Kafka身份验证 生产环境 者无法连接 生产环境 者

我尝试复制描述的SASL_PLAIN或SASL_SSL身份验证：http://docs.confluent.io/3.0.0/kafka/sasl.html#sasl-configuration-for-kafka-brokers

在config / server.properties中，我添加了以下4行：

listeners=SASL_SSL://localhost:9092
security.inter.broker.protocol=SASL_SSL
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN

在config / producer.properties中，我添加了以下两行：

security.protocol=SASL_SSL
sasl.mechanism=PLAIN

然后我在服务器终端中设置以下环境变量：

KAFKA_OPTS=/home/kafka/kafka_server_jaas.conf

该文件包含以下内容：

KafkaServer {
   org.apache.kafka.common.security.plain.PlainLoginModule required
   username="admin"
   password="admin-secret"
   user_admin="admin-secret"
   user_alice="alice-secret";
};

在 生产环境 者终端中，我定义了以下env变量：

KAFKA_OPTS=/home/kafka/kafka_client_jaas.conf

此文件包含以下内容：

KafkaClient {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="alice"
  password="alice-dsecret";
};

我使用以下命令启动服务器：

./bin/kafka-server-start.sh   config/server.properties

并且生成器具有以下命令：

bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test

两者都没有问题 . 但是，只要我在 生产环境 者控制台上键入内容，我就会收到以下消息：

WARN Bootstrap broker localhost:9092 disconnected (org.apache.kafka.clients.NetworkClient)
Bootstrap broker localhost:9092 disconnected (org.apache.kafka.clients.NetworkClient)
WARN Bootstrap broker localhost:9092 disconnected (org.apache.kafka.clients.NetworkClient)
WARN Bootstrap broker localhost:9092 disconnected (org.apache.kafka.clients.NetworkClient)
WARN Bootstrap broker localhost:9092 disconnected (org.apache.kafka.clients.NetworkClient)
WARN Bootstrap broker localhost:9092 disconnected (org.apache.kafka.clients.NetworkClient)
WARN Bootstrap broker localhost:9092 disconnected (org.apache.kafka.clients.NetworkClient)
WARN Bootstrap broker localhost:9092 disconnected (org.apache.kafka.clients.NetworkClient)

如果我从服务器和 生产环境 者配置中删除安全配置，一切都按预期工作 . 我正在使用Kafka 0.10.0.1 .

更新：我做了一些调查，在服务器上将日志级别转换为DEBUG显示出一些奇怪的东西 . 一旦我在server.properties中指定了listeners字段，服务器就会进入奇怪的状态 . 它 Build 了与自身无法进行身份验证的连接 . 这种情况下的协议是SASL_PLAINTEXT .

日志如下：

绝对没有其他客户端或服务器在运行 . 这是一个与自己交谈的服务器 .

有什么想法吗？
