首先启动 zookeeper
/home/kafka/bin/zookeeper-server-start.sh /home/kafka/config/zookeeper.properties
创建SCRAM证书
/home/kafka/bin/kafka-configs.sh --zookeeper localhost:2181 --alter --add-config SCRAM-SHA-256=[iterations=8192,password=liebe],SCRAM-SHA-512=[password=liebe] --entity-type users --entity-name liebe
/home/kafka/bin/kafka-configs.sh --zookeeper 127.0.0.1:2181 --alter --add-config SCRAM-SHA-256=[password=admin],SCRAM-SHA-512=[password=admin] --entity-type users --entity-name admin
证书查看
/home/kafka/bin/kafka-configs.sh --zookeeper localhost:2181 --describe --entity-type users --entity-name admin
证书删除
/home/kafka/bin/kafka-configs.sh --zookeeper localhost:2181 --alter --delete-config SCRAM-SHA-512 --delete-config SCRAM-SHA-256 --entity-type users --entity-name liebe
服务端配置
在 kafka 配置文件目录 config 创建文件 kafka-server-jass.conf，如我的目录是：/home/kafka/config
文件内容为：
KafkaServer {
org.apache.kafka.common.security.scram.ScramLoginModule required
username="admin"
password="admin";
};
kafka-run-class.sh文件追加内容
# Generic jvm settings you want to add
if [ -z "$KAFKA_OPTS" ]; then
KAFKA_OPTS="-Djava.security.auth.login.config=/home/kafka/config/kafka-server-jass.conf"
fi
/home/kafka/config/server.properties设置配置

/home/kafka/config/producer.properties
/home/kafka/config/consumer.properties
/home/kafka/config/auth.conf
将下面的内容追加到producer.properties和consumer.properties,并创建auth.conf文件
security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="admin" password="admin";
启动kafka
/home/kafka/bin/kafka-server-start.sh /home/kafka/config/server.properties
创建topic命令
/home/kafka/bin/kafka-topics.sh --bootstrap-server localhost:9092 --create --partitions 1 --replication-factor 1 --topic test --command-config /home/kafka/config/auth.conf
发送消息
/home/kafka/bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test --producer.config /home/kafka/config/auth.conf
控制台监听消费消息
/home/kafka/bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning --consumer.config /home/kafka/config/auth.conf
