Question

我正在尝试为一个项目设置一个kafka服务器。我正在遵循本指南-https://kafka.apache.org/quickstart。我成功地运行了zookeper，但是当我尝试启动kafka服务器时，却出现以下错误。我尝试了不同的配置属性路径，但是得到了相同的消息。

bin\windows\zookeeper-server-start.bat C:\Users\Atanas0104\Documents\kafka_2.12-2.3.0\config\server.properties

这是错误消息

Answer 1

Mistake是您正在运行带有kafka服务器.properties的zookeeper-server-start.bat ，您需要尝试使用kafka-server-start.bat 1）首先转到kafka所在的文件夹，然后尝试

.\bin\windows\kafka-server-start.bat .\config\server.properties

Answer 2

我认为您的server.properties不好，我下载了它，但遇到了同样的情况，我只更改了

的最后一行

group.initial.rebalance.delay.ms=0

到

initial.rebalance.delay.ms=0

它确实起作用了。

启动Zookeeper后尝试启动kafka服务器，但得到错误无效的配置，异常退出
