Redis集群等待集群加入Private VPC

Question

我有3个使用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台。

但是，当我运行集群创建时，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

配置中缺少什么？

Answer 1

可能在EC2实例上无法访问Redis Cluster端口。

根据Redis群集规范：

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。该端口与用于接收来自客户端的传入连接的正常TCP端口有固定的偏移量。要获取Redis Cluster端口，应将10000添加到正常命令端口。例如，如果Redis节点正在监听端口6379上的客户端连接，则也将打开Cluster总线端口16379。
