问题描述一：

Cannot open channel to 2 at election address /192.168.60.132:3888

解决方案：
查看zookeeper配置文件zoo.cfg / zoo_sample.cfg中集群配置部分

server.1=zoo1-net1:2888:3888|zoo1-net2:2889:3889
server.2=zoo2-net1:2888:3888|zoo2-net2:2889:3889
server.3=zoo3-net1:2888:3888|zoo3-net2:2889:3889

这里server.1后面的 = 前后注意不要有空格

问题描述二：

 Unable to read additional data from server sessionid 0x0, likely server has closed socket

这里是网路通信问题
解决方案：

关闭各个节点主机之间的防火墙，如果单主机多节点构成的集群请省略，请另谋高就

查看防火墙状态
systemctl status firewalld停止防火墙
systemctl stop firewalld永久关闭防火墙
systemctl disable firewalld
