ZooKeeper集群部署实验 出现Error contacting service. It is probably not running.

原因: 三个节点, 仅启动了一个节点的zookeeper,最少启动两个节点的zookeeper。

前提:基础环境配置完成,ZooKeeper集群搭建完成

1.启动ZooKeeper服务

(切换到/root/zookeeper-3.4.14/bin目录下,  我的zookeeper-3.4.14上传到了/root/目录下)

切换目录

[root@z1 bin]# cd
[root@z1 ~]# cd /root/zookeeper-3.4.14/bin
[root@z1 bin]# 

在zookeeper-3.4.14/bin目录下, 启动ZooKeeper服务

[root@z1 bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /root/zookeeper-3.4.14/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

2.查看zookeeper状态, 出现Error contacting service. It is probably not running.

[root@z1 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /root/zookeeper-3.4.14/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

原因: 仅启动了此节点的zookeeper,最少启动两个节点的zookeeper

将另外一台或两台节点的ZooKeeper服务启动后:  状态为running,  Mode为 leader 或 follower

[root@z1 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /root/zookeeper-3.4.14/bin/../conf/zoo.cfg
Mode: leader

希望对大家有帮助!
