在 Apache Kafka 中启动多个代理时出错 -

Question

我是 Apache Kafka 的菜鸟。我正在阅读《Apache Kafka 快速入门指南》一书，并按照其步骤配置环境。所以，我开始成功地使用 Confluent 平台（Kafka 加 Zookeeper）。接下来我正在尝试初始化多个代理，但是当 broker.id= 2 启动时出现错误。我做了以下步骤：

1 - 我创建了一个名为 config/server.properties 的文件夹
mark-1.properties 和 mark-2.properties

2 - 接下来，我已经在 mark-1.properties 中写了和
mark-2.properties：

    broker.id=1
    port=9093
    log.dirs=/tmp/mark-1-logs

    broker.id=2
    port=9094
    log.dirs=/tmp/mark-2-logs

3 - Confluent 已经运行，我输入了命令 - 行：

    ./bin/kafka-server-start ./mark/mark-1.properties &

     and in other command line window

    ./bin/kafka-server-start ./mark/mark-2.properties &

输出错误是：

    [2019-06-28 00:35:26,535] ERROR Fatal error during KafkaServer     
    startup. Prepare to shutdown (kafka.server.KafkaServer)
    kafka.common.InconsistentBrokerIdException: Configured broker.id 2     
    doesn't match stored broker.id 1 in meta.properties. If you moved 
    your data, make sure your configured broker.id matches. If you 
    intend to create a new broker, you should remove all data in your 
    data directories (log.dirs).

我已按照本书和论坛的所有说明进行操作，但出现错误 坚持。我能做什么？

我希望多个代理独立运行。

Answer 1

您是从同一个./bin/Kafka-server-start 文件开始的吗？

如果是这样，您应该将所有 kafka 文件复制到另一个目录。

在同一个启动目录下，不能指定只不同的配置文件启动kafka。

Answer 2

亲爱的，错误是我的。我在新的 kafka 代理配置属性中使用有关 port 和 log.dir 的命令编写行重复。

感谢您的关注！

在正确配置文件的 sn-p 下方：

Answer 3

当我尝试在本地 Windows 机器上运行 kafka（单个 zookeeper 和单个代理）时，我遇到了这个错误 - kafka.common.InconsistentBrokerIdException。

以下更改对我有用 -

在zookeeper.properties设置-

dataDir=C:/Kafka/data/zookeeperlogs

在server.properties设置-

log.dirs=C:/Kafka/data/brokerlogs

父目录（C:/Kafka/data）以前不同，这造成了不同。
