记dubbo无法注册的问题

今天启动服务端的时候报错：

Failed to register consumer://192.168.60.1/com.duck.service.UserService?application=user-web&category=consumers&check=false&default.check=false&default.reference.filter=regerConsumerFilter&default.timeout=600000&dubbo=2.6.0&interface=com.atguigu.gmall.service.UserService&methods=getReceiveAddressByMemberId,getAllUser&pid=12648&side=consumer&timestamp=1583642177210 to zookeeper zookeeper://47.112.171.153:2181/com.alibaba.dubbo.registry.RegistryService?application=user-web&client=zkclient&dubbo=2.6.0&interface=com.alibaba.dubbo.registry.RegistryService&pid=12648&timestamp=1583642177225, cause: Zookeeper is not connected yet!

问题原因，这是由于linux开启了防火墙，导致注册失败。

解决：关闭linux（基于CentOS7）防火墙

systemctl stop firewalld.service
