记录：

zookeeper启动命令：

[root@master-yzjgxh2571705819-1651919082731-99-0727183 bin]# ./zkServer.sh start
[root@master-yzjgxh2571705819-1651919082731-99-0727183 bin]# ./zkServer.sh stop

kafka启动命令：

/data/program/kafka2.12/bin/kafka-server-start.sh /data/program/kafka2.12/config/server.properties

创建SCRAM证书

1）创建broker建通信用户：admin(在使用sasl之前必须先创建,否则启动报错)

bin/kafka-configs.sh --zookeeper 127.0.0.1:2181 --alter 
--add-config 'SCRAM-SHA-256=[password=admin-sec],
SCRAM-SHA-512=[password=admin-sec]' --entity-type users --entity-name admin

2）创建生产用户：producer

bin/kafka-configs.sh --zookeeper 127.0.0.1:2181 --alter 
--add-config 'SCRAM-SHA-256=[iterations=8192,password=prod-sec],
SCRAM-SHA-512=[password=prod-sec]' --entity-type users --entity-name producer

 3）创建消费用户：consumer

bin/kafka-configs.sh --zookeeper 127.0.0.1:2181 --alter 
--add-config 'SCRAM-SHA-256=[iterations=8192,password=cons-sec],
SCRAM-SHA-512=[password=cons-sec]' --entity-type users --entity-name consumer

SCRAM-SHA-256/SCRAM-SHA-512是对密码加密的算法，二者有其一即可

查看SCRAM证书

bin/kafka-configs.sh --zookeeper localhost:2181 --describe --entity-type users --entity-name consumer
bin/kafka-configs.sh --zookeeper localhost:2181 --describe --entity-type users --entity-name producer

服务端配置

1）创建JAAS文件

vi config/kafka_server_jaas.conf

 内容：

 KafkaServer {
org.apache.kafka.common.security.scram.ScramLoginModule required
username="admin"
password="admin-sec";
};

2）将JAAS配置文件位置作为JVM参数传递给每个Kafka Broker【bin/kafka-server-start.sh】添加

exec $base_dir/kafka-run-class.sh 
$EXTRA_ARGS -Djava.security.auth.login.config
=/home/test/kiki/kafka/ka/config/kafka_server_jaas.conf kafka.Kafka "$@"

操作：

vi bin/kafka-server-start.sh 

 修改最后一行

#exec $base_dir/kafka-run-class.sh $EXTRA_ARGS kafka.Kafka "$@"
exec $base_dir/kafka-run-class.sh $EXTRA_ARGS -Djava.security.auth.login.config=/data/program/kafka2.12/config/kafka_server_jaas.conf kafka.Kafka "$@"

3）配置server.properties【config/server.properties】

#认证配置
listeners=SASL_PLAINTEXT://:9092
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=SCRAM-SHA-256
sasl.enabled.mechanisms=SCRAM-SHA-256
#ACL配置
allow.everyone.if.no.acl.found=false
super.users=User:admin
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer

当前测试kafka端口为8100

 vi config/server.properties 

#listeners=PLAINTEXT://:8100

listeners=SASL_PLAINTEXT://:8100
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=SCRAM-SHA-512
sasl.enabled.mechanisms=SCRAM-SHA-512

advertised.listeners=SASL_PLAINTEXT://183.56.218.28:8100

#ACL配置
allow.everyone.if.no.acl.found=false
super.users=User:admin
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer

个人备注：

log.dirs=/data/program/kafka2.12/data

zookeeper.connect=183.56.218.28:2181

SCRAM-SHA-512与SCRAM-SHA-216可互相更改，看需要什么类型。PLAINTEXT为不需要认证

4）重启Kafka和Zookeeper

客户端配置

 1）为我们创建的三个用户分别创建三个JAAS文件:分别命名为
kafka_client_scram_admin_jaas.conf
kafka_client_scram_producer_jaas.conf
kafka_client_scram_consumer_jaas.conf

vi config/kafka_client_scram_admin_jaas.conf

KafkaClient { org.apache.kafka.common.security.scram.ScramLoginModule required username="admin" password="admin-sec"; };

vi config/kafka_client_scram_producer_jaas.conf

KafkaClient { org.apache.kafka.common.security.scram.ScramLoginModule required username="producer" password="prod-sec"; };

vi config/kafka_client_scram_consumer_jaas.conf

KafkaClient { org.apache.kafka.common.security.scram.ScramLoginModule required username="consumer" password="cons-sec"; };

2）修改启动脚本引入JAAS文件：
生产者配置：
配置bin/kafka-console-producer.sh

#exec $(dirname $0)/kafka-run-class.sh kafka.tools.ConsoleProducer "$@"

exec $(dirname $0)/kafka-run-class.sh 
-Djava.security.auth.login.config
=/data/program/kafka2.12/config/kafka_client_scram_producer_jaas.conf

消费者配置：
配置bin/kafka-console-consumer.sh

#exec $(dirname $0)/kafka-run-class.sh kafka.tools.ConsoleConsumer "$@"

exec $(dirname $0)/kafka-run-class.sh 
-Djava.security.auth.login.config
=/data/program/kafka2.12/config/kafka_client_scram_consumer_jaas.conf

3)配置consumer.properties和producer.properties,都要加入以下配置

security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-512

4）创建主题

[test@police ka]$ bin/kafka-topics.sh --zookeeper localhost:2181 --create --topic test --partitions 2 --replication-factor 1

5)启动生产(ps:结束也未能成功测试该命令是否能用,后面在代码方面配置就好)

bin/kafka-console-producer.sh --broker-list 127.0.0.1:9092 --topic test --producer.config config/producer.properties

发现会报权限相关的错

6）对生产者赋予写的权限

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer
--authorizer-properties zookeeper.connect=localhost:2181 --add
 --allow-principal User:producer --operation Write --topic test

7)对消费者赋予读的权限

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer
--authorizer-properties zookeeper.connect=localhost:2181 --add
 --allow-principal User:consumer --operation Read --topic test

此时启动消费者(ps:结束也未能成功测试该命令是否能用,后面在代码方面配置就好)

bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning --consumer.config config/consumer.properties

此时依旧会报错，报未对消费者组授权。给groupId配权

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer
--authorizer-properties zookeeper.connect=localhost:2181 --add 
--allow-principal User:consumer --operation Read --group test-group

此时再启动消费者，可以发现能正常消费生产者的消息

8）查看权限

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer 
--authorizer-properties zookeeper.connect=localhost:2181 --list

springboot整合配置

权限主要配置部分格式：

      props.put("security.protocol", "SASL_PLAINTEXT");
      props.put("sasl.mechanism", "SCRAM-SHA-512");
      props.put("sasl.jaas.config",
            "org.apache.kafka.common.security.scram.ScramLoginModule required username='easy' password='easy1234';");

生产者：

//异步发送
    @Test
    fun customProducer() {
        //配置
        val properties = Properties()
        //链接kafka
        properties[ProducerConfig.BOOTSTRAP_SERVERS_CONFIG] = "183.56.218.28:8100"
        //指定对应key和value的序列化类型(二选一)
//        properties[ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG] = "org.apache.kafka.common.serialization.StringSerializer"
        properties[ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG] = StringSerializer::class.java.name
        properties[ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG] = StringSerializer::class.java.name
        properties[CommonClientConfigs.SECURITY_PROTOCOL_CONFIG] = "SASL_PLAINTEXT"
        properties[SaslConfigs.SASL_MECHANISM] = "SCRAM-SHA-512"
        properties[SaslConfigs.SASL_JAAS_CONFIG] = "org.apache.kafka.common.security.scram.ScramLoginModule required username=\"producer\" password=\"prod-sec\";"
        val kafkaProducer = KafkaProducer<String, String>(properties)
        //发送数据
        for (i in 0 until 1) {
            //黏性发送，达到设置的数据最大值/时间后，切换分区（不会是当前分区）
            kafkaProducer.send(ProducerRecord("test", "我是成功:::${LocalDateTime.now()}"))
        }//"type":"UPDATE/ADD/DELETE"
        //关闭资源
        kafkaProducer.close()
    }
