启动多个Kafka经纪人失败 [英] Launching multiple Kafka brokers fails

问题描述

尝试启动多个具有不同brokerId的Kafka经纪人时.一个是默认的 server.properties ，另一个是 serverTest.properties ，但更改了两行，分别是 broker.id = 1 和 listeners = PLAINTEXT://localhost:6000 .其余的是相同的默认设置.我首先启动zookeeper，然后启动默认的kafka server.properties ，然后在启动 serverTest.properties 时遇到以下异常: kafka.common.InconsistentBrokerIdException:已配置的brokerId 1与meta.properties 中存储的brokerId 0不匹配.我的理解是，以上内容实际上应该启动多个节点，就像我在教程中看到的一样.我正在使用Kafka 9.0.

While trying to launch multiple Kafka brokers with different brokerId's. One being the default server.properties and the other being serverTest.properties with 2 lines changed, those being broker.id=1 and listeners=PLAINTEXT://localhost:6000. The rest is the same default setting. I first start zookeeper, then the default kafka server.properties then while launching serverTest.properties I get the following exception: kafka.common.InconsistentBrokerIdException: Configured brokerId 1 doesn't match stored brokerId 0 in meta.properties. My understanding is that the following above should actually launch multiple nodes, as I've seen others do in tutorials. I'm using Kafka 9.0.

推荐答案

编辑config/serverTest.properties并替换现有的配置值，如下所示:

Edit config/serverTest.properties and replace the existing config values as follows:

broker.id=2
port=9093
log.dir=/tmp/kafka-logs-2

如果您想要第三个经纪人:

If you want a third broker:

cp config/server.properties config/server3.properties

编辑config/server3.properties并替换现有的配置值，如下所示:

Edit config/server3.properties and replace the existing config values as follows:

broker.id=3
port=9094
log.dir=/tmp/kafka-logs-3

如果您在其他计算机上运行，​​则必须更改

if you run on different machines you must change

advertised.host.name=192.168.x.x

否则，例如，如果您在同一台vmware计算机中运行，则应仅如上所述更改端口和log.dir

else if you run in the same vmware machine, for example you should only change the port and log.dir as described above
