初始化kubeadm出错-端口被占用的错误
6.echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> /etc/profile解决8080端口被拒绝
The connection to the server localhost:8080 was refused - did you specify the right host or port?解决--对我的情况来说是有效的，我在用kubectl get nodes查看的时候报了这个错
echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> /etc/profile
7.主节点启动成功

Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:https://kubernetes.io/docs/concepts/cluster-administration/addons/Then you can join any number of worker nodes by running the following on each as root:kubeadm join 192.168.244.139:6443 --token ribaxq.5em1azk4rbyp556k \--discovery-token-ca-cert-hash sha256:b4ec8b44e81cc9c35d34c327095fb37c793537b25c396f492c83a8af46a5a22d
