在春季启动时使用Dubbo遇到“注册时没有提供商”

Question

This problem arises when consumers want to get the zookeeper value of the local Linux virtual machine

I used Springboot 2.1，Zookeeper is on the local Linux virtual machine. I've seen a very close answer, but I don't know how to set it up. The address is https://blog.csdn.net/chenxiaochan/article/details/78776304 . What he means is that the IP of the server published by the Dubbo service uses DHCP, not static. And through his method, I queried my own ip, which is really different from the IP registered in the registry. I've also tried to disable virtual network cards, but It means I can't connect to the local Linux virtual machine.

My provider application.properties

dubbo.application.name=provider-ticket
dubbo.registry.address=zookeeper://192.168.248.132:2181
dubbo.scan.base-packages=com.cq.providerticket.service

My consumer application.properties

dubbo.application.name=consumer-user
dubbo.registry.address=zookeeper://192.168.248.132:2181
dubbo.consumer.check=false
dubbo.registry.check=false
server.port=8081
dubbo.protocol.host=192.168.248.132
dubbo.provider.host=192.168.248.132

linux dokcer command

docker run --name zk01 -p 2181:2181 -p 20880:20880 --restart always -d zookeeperID

This is the Exception it reported.

Answer 1

If you use docker in linux virtual machine, linux system is run in virutal box or VMware Workstation

1. ssh to linux
2. vim /etc/sysconfig/network-scripts/ifcfg-eth0 or ifcfg-eth33 file
3. change the BOOTPROTO=dhcp to BOOTPROTO=static and set IPADDR=192.168.248.132
4. make sure 20880 and 2181 port is open through firewall

If you use docker for windows,linux virtual is in hyper-v, 192.168.248.132 is your windows computer ip

1. set the dubbo.registry.address=zookeeper://localhost:2181
2. set the dubbo.protocol.host=localhost and dubbo.provider.host=localhost
