Question

我有3个运行Redis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连接到每个服务器上的每个服务器。

但是当我运行群集创建时，脚本永远不会在Server 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
Waiting for the cluster to join

配置中缺少某些内容吗？

在EC2实例上可能无法访问Redis群集端口。

来自Redis Cluster Specification：

每个Redis Cluster节点都有一个额外的TCP端口，用于接收来自其他Redis Cluster节点的传入连接。此端口与用于从客户端接收传入连接的普通TCP端口处于固定偏移量。要获得Redis Cluster端口，应在常规命令端口中添加10000。例如，如果Redis节点正在端口6379上侦听客户端连接，则群集总线端口16379也将打开。

Redis集群等待集群加入私有VPC
