centos8启动zk集群失败：zk Error contacting service. It is probably not running.

【README】在 192.168.163.201 机器上启动zk ，并查看zk 这台；即集群只有2台机器， 201 202

【1】报错现场

在201上启动zk，如下：

[root@localhost zookeeper-3.4.10]# ./bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/module/zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost zookeeper-3.4.10]#
[root@localhost zookeeper-3.4.10]#
[root@localhost zookeeper-3.4.10]# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/module/zookeeper-3.4.10/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

【2】解决方法

第一步：查看 zookeeper.out 输出日志，如下：

Cannot open channel to 2 at election address /192.168.163.202:3888

第2步：很明显，意识到 202 这台机器的 zk没有启动，

启动 202，如下：

经过查看 status， 202 是leader

第3步，我们查看201 的zk 状态（这里无需再次启动，因为201已经启动了），201是个 follower

bingo

小结：解决该问题的方法是在查看zk启动的日志文件， zookeeper.out 文件；
