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
