Question

我在AWS中安装了多区域配置中的Datastax enterprise 4.5.3和Opscenter 5.0.1。我试图通过启用节点到节点加密，客户端到节点加密以及opscenter和代理之间的ssl来尽可能地保证通信安全。

启用客户端到节点加密后，我遇到代理问题。在casssandra.yaml中启用加密后，datastax代理会抛出一条错误消息，指出它无法连接到群集。

cassandra.yaml的一部分：

# enable or disable client/server encryption.
client_encryption_options:
    enabled: true
    keystore: /usr/share/dse/resources/dse/conf/.keystore
    keystore_password: supersecret_password
    # require_client_auth: false
    # Set trustore and truststore_password if require_client_auth is true
    truststore: /usr/share/dse/resources/dse/conf/.truststore
    truststore_password: supersecret_password
    # More advanced defaults below:
    protocol: SSL
    # algorithm: SunX509
    # store_type: JKS
    # cipher_suites [TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA]

在cassandra.yaml中启用客户端到节点加密后，代理无法连接到群集。在/var/log/datastax-agent/agent.log中，我反复看到这个错误：

请确保您已在 address.yaml 中完成了代理配置。它应该设置如下：

stomp_interface: <stomp_interface_ip of opscenterd box>
local_interface: <broadcast or listen_address_ip in cassandra.yaml>
cassandra_conf: "<path>/dse-4.5.1/resources/cassandra/conf/cassandra.yaml"
use_ssl: 1
ssl_keystore: <path to keystore>/.keystore
ssl_keystore_password: <ks password>
thrift_ssl_truststore: <path to truststore>/.truststore
thrift_ssl_truststore_password: <ts password>
hosts: ["<ip address>"]

请参阅此处针对tarball安装的SSL和Opscenter的其他详细配置步骤，此处查看package安装
