The connection to the server localhost:8080 was refused - did you specify the right host or port?
解决方法：
mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config2 初始化 healthz
The HTTP call equal to 'curl -sSL http://localhost:10248/healthz' failed with error: Get "http://localhost:10248/healthz": dial tcp [::1]:10248: connect: connection refused
解决方法
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://q5vcymug.mirror.aliyuncs.com"],
"exec-opts": ["native.cgroupdriver=systemd"]
}
systemctl restart docker kubeadm reset -f3 检查不健康 healthz
kubectl get cs
报错：
Get "http://127.0.0.1:10251/healthz": dial tcp 127.0.0.1:10251: connect: connection
解决方法：
vim /etc/kubernetes/manifests/kube-controller-manager.yaml
注释掉27行：# - --port=0
vim /etc/kubernetes/manifests/kube-scheduler.yaml
注释掉19行：# - --port=0
然后master节点重启：kubelet（等待几秒即可）
systemctl restart kubelet.service
