卡夫卡因Zookeeper超时而关机

Question

我正在尝试在单个Zookeeper节点中与3个Kafka经纪人一起安装Kafka设置，但是我看到Kafka进程在几分钟之内崩溃并在Kafka日志中引发错误：

Answer 1

您是否在该端口上启动了Zookeeper？似乎Kafka服务器无法连接到zookeeper。 如果您使用的是Linux，则可以使用netstat -anlp | grep 2181

检查端口的网络状态

Answer 2

[Windows指令]

转到

C：\ Windows \ System32 \ drivers \ etc

并添加以下行：

0.0.0.0        localhost
192.168.1.103  localhost

并保存文件
