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

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 # #Sun Jun 17 15:59:31 CST 2018 version=0 broker.id=1 [kfk@bigdata-pro03 kafka-logs]$ pwd /opt/modules/kafka_2.11-0.9.0.0/kafka-logs [kfk@bigdata-pro03 kafka-logs]$ vim meta.properties
