Node0 正常运行

然后我换了种子（因为在Whosebug上看到了解决方法）

那么你能帮我解决这个先有鸡还是先有蛋的问题吗？比你提前

连我都跟着datastax link https://academy.datastax.com/courses/ds210-datastax-enterprise-operations-and-performance-tuning/multiple-data-centers-multiple-0
他只是更改了集群名称、listen_address、rpc_address 和种子，当他键入 nodetool status 时，他能够看到它们，但是当我遵循相同的操作时，我只看到它在各自服务器中的状态

Answer 1

我不确定这是否能解决您的问题。但这是个好建议。

所有节点应该有相同的种子，你应该至少有一个数据中心的种子。即使一个节点的唯一种子是它自己。

如果我是你，我会在所有节点上尝试此设置：

seeds: "10.104.0.15, 10.104.0.20"

而且我不明白你为什么没有为节点 1 指定任何 dc、rack。是故意的吗？

Answer 2

停止两个节点。删除数据文件夹。更改配置以将两个节点都作为种子。重新启动每个节点。我怀疑第一次失败的尝试可能有些奇怪。

这里列出了所有需要打开的端口，确保你能访问到它们（使用telnet检查）。
