现象

服务器连不上，kafka报connection refused

测试发现kafka某台node(xx)的问题，登录上去也各种错误，zkServer.sh restart可以完成，但status报连不上。报错比较迷惑人，打开java log看到其他错误：

[myid:3] - INFO  [ListenerThread:QuorumCnxManager$Listener@534] - My election bind port: /yy:3888

java.net.BindException: Cannot assign requested address

...

[myid:3] - WARN  [WorkerSender[myid=3]:QuorumCnxManager@400] - Cannot open channel to 1 at election address /xx:3888

java.net.ConnectException: Connection refused

其实这个错误可以看出来，出现了xx和yy2个地址，说明它认错了自己

解决方案

从zoo.cfg看下datadir，将下面的myid改成和zoo.cfg里的自己一样的。比如xx是

server.1=xx:2888:3888
server.2=yy:2888:3888
server.3=zz:2888:3888

那么它的myid必须是1
