我正在尝试复制sasl\u平原或sasl\u ssl身份验证，描述如下：http://docs.confluent.io/3.0.0/kafka/sasl.html#sasl-Kafka经纪人配置
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

然后在服务器终端中设置以下环境变量：

KAFKA_OPTS=/home/kafka/kafka_server_jaas.conf

此文件包含以下内容：

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

在producer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

以及制作人的以下命令：

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

两个开始都没有问题。但是，只要我在producer控制台上键入一些内容，就会收到以下消息，并不断滚动：

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者配置中删除安全配置，那么一切都会按预期工作。我用的是Kafka0.10.0.1。
更新：我做了更多的调查，将日志级别改为在服务器上调试会发现一些奇怪的事情。一旦我在server.properties中指定了listeners字段，服务器就会进入一种奇怪的状态。它建立与自身的连接，但无法进行身份验证。本案中的协议是sasl d u明文协议。
日志如下：

绝对没有其他客户端或服务器在运行。这是一个服务器在自言自语。
有什么想法吗？
