Kafka配置SASL认证密码登录

​​​​​​1、修改config/server.properties，添加如下内容

listeners=SASL_PLAINTEXT://内网ip:9092
advertised.listeners=SASL_PLAINTEXT://外网ip:9092
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN

2、添加相关安全认证配置文件

在config目录下添加kafka-zk-jaas.conf

zookeeper {org.apache.kafka.common.security.plain.PlainLoginModule requiredusername="admin"password="xxxxxx";
};

在config目录下添加kafka-server-jaas.conf

KafkaServer {org.apache.kafka.common.security.plain.PlainLoginModule requiredusername="admin"password="xxxxxx"user_admin="xxxxxx";
};

在config目录下添加kafka-client-jaas.conf

KafkaClient {org.apache.kafka.common.security.plain.PlainLoginModule requiredusername="admin"password="xxxxxx";
};

3、修改相关启动文件应用上面添加的配置文件去启动

修改zookeeper-server-start.sh，在exec前一行添加：

export KAFKA_OPTS="-Djava.security.auth.login.config=file:$base_dir/../config/kafka-zk-jaas.conf"

修改kafka-server-start.sh，在exec前一行添加：

export KAFKA_OPTS="-Djava.security.auth.login.config=file:$base_dir/../config/kafka-server-jaas.conf"

修改kafka-console-consumer.sh，在exec前一行添加：

export KAFKA_OPTS="-Djava.security.auth.login.config=file:$(dirname $0)/../config/kafka-client-jaas.conf"

修改kafka-console-producer.sh，在exec前一行添加：

export KAFKA_OPTS="-Djava.security.auth.login.config=file:$(dirname $0)/../config/kafka-client-jaas.conf"

4、修改springboot配置

spring.kafka.bootstrap-servers=外网ip:9092
spring.kafka.properties.security.protocol=SASL_PLAINTEXT
spring.kafka.properties.sasl.mechanism=PLAIN
spring.kafka.properties.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="admin" password="xxxxxx";
spring.kafka.consumer.properties.sasl.mechanism=PLAIN
spring.kafka.consumer.properties.security.protocol=SASL_PLAINTEXT

5、kafka启动停止命令

切换到kafka安装目录：cd /home/kafka_2.13-2.6.0/

zookeeper启动命令：./bin/zookeeper-server-start.sh -daemon config/zookeeper.properties

kafka启动命令：./bin/kafka-server-start.sh -daemon config/server.properties

kafka停止命令：./bin/kafka-server-stop.sh

zookeeper停止命令：./bin/zookeeper-server-stop.sh

查看zookeeper是否启动成功：ps -ef | grep zookeeper

查看kafka是否启动成功：ps -ef | grep kafka
