我们在 AWS 上部署了 Cassandra 集群，在 Auto Scaling 组中有 3 个种子节点（附加静态 ENI）和 3 个非种子节点。

我将 rpc_address 设置为 0.0.0.0，谁能告诉我 cassandra.yaml 文件中的 broadcast_rpc_address 应该是什么？

我之前使用的是 cassandra 2.0.7 版本，并且能够很好地连接到集群，只需将 rpc_address 设置为 0.0.0.0 并且没有设置 broadcast_rpc_address ，但是当我升级到 3.11.1 时它给了我错误

CassandraDaemon.java:708 - Exception encountered during startup: If rpc_address is set to a wildcard address (0.0.0.0), then you must set broadcast_rpc_address to a value other than 0.0.0.0

如果您使用的是 Cassandra 2.1 或更高版本，您可以配置 broadcast_rpc_address。你可以配置broadcast_rpc_address为公网IP。

Cassandra 将“broadcast_address/listen_address”用于节点间连接，将“broadcast_rpc_address/rpc_address”用于 rpc 接口（客户端 -> 协调器（Cassandra 节点）请求）。
