由以下原因导致：java.lang.IllegalArgumentException：服务器缺少选举端口：1

问题描述

我是kafka的新手，我通过参考https://codeforgeek.com/how-to-setup-zookeeper-cluster-for-kafka/

开始进行Zookeeper集群设置。

这有三个Zookeeper实例，我可以启动第一个Zookeeper实例，但是在第二个节点中Zookeeper没有启动。

我使用此命令来启动Zookeeper-bin/zookeeper-server-start.sh config/zookeeper.properties

我还创建了myid文件，其中写有2号。

引发以下错误，

[root@kafka2 kafka_2.12-2.2.2]# bin/zookeeper-server-start.sh config/zookeeper.properties

解决方法

我终于找到答案了。实际上，我错过了server.1中config/zookeeper.properties的端口（2888）。

问题

server.1=<ip of first server>:3888
server.2=0.0.0.0:2888:3888
server.3=<ip of third server>:2888:3888

工作

server.1=<ip of first server>:2888:3888
server.2=0.0.0.0:2888:3888
server.3=<ip of third server>:2888:3888
