kafka 集群consumer 收不到消息

搭建了 3个zookeeper 伪分布式集群，kafka 也是三个broker,现在查看 _consumer_offset 是这样的，消费者收不到消息：

看这个是正常的，您可以先通过命令同时生产和消费，确认是否正常消费。

另外，如果还不行，得详细描述下你的操作步骤，不然我没办法帮你分析。

但是我明明搭建的是3个kafka的集群，但isr副本为什么只有一个，replica也是一个，不是会有另外两个kafka吗
现在我看只是broker=0的kafka服务起作用
另外我关掉一台kafak服务后，kafka消费端一直报服务不能用

另外我开起了kafka的SASL/PLIAN鉴权，单机可以正常消费
集群就是收不到消息，查看了consumer_offset.
希望您能给看看，是什么原因

半兽人 -> 芣杺～汸蔠 5年前

1、3个kafka集群，但你需要在创建主题的时候，指定副本的数量，默认是1个。（你可以通过上面命令大全增加副本数）
2、__consumer_offsets 这个主题一定要扩展，这个是存储offset的，不扩展，0宕机消费者就全不能用了。

但现在是消费者收不到消息，跟这个有关吗？

没有，副本数是耐用性的保障，如果你3个集群都正常，是没有问题的。

那可能是哪儿出现问题了呢？单个就可以收到消息的

朋友，你这个问题描述太少了，我都不知道你的具体操作步骤，我没办法帮你分析额。

换个方式问吧！如果我想搭建kafka集群，相应的搭建 zookeeper 集群来管理这个kafka 集群，则在配置过程中哪一项参数，保证了副本的耐用性，并且保证kafka集群的正常通信

zk集群5个节点，kafka集群3个以上。
topic分区的副本数 = 耐用性。
