Question

尝试设置Kafka SASL身份验证。

这是我的Kafka经纪人JAAS文件：

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

Zookeeper JAAS文件：

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

Kafka经纪人属性

listeners=SASL_PLAINTEXT://localhost:9092
authroizer.class.name=kafka.security.auth.SimpleAclAuthorizer
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAINTEXT
sasl.enabled.mechanisms=PLAINTEXT

Zookeeper属性：

authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider
requireClientAuthScheme=sasl
jaasLoginRenew=3600000

当我尝试启动Kafka服务器时，我不断收到此错误。

请帮助。无法理解此问题。

Kafka SASL身份验证设置错误：身份验证期间终止了与节点0（localhost / 127.0.0.1：9092）的连接
