kubernetes工作节点处于“NotReady”状态

我正在尝试使用Kubernetes 1.13.1设置我的第一个集群。主机初始化没问题，但我的两个工作节点都是NotReady。 kubectl describe node显示Kubelet停止在两个工作节点上发布节点状态。在其中一个工作节点上，我得到日志输出

kubelet[3680]: E0107 20:37:21.196128 3680 kubelet.go:2266] node
"xyz" not found.
这是完整的细节：

我正在使用Centos 7和Kubernetes 1.13.1。

初始化完成如下：

[root@master ~]# kubeadm init --apiserver-advertise-address=10.142.0.4 --pod-network-cidr=10.142.0.0/24
成功初始化集群：

You can now join any number of machines by running the following on each node
as root:
kubeadm join 10.142.0.4:6443 --token y0epoc.zan7yp35sow5rorw --discovery-token-ca-cert-hash sha256:f02d43311c2696e1a73e157bda583247b9faac4ffb368f737ee9345412c9dea4
部署flannel CNI：

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

join命令运行正常。

[kubelet-start] Activating the kubelet service [tlsbootstrap] Waiting for the kubelet to perform the TLS Bootstrap... [patchnode] Uploading the CRI Socket information "/var/run/dockershim.sock" to the Node API object "node01" as an annotation

此节点已加入群集：

• Certificate signing request was sent to apiserver and a response was received.
• The Kubelet was informed of the new secure connection details.
  Run 'kubectl get nodes' on the master to see this node join the cluster.

kubectl获取节点的结果：

[root@master ~]# kubectl get nodes
