Ruoyi微服务部署问题记录,Client not connected, current status:STARTING_error c.a.c.n.r.nacosserviceregistry - [register,8

错误复现

在往服务器上部署RuoYi微服务的时候，发生了一个错误。Client not connected, current status:STARTING。
我在服务器上部署了一个alibaba的nacos-2.2.0配置中心、注册中心。然后在本地运行Ruoyi微服务的时候，使用了服务器上的nacos地址。121.36.97.XXX:8848。然后就报以下错误。

错误原因

版本问题

网上说是因为版本的问题，为此我特意安装了nacos-2.2.0版本，但是还是会报错。官网版本说明

nacos-2.0.0版本压测

然后我查看了一下我服务器上的端口号。

sudo ufw status verbose
1

注意：此处我已经新增了9848,9849两个端口号。

服务器安全组中打开9848,9849两个端口号。

可能是服务器安装nacos出错

以上问题都配置问。就可以正常启动了。

下面这个是我的个人公共号 只会写Bug的程序猿，大家可以关注一下。相互交流学习。
