Question

这是我在本地的设置：3个虚拟机（使用Virtualbox），kafka和zookeeper安装在这三个上。他们都在互相交谈。

我正在尝试使用本地的kafka-console-producer，这需要broker-list。我正在提供我的虚拟机的IP，但它似乎并没有起作用。我也在虚拟机上尝试过advertised.host属性，但对我没有任何影响。这是我的三台机器的server.properties：

服务器1：

broker.id=4
port=9092
host.name=10.30.3.4
advertised.host.name=10.30.3.4
advertised.port=9092
zookeeper.connect=10.30.3.4:2181
zookeeper.connection.timeout.ms=6000

服务器2：

broker.id=3
port=9092
host.name=10.30.3.3
advertised.host.name=10.30.3.3
advertised.port=9092
zookeeper.connect=10.30.3.3:2181
zookeeper.connection.timeout.ms=6000

服务器3：

broker.id=2
port=9092
host.name=10.30.3.2
advertised.host.name=10.30.3.2
advertised.port=9092
zookeeper.connect=10.30.3.2:2181
zookeeper.connection.timeout.ms=6000

我的虚拟机也有端口转发设置：类似地，对于其他两台机器，端口仅稍微调整一下。

我能够很好地连接到zookeeper，所以：

bin/zkCli.sh -server 127.0.0.1:9999

能够在VM上连接到zookeeper。但是，如果我尝试连接kafka-console-producer，当我尝试发送消息时它会失败：

bin/kafka-console-producer.sh --broker-list 127.0.0.1:9502 --topic partition2replica2 --timeout 3000

不确定我在这里做错了什么？有任何想法吗？（如果有人想要，我可以提供ifconfig输出）。任何帮助将不胜感激。

[编辑1]：添加zookeeper仲裁的输出：

据我了解您的设置，每个节点上的动物园管理员也应该在Quorum中相互支持3个kafka服务器实例作为一个群集。你只提供了kafka配置，所以我无法确定它们是否以这种方式配置。

您可以在每个zookeeper节点上使用4个字母命令进行检查，如下所示

echo stat | nc <zk ip> <zk port>
echo mntr | nc <zk ip> <zk port>

一个人应该是领导者＆＃34;其他两个应该是＆＃34;粉丝＆＃34;。

我不确定如果他们没有配置为法定人数，他们是否会按预期工作。

如何在Virtualbox上连接到kafka群集？
