Kafka SASL zookeeper认证

Question

我在Zookeeper和代理身份验证上启用SASL时遇到以下错误.

以下配置在JAAS文件中给出,该文件作为KAFKA_OPTS传递,将其作为JVM参数: -

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

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

    };

kafka broker的server.properties设置了以下额外字段: -

zookeeper.set.acl=true
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN
ssl.client.auth=required
ssl.endpoint.identification.algorithm=HTTPS
ssl.keystore.location=path
ssl.keystore.password=anything
ssl.key.password=anything
ssl.truststore.location=path
ssl.truststore.password=anything

Zookeeper属性如下: -

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

我通过将日志级别增加到DEBUG来找到问题.基本上按照以下步骤.我不使用SSL,但你会毫无问题地整合它.

以下是我的配置文件:

server.properties

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
auto.create.topics.enable=false
broker.id=0
listeners=SASL_PLAINTEXT://localhost:9092
advertised.listeners=SASL_PLAINTEXT://localhost:9092
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600

advertised.host.name=localhost
num.partitions=1
num.recovery.threads.per.data.dir=1
log.flush.interval.messages=30000000
log.flush.interval.ms=1800000
log.retention.minutes=30
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
delete.topic.enable=true
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=6000
super.users=User:admin

zookeeper.properties

dataDir=/tmp/zookeeper
clientPort=2181
maxClientCnxns=0
authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider
requireClientAuthScheme=sasl
jaasLoginRenew=3600000

producer.properties

security.protocol=SASL_PLAINTEXT
sasl.mechanism=PLAIN
bootstrap.servers=localhost:9092
compression.type=none

consumer.properties

security.protocol=SASL_PLAINTEXT
sasl.mechanism=PLAIN
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=6000
group.id=test-consumer-group

现在是使您的服务器启动没有任何问题的最重要的文件:

zookeeper_jaas.conf

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

kafka_server_jaas.conf

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

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

完成所有这些配置后,在第一个终端窗口上:

1号航站楼

来自kafka根目录

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/usename/Documents/kafka_2.11-0.10.1.0/config/zookeeper_jaas.conf"
$ bin/zookeeper-server-start.sh config/zookeeper.properties

2号航站楼

来自kafka根目录

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/usename/Documents/kafka_2.11-0.10.1.0/config/kafka_server_jaas.conf"
$ bin/kafka-server-start.sh config/server.properties

[开始更新]

kafka_client_jaas.conf

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

3号航站楼

在客户端终端上,导出客户端jaas conf文件并启动使用者:

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/username/Documents/kafka_2.11-0.10.1.0/kafka_client_jaas.conf"
$ ./bin/kafka-console-consumer.sh --new-consumer --zookeeper localhost:2181 --topic test-topic --from-beginning --consumer.config=config/consumer.properties  --bootstrap-server=localhost:9092

4号航站楼

如果您还想生产,请在另一个终端窗口上执行此操作:

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/username/Documents/kafka_2.11-0.10.1.0/kafka_client_jaas.conf"
$ ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test-topic --producer.config=config/producer.properties

[END UPDATE]

Answer 2

您需要为Zookeeper创建一个JAAS配置文件并使用它。

使用以下内容为Zookeeper创建文件JAAS配置文件：

Server {
    org.apache.zookeeper.server.auth.DigestLoginModule required
    user_admin="admin-secret";
};

用户（admin）和密码（admin-secret）必须与您在Kafka JAAS配置文件的“客户端”部分中拥有的用户名和密码匹配。

要使Zookeeper使用JAAS配置文件，请将以下JVM标志传递给Zookeeper，使其指向之前创建的文件。

-Djava.security.auth.login.config=/path/to/server/jaas/file.conf"

如果您使用的是Kafka软件包随附的Zookeeper，则可以假设您的Zookeeper JAAS配置文件位于./config/zookeeper_jaas.conf中，则可以这样启动Zookeeper。

EXTRA_ARGS=-Djava.security.auth.login.config=./config/zookeeper_jaas.conf ./bin/zookeeper-server-start.sh ./config/zookeeper.properties
