same problem

reproduce

start zk

cd ~/software/apache-zookeeper-3.6.2-bin/bin
sh zkServer.sh start

run dubbo-admin

git clone [email protected]:apache/dubbo-admin.git
cd dubbo-admin
mvn clean package -Dmaven.test.skip=true
mvn --projects dubbo-admin-server spring-boot:run

很明显端口占用，所以我就把对应端口占用kill了重新启动

kill -9 `lsof -i:8080 | awk '{print $2}'`

然后再启动就会连接zk超时

org.apache.curator.CuratorConnectionLossException: KeeperErrorCode = ConnectionLoss

查看zk进程也发现消失了

这个主要是由于zk 3.5.0 引入了jetty，默认启动的端口是8080，上面kill的相当于是zk进程 zk version changelog

所以把默认zk admin的端口变一下或者改一下dubbo-admin的端口就可以了
