注意事项

  1. topic __consumer_offsets 需要多个副本，否则一个副本那台机器挂了，kafka集群就会停摆
  2. kafka hostname映射ip 每台机器都需要同步， 包括消费者和生产者机器
kafka1 x.x.x.x
kafka2 x.x.x.x
kafka3 x.x.x.x
kafka4 x.x.x.x
kafka5 x.x.x.x
  1. KAFKA_CFG_NUM_PARTITIONS=3和KAFKA_CFG_OFFSETS_TOPIC_REPLICATION_FACTOR=3 参数不能大于集群台数
  2. 参数解释
这些参数是用于配置和设置 Apache Kafka 的各种属性和功能。下面是对每个参数的解释：
  
   KAFKA_ADVERTISED_HOST_NAME: 这是 Kafka 服务器的主机名或 IP
   地址，用于通知生产者和消费者连接到该地址。
   
   KAFKA_ENABLE_KRAFT: 这个参数启用 Kafka Raft（KRaft）模式，它是 Kafka 2.8.0
   版本引入的一种新的高可用性模式。
   
   KAFKA_KRAFT_CLUSTER_ID: 这是 KRaft 集群的唯一标识符，用于将 Kafka 服务器加入特定的 KRaft
   集群。
   
   KAFKA_CFG_PROCESS_ROLES: 这个参数指定 Kafka 服务器的角色，其中 "broker" 表示服务器是一个普通的
   Kafka 节点，"controller" 表示服务器是集群的控制器。
   
   KAFKA_BROKER_ID: 这是 Kafka 服务器的唯一标识符，用于在集群中区分不同的服务器。
   
   KAFKA_CFG_NUM_PARTITIONS: 这个参数指定每个主题的默认分区数。分区是 Kafka
   中的消息存储单元，用于实现消息的并行处理。
   
   KAFKA_CFG_OFFSETS_TOPIC_REPLICATION_FACTOR:
   这个参数指定偏移量主题的副本因子，偏移量主题用于存储消费者的偏移量信息。
   
   KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP:
   这个参数定义了不同监听器的安全协议映射关系。在这个例子中，"CLIENT"、"EXTERNAL" 和 "CONTROLLER"
   分别映射到 "PLAINTEXT" 协议，表示这些监听器使用明文传输。
   
   KAFKA_CFG_LISTENERS: 这个参数定义了 Kafka
   监听器的配置。在这个例子中，有三个监听器分别使用不同的协议和端口号。
   
   KAFKA_CFG_ADVERTISED_LISTENERS: 这个参数指定了广告监听器的配置，用于告知生产者和消费者连接到 Kafka
   的地址和端口号。
   
   KAFKA_CFG_INTER_BROKER_LISTENER_NAME: 这个参数指定了经纪人之间通信使用的监听器名称，其中
   "CLIENT" 表示使用客户端监听器。
   
   KAFKA_CFG_CONTROLLER_LISTENER_NAMES:
   这个参数指定控制器监听器的名称，用于控制器与其他经纪人之间的通信。
   
   KAFKA_CFG_CONTROLLER_QUORUM_VOTERS: 这个参数指定了控制器选举过程中的投票者信息，包括其 ID
   和监听器的地址。
   
   ALLOW_PLAINTEXT_LISTENER: 这个参数允许使用明文传输的监听器进行连接。
   
   KAFKA_AUTO_CREATE_TOPICS_ENABLE:
   这个参数启用自动创建主题的功能，当生产者发送消息到不存在的主题时，将自动创建该主题。
   
   KAFKA_CFG_INITIAL_BROKER_REGISTRATION_TIMEOUT_MS:
   这个参数指定初始经纪人注册的超时时间，以毫秒为单位。在集群启动期间，经纪人必须在指定的时间内完成注册。
   
   这些参数可以根据实际需求进行配置和调整，以满足特定的 Kafka 集群设置和功能要求。
