问题描述：

本来kafka有三个节点，云主机异常使得两个节点kafka服务所在的磁盘丢失，现在恢复集群，拷贝未丢失节点的kafka服务目录到新恢复的节点，但是在启动服务时报错，如下所示：

$ /data/opt/kafka_2.12-0.10.2.1/bin/kafka-server-start.sh /data/opt/kafka_2.12-0.10.2.1/config/server.properties

[2019-01-08 16:24:59,300] FATAL Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

kafka.common.InconsistentBrokerIdException: Configured broker.id 0 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).

配置文件server.properties的配置都有做修改，三个节点分别是0、1、2，出错的节点配置如下

$ vi /data/opt/kafka_2.12-0.10.2.1/config/server.properties

broker.id=0

根据提示找到meta.properties文件，修改broker.id和server.properties的该配置参数一致

$ vi /data/opt/kafka_2.12-0.10.2.1/logs/meta.properties

broker.id=1

>> 

broker.id=0

启动服务正常
