好吧..世界上的每一项服务都可以连接到我的动物园管理员（除了 kafka）。下面是我在 server.properties 文件中的连接字符串

zk.connect=1.dzk.syd.druid.neo.com:2181, 2.dzk.syd.druid.neo.com:2181

在两个 Zookeeper 服务器上拥有所有端口 ....完全混杂模式。我什至可以从kafka服务器telnet到zookeeper服务器..

telnet  2.dzk.syd.druid.neo.com 2181
Trying 54.252.183.218...
Connected to 2.dzk.syd.druid.neo.com.
Escape character is '^]'.

所以....相当困惑为什么kafka不会连接到zookeeper？

我正在使用 ubuntu 12.04 和 kafka 0.7.2

在您的 kafka/config/server.properties 中，应该有一个属性

#host.name=localhost

如果您取消了注释，或者将其设置为另一个名称，那么该名称应该在 /etc/hosts 文件中

自从这个问题得到回答已经有一段时间了，但如果它可以帮助这里的人，我是如何解决它的：

实际上我正在使用 Ansible 剧本来安装 Kafka 集群，并且在 zookeeper.properties 文件中生成的参数没有正确排序：

server.1=0.0.0.0:2888:3888
server.2=kafka-4:2888:3888
server.3=kafka-5:2888:3888
server.4=kafka-3:2888:3888
server.5=kafka-2:2888:3888

把它们按正确的顺序排列，

server.1=0.0.0.0:2888:3888
server.2=kafka-2:2888:3888
server.3=kafka-3:2888:3888
server.4=kafka-4:2888:3888
server.5=kafka-5:2888:3888

然后重新启动Kafka服务，修复它。
