java - Cassandra:如何设置客户端到节点的加密？

Question

我已经使用 DataStax guide 设置了 Cassandra 客户端到节点的加密

来自 cassandra.yaml 文件的 Client_encription_options:

 client_encryption_options:
    enabled: true
    keystore: /opt/key/.keystore
    keystore_password: cassandra
    cipher_suites:[TLS_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA]        

客户端使用 SSL 的默认 Java 系统属性:

-Djavax.net.ssl.trustStore=/opt/app/conf/.truststore -Djavax.net.ssl.trustStorePassword=cassandra    

但是连接后在 Cassandra 日志中出现错误:

INFO [Native-Transport-Requests:12] 2015-02-11 11:45:52,456 Message.java (line 397) Unexpected exception during request; channel = [id: 0xfb3df0e3, /192.168.43.13:32885 => /192.168.43.10:9042]

我使用的是 Cassandra 2.0.10.71，Java 1.7.0_75 和 Java 加密扩展库

这是一条信息消息，表明已为您的 Cassandra 节点设置了无 ssl 包。似乎有东西试图连接到您的 Cassandra 节点。

查看引发异常的 Netty java 文件的源代码。 org.jboss.netty.handler.ssl.SslHandler.decode(SslHandler.java:871)

  if (nonSslRecord) {
       // Not an SSL/TLS packet
        NotSslRecordException e = new NotSslRecordException(
        "not an SSL/TLS record: " + ByteBufUtil.hexDump(in));
        in.skipBytes(in.readableBytes());
            ctx.fireExceptionCaught(e);
            setHandshakeFailure(ctx, e);
   }
