kafka-报错kafka.common.InconsistentClusterIdException
一、背景
kafka的物理机意外宕机，导致kafka启动不起来
二、报错详情
[2022-08-09 08:20:42,097] ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer) kafka.common.InconsistentClusterIdException: The Cluster ID 123456 doesnt match stored clusterId Some(456789) in meta.properties. The broker is trying to join the wrong cluster. Configured zookeeper.connect may be wrong. at kafka.server.KafkaServer.startup(KafkaServer.scala:235) at kafka.server.KafkaServerStartable.startup(KafkaServerStartable.scala:44) at kafka.Kafka$.main(Kafka.scala:82) at kafka.Kafka.main(Kafka.scala)
三、解决
可以看到报错比较明显了，是cluster-id对不上了，这时候我们可以修改meta.properties的配置
# meta.properties文件的位置可以根据server.properties配置文件的log.dirs参数的值进行查找 vim meta.properties cluster.id=123456
接下来就可以正常启动了
