kubeadm reset后安装遇到的错误:Unable to connect to the server: x509: certificate signed by unknown authority

前面通过kubeadm reset重置k8s环境之后，执行了kubeadm init命令

[root@m ~]# kubeadm init --kubernetes-version=1.14.0 --apiserver-advertise-address=192.168.56.51 --pod-network-cidr=10.244.0.0/16

初始化完成后按照出现的提示执行了如下命令:

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

执行完毕后，想通过kubectl cluster-info命令查看下集群环境，但是提示上述错误，使用其他kubectl命令也提示相关错误

尝试了很多办法都没有解决，然后想到我在执行上述mkdir的时候会咨询我是否覆盖，我是默认回车，改成输入y之后就可以了

（我想删除原来的文件夹也是可以的），应该是之前的系统配置文件影响到了这次初始化
