阿里云zk集群搭建遇到的坑

2022-01-22 15:21:32,482 [myid:2] - WARN  [WorkerSender[myid=2]:QuorumCnxManager@685] - Cannot open channel to 4 at election address hadoop1004/106.15.3.163:3888
java.net.ConnectException: Connection refused (Connection refused)

如果碰到这样的错误，zk能够启动，jps也有，就是status显示不了，就去阿里云配置一下安全组添加端口2181,2888,3888
