前言

在学习dubbo的时候需要监控消费者和生产者，所以需要安装dubbo-admin：
小编是在github上下载最新的Dubbo Admin 0.3.0，遇到了问题，这里记录一下

---

一、下载安装dubbo-admin

网上有很多大佬的教程，这里不再赘述，小编看的教程是

二、遇到问题

三、解决办法

如果有小伙伴不小看啰嗦的分析，直接看解决办法，如果想看小编的心路历程，请继续看分析思路

四、思路分析

这个dubbo-admin是一个标准的spring-boot项目，直接开启调试

1、从报错信息看（从上往下）

根据Caused by: java.lang.IllegalStateException: zookeeper not connected at org.apache.dubbo.remoting.zookeeper.curator.CuratorZookeeperClient.(CuratorZookeeperClient.java:87)

2、解决

现在只需要在前面传入的参数设置大一点超时时间，不用默认的超时时间就行，具体设置，见上解决办法

3、分析为什么会超时默认时间

小编用的zookeeper是在，远程的linux服务器上的（腾讯云），因为是学习用的，配置和延时都比较高，所以需要设置大一点

总结

这可能是最笨的办法，但是小编学习springboot+dubbo的开篇问题解决，希望大佬能指导更好的办法！学无止境，小伙伴们一起来挖坑吧！
