全网最详细的启动Kafka服务时出现kafka.common.InconsistentBrokerIdException: Configured brokerId 3 doesn't match stored brokerId 1 in meta.properties错误的解决办法（图文详解）

　　不多说，直接上干货！

　问题详情

　　　　执行bin/kafka-server-start.sh config/server.properties 时，

[kfk@bigdata-pro03 kafka_2.-0.9.0.0]$ bin/kafka-server-start.sh config/server.properties

　　问题分析

　　　　一般都是，你自己修改了kafka版本之间切换造成的。你之前，是用kafka0.8.X系列，现在你升级使用0.9.X。没有完全更改过来。

　　　　解决办法：

　　找到配置文件

　　cat server.properties

　　查看log.dirs所在位置

　　log.dirs=/opt/modules/kafka_2.11-0.9.0.0/kafka-logs

　　按着这个路径找到

　　meta.properties

　　修改brokerid

[kfk@bigdata-pro03 kafka-logs]$ cat meta.properties
