Question

我在AWS上使用3节点Cassandra集群时遇到问题。有一个种子节点和两个数据节点。节点崩溃了当它们被启动时以及我试图手动启动它们时。

错误消息显示在所有三个节点中。

Cassandra的版本是2.0.9

我尝试过以下设置：

- class_name: org.apache.cassandra.locator.SimpleSeedProvider
  parameters:
      - seeds: "<seed.node.public.IP>"

rpc_address: <node.public.IP>

rpc_port: 9160

listen_address: (or with the node's public IP)

storage_port: 7000

endpoint_snitch: SimpleSnitch (and RackInferringSnitch as well).

错误消息是

 ERROR [main] 2014-09-29 08:59:45,241 CassandraDaemon.java (line 513) Exception  encountered during startup

Ports 7000,7001,7199,8080,9042,9160,61620和61621在群集的安全组中打开。

Answer 1

Cassandra无法绑定到EC2中的公共IP地址。

使用公共DNS 或私有IP地址替换它在 listen_address ， rpc_address 和种子。

公共DNS正在解析为私有IP地址关于EC2实例的eth0 intherface，Cassandra具有约束力。

工作配置为：

- class_name: org.apache.cassandra.locator.SimpleSeedProvider
  parameters:
     - seeds: "<seed.node.public.DNS>"

  rpc_address: <node.public.DNS>

  rpc_port: 9160

  listen_address: (or with the node's public DNS)

  storage_port: 7000

  endpoint_snitch: SimpleSnitch (and RackInferringSnitch as well).
