SSL加密与Cassandra

Question

我试图启用客户端对SSL加密的节点，但是在cassandra.yaml中将client_encryption_options设置为true之后，当尝试启动DSE时，始终会遇到最奇怪的错误。

这来自dse日志：

ERROR 15:09:42,277  DseModule.java:108 - Unable to start server. Exiting...
com.google.inject.CreationException: Unable to create injector, see the following errors:

这是我的cassandra.yaml文件

client_encryption_options:
    enabled: false
    # If enabled and optional is set to true encrypted and unencrypted connections are handled.
    optional: false
    keystore: /home/ec2-user/keystore.node2
    keystore_password: cassandra
    require_client_auth: true
    # Set trustore and truststore_password if require_client_auth is true
    truststore: /home/ec2-user/truststore.node2
    truststore_password: cassandra
    # More advanced defaults below:
    protocol: TLS
    algorithm: SunX509
    store_type: JKS
    cipher_suites: [TLS_RSA_WITH_AES_256_CBC_SHA]

我不知道为什么我总是

SSLContext: File '/home/ec2-user/keystore.node2' does not exist

这是我的密钥库的位置-

[ec2-user@ip-172-18-51-175 ~]$ locate keystore.node2
/home/ec2-user/keystore.node2

我到底做错什么了？

Answer 1

切换到您的cassandra用户，并执行cat /home/ec2-user/keystore.node2并查看该用户是否可以看到该文件

还可以运行：ls -lna /home/ec2-user/keystore.node2和post。
