    本文的大概内容：

    一、业务场景

    之前配置好的zookeeper突然就连接不上了，在这之前我重置了服务器密码，服务器重启过一次，然后就发现连接不上了。参考之前的解决方案，成功解决问题。

    跟我之前碰到过的一个docker配置对外端口的业务场景有点相像（事情是这样的，我们公司有三台服务器给我来运维，我在这三台服务器上面都配置过docker对外暴露的端口，但是后面运行了二三周的样子，服务器一台先后都出现了通过密钥文件无法登陆的情况，这三台服务器都是在腾讯云的，当时为了项目进度，就在腾讯云控制台重置了密码，咨询了腾讯云的客服人员，也没有给出明确的解决方案，对于docker对外暴露端口，给出了查看端口防火墙的意见，对于服务器为什么运行一段时间突然登陆不上，需要重置密码的情况未做出解答。后面我通过重新开放防火墙端口，解决了之前可以连接上docker对外暴露端口，后面重置密码却又不行的场景。）

    二、错误日志

    通过查看日志发现好像也端口连接不上，我看了看端口的情况，发现连接是tc6不上tcp，虽然很奇怪，但是也没深入了解。

    在这里插入图片描述

    三、解决方案

    在这里插入图片描述
    通过重新开放端口，就重新连接上了

    firewall-cmd --add-port=2181/tcp --permanent
firewall-cmd --reload
firewall-cmd --query-port=2181/tcp
systemctl restart docker
