Kafka配置SASL_PLAINTEXT权限。常用操作命令，创建用户，topic授权

news 2025/9/14 5:10:56

查看已经创建的topic

./bin/kafka-topics.sh --bootstrap-server localhost:9092 --list

创建topic

创建分区和副本数为1的topic

./bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --topic acltest --partitions 1 --replication-factor 1

创建kafka用户

创建writer用户

./bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter -add-config 'SCRAM-SHA-256=[iterations=8192,password=pwd],SCRAM-SHA-512=[password=pwd]' --entity-type users --entity-name kafkawriter

创建reader用户

./bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter -add-config 'SCRAM-SHA-256=[iterations=8192,password=pwd],SCRAM-SHA-512=[password=pwd]' --entity-type users --entity-name kafkareader

删除指定用户

./bin/kafka-configs.sh --zookeeper localhost:2181 --alter --delete-config 'SCRAM-SHA-512' --delete-config 'SCRAM-SHA-256' --entity-type users --entity-name admin

查看指定用户

./bin/kafka-configs.sh --bootstrap-server localhost:9092 --describe --entity-type users --entity-name kafkawriter

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

给topic授权

./bin/kafka-acls.sh --authorizer kafka.security.authorizer.AclAuthorizer --authorizer-properties zookeeper.connect=192.168.5.54:2181 --add --allow-principal User:kafkawriter --operation Write --topic bigData

查看topic权限

./bin/kafka-acls.sh --authorizer kafka.security.authorizer.AclAuthorizer --authorizer-properties zookeeper.connect=192.168.5.54:2181 --list --topic bigData

修改server.properties，开启sasl

listeners=SASL_PLAINTEXT://192.168.1.214:9092

advertised.listeners=SASL_PLAINTEXT://192.168.1.214:9092

authorizer.class.name=kafka.security.authorizer.AclAuthorizer

allow.everyone.if.no.acl.found=false

super.users=User:admin

# 启用SCRAM机制，采用SCRAM-SHA-512算法

sasl.enabled.mechanisms=SCRAM-SHA-256

# 为broker间通讯开启SCRAM机制，采用SCRAM-SHA-512算法

sasl.mechanism.inter.broker.protocol=SCRAM-SHA-256

# broker间通讯使用PLAINTEXT，本例中不演示SSL配置

security.inter.broker.protocol=SASL_PLAINTEXT

重启kafka服务

新建生产者配置

config/producer.conf

security.protocol=SASL_PLAINTEXT

sasl.mechanism=SCRAM-SHA-256

sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="kafkawriter" password="pwd";

给生产者授权

./bin/kafka-acls.sh --authorizer kafka.security.authorizer.AclAuthorizer --authorizer-properties zookeeper.connect=192.168.1.214:2181 --add --allow-principal User:kafkawriter --operation Write --topic bigData

生产者发送消息

./bin/kafka-console-producer.sh --broker-list 192.168.1.214:9092 --topic bigData --producer.config ./config/producer.conf

新建消费者配置

security.protocol=SASL_PLAINTEXT

sasl.mechanism=SCRAM-SHA-256

sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="kafkareader" password="pwd";

cat config/producer.conf

给消费者授权

授权group分组

消费者消费消息

./bin/kafka-console-consumer.sh --bootstrap-server 192.168.1.214:9092 --topic bigData --consumer.config ./config/consumer.conf --from-beginning --group testgroup
