背景这里kafka使用的是单独部署的zookeeper 需要走认证配置

我这里使用的zookeeper版本是3.8.3 kafka 3.4.0

kafka安装目录：/usr/local/bin/xx/kafka

zookeeper安装目录：/usr/local/bin/xx/zookeeper

1. 修改配置文件
   1. 找到kafka的/usr/local/bin/xx/kafka/config/server.properties文件
   2. 修改配置

      1.KAFKA:
      在server.properties 调整
      改动之前：
      listeners=SASL_PLAINTEXT://0.0.0.0:9092
      advertised.listeners=SASL_PLAINTEXT://x.x.x.x:9092
      改动之后：
      listeners=SASL_PLAINTEXT://0.0.0.0:9092
      advertised.listeners=SASL_PLAINTEXT://x.x.x.x:9092
      security.inter.broker.protocol=SASL_PLAINTEXT  
      sasl.enabled.mechanisms=PLAIN  
      sasl.mechanism.inter.broker.protocol=PLAIN  
      authorizer.class.name=kafka.security.authorizer.AclAuthorizer
      allow.everyone.if.no.acl.found=true
      zookeeper.client.sasl=true
      2.ZOOKEEPER:
      直接在zoo.cfg 最后增加authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider
      requireClientAuthScheme=sasl
      jaasLoginRenew=3600000

2. 增加认证jaas.conf文件

   1. 1.在kafka安装目录创建文件/usr/local/bin/xx/kafka/config/
      touch kafka_server_jaas.conf
      内容如下：
      KafkaServer {org.apache.kafka.common.security.plain.PlainLoginModule requiredusername="admin"password="xx"user_admin="xx"user_kafka="xx";
      };Client {org.apache.kafka.common.security.plain.PlainLoginModule requiredusername="kafka"password="xx";
      };KafkaClient {org.apache.kafka.common.security.plain.PlainLoginModule requiredusername="kafka"password="xx";
      };
      2.在zookeeper安装目录创建文件/usr/local/bin/xx/zookeeper/conf/
      touch zk_server_jaas.conf
      内容如下：
      Server {org.apache.kafka.common.security.plain.PlainLoginModule required username="admin" password="xx" user_kafka="xx";
      };
      ps：这里创建了两个账户 admin和kafka3.全部设置完毕，重启zookeeper和kafka

3. 消费验证

   1. 1.在kafka安装目录的config目录下创建鉴权文件
      cd /usr/local/bin/xx/kafka/config
      touch sasl.config
      内容如下：
      security.protocol=SASL_PLAINTEXT sasl.mechanism=PLAIN sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="kafka" password="xx";2.启动消费者
      /usr/local/bin/xx/kafka/bin/kafka-console-consumer.sh --bootstrap-server 127.0.0.1:9092 --topic test -consumer.config /usr/local/bin/xx/kafka/config/sasl.config
      3.启动生产者
      /usr/local/bin/cscmc/app/kafka/bin/kafka-console-producer.sh --broker-list 127.0.0.1:9092 --topic test -producer.config /usr/local/bin/xx/kafka/config/sasl.config
      4.自产自消能够成功说明配置全部正确
      

4. 注意事项
   1. 单独部署的zookeeper 开启认证缺少依赖包，直接将kafka/libs下的kafka-client和lz4-java拷贝到zookeeer/lib下
   2. 新版本的kafka配置文件的类有更改由authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer --> kafka.security.authorizer.AclAuthorizer
