Kafka-启动时报错: ERROR Fatal error during KafkaServer startup. Prepare to shutdown

一、问题描述

在启动kafka时报错：

ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

kafka.common.InconsistentBrokerIdException: Configured broker.id 1 doesn’t match stored broker.id Some(0) 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).

at kafka.server.KafkaServer.getOrGenerateBrokerId(KafkaServer.scala:793)

at kafka.server.KafkaServer.startup(KafkaServer.scala:221)

at kafka.Kafka$.main(Kafka.scala:109)

at kafka.Kafka.main(Kafka.scala)

 

二、问题原因

起因是这样的：由于在一个节点上启动运行了kafka后，再拷贝到其他节点上，配置kafka相关配置，在启动kafka时报错。

究其原因，是meta.properties（路径：/opt/kafka/logs）里面的id值和/opt/kafka/config的server.properties中的broker.id不一致。

 

三、解决办法

找到了原因，把broker=0和broker.id=1修改为一样的值，然后重启动，ERROR Fatal error during KafkaServer startup. Prepare to shutdown 的错误就没了。
