报错查询  
error execution phase preflight: \[preflight\] Some fatal errors occurred  
\[ERROR FileAvailable--etc-kubernetes-kubelet.conf\]: /etc/kubernetes/kubelet.conf already exists

报错日志：

[preflight] Running pre-flight checks
    error execution phase preflight: [preflight] Some fatal errors occurred:
        [ERROR FileAvailable--etc-kubernetes-kubelet.conf]: /etc/kubernetes/kubelet.conf already exists
        [ERROR FileAvailable--etc-kubernetes-pki-ca.crt]: /etc/kubernetes/pki/ca.crt already exists
    [preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`

原因是：一些配置文件与服务已经存在  
解决方案：

#重置kubeadm 
    kubeadm reset

在运行kubeadm join命令

或者

原因：有残留文件  
解决方案：(有效)

#删除k8s配置文件和证书文件
    rm -rf /etc/kubernetes/kubelet.conf /etc/kubernetes/pki/ca.crt #删除k8s配置文件和证书文件
    # 
    kubeadm join 192.168.191.133:6443 --token xvnp3x.pl6i8ikcdoixkaf0 \
        --discovery-token-ca-cert-hash sha256:9f90161043001c0c75fac7d61590734f844ee507526e948f3647d7b9cfc1362d
