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。
