Socket error: bind: Address not available

[congmingdexiong]

请教各位，老师演示用虚拟机，ip就是固定一个，现在我使用阿里云服务器分公网和私网ip, 下面etcd配置， --listen-client-urls=http://172.26.178.195:2379, 必须写的是我私网IP，不然起不来；但是这样写的话，node节点kube-calico连过来会有错误 Dec 17 11:58:56 a docker[27052]: bird: Mesh_172_26_178_195: Socket error: bind: Address not available，求教大家怎么解！
