cassandra 中的两个节点不会互相闲聊

Question

节点0：
configuration.yaml 文件：
cluster_name: 'ServerCluster'
令牌数：256
种子：“”
监听地址：10.104.0.15
rpc_address：10.104.0.15
自动引导：假
endpoint_snitch: GossipingPropertyFileSnitch

cassandra-env.sh 文件：JVM_OPTS="$JVM_OPTS -java.rmi.server.hostname=10.104.0.15"
cassandra-rackdc 文件：dc=DC1rack=RAC1

节点1：
configuration.yaml 文件：
cluster_name: 'ServerCluster'
令牌数：256
种子：“10.104.0.15”
监听地址：10.104.0.20
rpc_address：10.104.0.20
自动引导：真
endpoint_snitch: GossipingPropertyFileSnitch

cassandra-env.sh 文件：JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=10.104.0.20"
cassandra-rackdc 文件：dc=DC1rack=RAC1

Node0 正常运行
节点 1 错误：

然后我更改了种子（因为在 * 中看到了解决方案）
节点0：

节点1：

Node0 很好

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

即使我关注了datastax链接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

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。再次启动每个节点。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，请确保您可以访问它们（使用 telnet 进行检查）。

http://docs.datastax.com/en/cassandra/2.0/cassandra/security/secureFireWall_r.html

Answer 2

我不确定这是否能解决您的问题。但这是一个很好的建议。

所有节点都应该有相同的种子，并且数据中心应该至少有一个种子。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"

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？
