一、错误

报的错：
ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
kafka.common.InconsistentBrokerIdException: Configured broker.id 0 doesn’t match stored broker.id Some(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).
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、错误原因

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。

起因是这样的：由于误删除了linux上的文件，以至于cd这样的命令都无法使用，幸亏还有其他的节点可以使用，经过一番倒腾后，成功的运行了zookeeper，然而运行kafka的时候，报错了ERROR Fatal error during KafkaServer startup. Prepare to shutdown ，错误提示如下的第一行。

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。
这是我修改之后，原本是broker.id=1

三、系统提示

四、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。
