.1.203，端口：6379
服务器 002：10.0.1.202，端口：6380
服务器 003：10.0.1.190，端口：6381

每个配置文件：

# bind 127.0.0.1
protected-mode no
port PORT
pidfile /var/run/redis_PORT.pid
cluster-enabled yes
cluster-config-file nodes-PORT.conf
cluster-node-timeout 15000

我可以通过 redis 连接到每台服务器上的每一个。

但是当我运行创建集群时，脚本永远不会在服务器 001 上结束。

Can I set the above configuration? (type 'yes' to accept): yes
>>> Nodes configuration updated
>>> Assign a different config epoch to each node
>>> Sending CLUSTER MEET messages to join the cluster

服务器 002 日志：

服务器 003 日志：

44033:M 02 Nov 2020 13:30:50.695 * Node hard reset, now I'm 14d39c0876a982cadd50f301a3d35715171279c0
44033:M 02 Nov 2020 13:30:59.346 # configEpoch set to 3 via CLUSTER SET-CONFIG-EPOCH

我在配置上遗漏了什么吗？

可能无法在 EC2 实例上访问 Redis 集群端口。

来自Redis Cluster Specification：

Every Redis Cluster node has an additional TCP port for receiving incoming connections from other Redis Cluster nodes. This port is at a fixed offset from the normal TCP port used to receive incoming connections from clients. To obtain the Redis Cluster port, 10000 should be added to the normal commands port. For example, if a Redis node is listening for client connections on port 6379, the Cluster bus port 16379 will also be opened.
