Posted 2021-06-03 闭关苦炼内功

出现问题：
启动ZK三节点集群，master节点查看状态报错，另外两个节点均正常

看截图

报错详情：

Client port found: 2181. Client address: localhost.
Error contacting service. It is probably not running.

---

根本原因：
master节点没关墙

---

终极解决方法：

• 解法1：通过命令进入cd /usr/local/zookeeper/data中找到zookeeper_server.pid文件，然后干掉它，重启zookeeper集群

• 解法2：关闭防火墙，systemctl stop firewalld.service，重启zookeeper。

一定要注意细节，搞之前就要关墙

做技术，一定要严谨！！！
