Your Kubernetes master has initialized successfully!
To start using your cluster, you need to run (as a regular user):
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
You can now join any number of machines by running the following on each node
as root:
kubeadm join --token xxxxxxx 192.168.80.28:6443
7.创建kube的目录，添加kubectl配置(master节点)
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
8.用 kubectl 添加网络组件Calico(master节点)
kubectl apply -f
注意：此处坑为该文件未必下载的到，建议还是提前下载到本地，然后执行 kubectl apply -f <本地路径>
9.确认安装是否成功(master节点)
9.1 打开你的/var/log/messages，查看是否有报错，理论上，执行完上一步过去5分钟，日志应该不会有任何错误出现，如果持续报错，并且过了10分钟错误依然没有消失，检查之前的步骤是否有问题
9.2 运行 kubectl get pods --all-namespaces 查看结果,如果STATUS都为Running，恭喜你，你的master已经安装成功了。
注意：你的结果显示的条数未必和我完全一样，因为我这里有node节点的相关信息，而你还没有添加node节点。
[root@centos7-base-ok]# kubectl get pods --all-namespaces

10.安装node节点,执行在master节点执行成功输出的日志语句(node节点执行)
