无法使用 SASL_PLAINTEXT 身份验证启动 Kafka 服务器

Question

我正在尝试使用以下配置在 Windows Server 2016 上运行 Apache Kafka

server.propertiers：

delete.topic.enable=true
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer
allow.everyone.if.no.acl.found=true
security.protocol=SASL_PLAINTEXT

listeners=SASL_PLAINTEXT://127.0.0.1:9092

advertised.listeners=SASL_PLAINTEXT://localhost:9092

listener.security.protocol.map=SASL_PLAINTEXT:SASL_PLAINTEXT

kafka_server_jaas.conf：

KafkaServer {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="username"
    password="password"
    user_kafkaadmin="password2";
};

Client {};

start-kafka.bat：

@echo off
SET KAFKA_OPTS = "-Djava.security.auth.login.config=C:\Kafka\config\kafka_server_jaas.conf"
C:\Kafka\bin\windows\kafka-server-start.bat C:\Kafka\config\server.properties

但是我收到以下错误

ERROR [KafkaServer id=0] Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

我是否在配置中遗漏了什么？

谢谢，

尝试删除等号前后的空格：

SET KAFKA_OPTS=-Djava.security.auth.login.config=C:\Kafka\config\kafka_server_jaas.conf

因为通常你不应该在等号两边加空格。等号之前的空格将成为名称的一部分；等号之后的空格将成为值的一部分。
