Docker部署Kafka集群，增加 SASL_SSL认证，并集成到Spring Boot，无Zookeeper版

1，准备好Kafka 镜像包：

bitnami/kafka:3.9.0 镜像资源包

2，准备好kafka.keystore.jks 和 kafka.truststore.jks证书

具体操作可参考：

Docker部署Kafka SASL_SSL认证，并集成到Spring Boot-CSDN博客

3，配置文件 docker-compose.yml

配置中使用的IP 1.14.165.18为主机IP，需要更换，提供外部访问

注意1.14.165.18要替换成主机IP

    volumes:

      - './kafka.keystore.jks:/opt/bitnami/kafka/config/certs/kafka.keystore.jks:ro'
      - './kafka.truststore.jks:/opt/bitnami/kafka/config/certs/kafka.truststore.jks:ro'
    networks:
      - kafka-net
networks:
  kafka-net:
    driver: bridge

4，创建数据挂载目录

bash 复制代码

sudo mkdir -p /data/kafka/kafka_1_data /data/kafka/kafka_2_data /data/kafka/kafka_3_data
sudo chmod 777 /data/kafka/*

5，启动服务

在 kafka-cluster 目录中运行以下命令来启动 Kafka 集群：

bash 复制代码

sudo docker-compose up -d

6，测试验证：

在容器修改producer.properties和consumer.properties

增加以下参数：

具体操作可查看上篇文章

ssl.endpoint.identification.algorithm=

producer.ssl.endpoint.identification.algorithm=

consumer.ssl.endpoint.identification.algorithm=

注意1.14.165.18要替换成主机IP

测试发送消息：

bash 复制代码

sudo docker exec -it kafka1 kafka-console-producer.sh --bootstrap-server 1.14.165.18:9092 --topic test --producer.config /opt/bitnami/kafka/config/producer.properties

测试接收消息：

bash 复制代码

sudo docker exec -it kafka1 kafka-console-consumer.sh --bootstrap-server 1.14.165.18:9092 --topic test --consumer.config /opt/bitnami/kafka/config/consumer.properties

10，使用Spring Boot 集成Kafka集群

添加pom依赖：

XML 复制代码

    <dependency>
      <groupId>org.springframework.kafka</groupId>
      <artifactId>spring-kafka</artifactId>
    </dependency>

配置application.yml，并修改对应服务IP地址

注意1.14.165.18要替换成Kafka服务器IP

java 复制代码

spring:
  application:
    name: ncc
  kafka:
    bootstrap-servers:
      - 1.14.165.18:9092
      - 1.14.165.18:9093
      - 1.14.165.18:9094
    properties:
      security.protocol: SASL_SSL
      sasl.mechanism: SCRAM-SHA-512
      sasl.jaas.config: org.apache.kafka.common.security.scram.ScramLoginModule required username="kafka" password="kafka2024";
      ssl.truststore.location: kafka.truststore.jks
      ssl.truststore.password: kafka2024
      ssl.keystore.location: kafka.keystore.jks
      ssl.keystore.password: kafka2024
      ssl.key.password: kafka2024
      ssl.endpoint.identification.algorithm:
      producer.ssl.endpoint.identification.algorithm:
      consumer.ssl.endpoint.identification.algorithm:

并将kafka.keystore.jks 和 kafka.truststore.jks 文件放到当前项目

11，创建KafkaTest测试类

java 复制代码

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.kafka.core.KafkaTemplate;
 
@SpringBootTest(classes = NccApplication.class)
public class KafkaTest {
 
    @Autowired
    private KafkaTemplate<String, String> kafkaTemplate;
 
    @Test
    void send() {
        kafkaTemplate.send("test","hhh");
    }
 
}

测试通过
