在Cassandra中设置节点间加密

Question

我是Cassandra的新手,希望在Cassandra 1.2.8中设置节点加密.

我已按照此处列出的步骤成功为密钥库和信任库创建了密钥对:http: //docs.oracle.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#CreateKeystore

在Cassandra.yaml文件中,我已将服务器加密选项调整为以下内容:

server_encryption_options:
    internode_encryption: all
    keystore: conf/keystore
    keystore_password: password
    truststore: conf/truststore
    truststore_password: password

但是,当我启动Cassandra服务器时,我收到以下错误:

ERROR 18:49:20,883 Fatal configuration error

        at org.apache.cassandra.net.MessagingService.getServerSocket(MessagingService.java:410)

请注意,如果服务器加密选项设置为无,则服务器运行时不会出现问题.任何想法/指导将不胜感激.

仔细阅读例外情况:

引起:java.io.FileNotFoundException:conf\truststore\dev
(系统找不到指定的路径)

您已经创建了密钥/信任存储,但是您没有将cassandra指向它们.在cassandra.yaml中,您需要启用SSL,但您还需要指定这两个文件的路径.例如:

server_encryption_options:
    internode_encryption: all
    keystore: C:\some\location
    keystore_password: password
    truststore: C:\some\other\location
    truststore_password: password

还记得在cassandra.yaml中提供密钥/信任存储密码而不是示例.
