kubeadm初始化报错如下：

[root@ECS-k8s-master docker]# kubeadm init   --apiserver-advertise-address=192.168.2.2 --image-repository registry.aliyuncs.com/google_containers   --kubernetes-version v1.24.2   --service-cidr=10.140.0.0/16 --pod-network-cidr=10.240.0.0/16

网上查询光说让删除

rm /etc/containerd/config.toml

但其实，删除完后要重启 containerd 服务，不然不生效

完整如下：

rm /etc/containerd/config.toml
systemctl restart containerd

报错二

[wait-control-plane] Waiting for the kubelet to boot up the control plane as static Pods from directory "/etc/kubernetes/manifests". This can take up to 4m0s

kubeadm init \
--apiserver-advertise-address=10.1.1.1 \
--control-plane-endpoint=master \   这里用的是主机名，必须再 /etc/hosts 里有
--image-repository registry.cn-hangzhou.aliyuncs.com/lfy_k8s_images \
--kubernetes-version v1.21.0 \
--service-cidr=10.96.0.0/16 \
--pod-network-cidr=192.168.0.0/16

我上面遇到的报错就是 master 主机名不对导致连不上
