Cassandra未啓動

Question

我在AWS上遇到3節點Cassandra羣集問題。 有一個種子節點和兩個數據節點。當它們啓動時以及當我嘗試手動啓動它們時，節點將崩潰 。

錯誤消息出現在所有三個節點中。

Cassandra的版本是2.0.9

我曾嘗試以下設置：

- 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). 

的錯誤消息是

ERROR [main] 2014-09-29 08:59:45,241 CassandraDaemon.java (line 513) Exception encountered during startup 
java.lang.RuntimeException: Unable to gossip with any seeds

端口7000，7001，7199，8080，9042， 9160，61620和61621在羣集的安全組中打開。

我也看到了，並試圖在以下鏈接中給出的解決方案：

Answer 1

Cassandra無法綁定到EC2中的公共IP地址。

與公共DNS或 在listen_address的私有IP地址，rpc_address和種子更換它。

公有DNS正在解析私有IP地址，該私有IP地址是EC2實例中的eth0內部地址，其中Cassandra是綁定的。

工作的配置是：

- 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).
