Session 0x0 for sever , Closing socket connection. Attempting reconnect except it is a SessionExpire

解决方案：换版本号，我测试的么问题的版本号3.4.12

背景：

使用dockerfile镜像搭建Kafka集群时，里面zookeeper集群连接测试时报了上述的错误，然后网上找了很长时间，通过
https://issues.apache.org/jira/browse/ZOOKEEPER-3828
这个issue找到了解决方案。

连接测试，一直报错

排错过程

一开始zk启动报错了，是以前遇到的一个错误。解决方法：https://blog.csdn.net/qq_42873554/article/details/105672258

Cannot open channel to 2 at election address Connection refused

先把–rm参数去掉，进入容器，ping看是否是网络问题。【容器里面没有ping需要先下载】

apt-get update
apt-get install ping

看zk的各个容器，选主从日志没有问题，正常启动。实在是摸不着头脑了，就像网友求助了。发现资料特被少，最后在zk apache网站的issue上找到了相同的问题。

下面的几种方案，大体都试了下，然后基本上就是改版本号比较靠谱。

正常的：3.4.12。我试过出现问题：3.6, 3.6.2
