报错： 这个错误信息表明你的容器运行时（container runtime）没有正常运行，具体是因为CRI（容器运行时接口）v1版本的API没有为特定的端点实现。这通常发生在使用containerd作为容器运行时时。错误信息中提到的端点是
[ERROR CRI]: container runtime is not running: output: time="2023-12-01T23:30:36+08:00" level=fatal msg="validate service connection: CRI v1 runtime API is not implemented for endpoint \"unix:///run/containerd/containerd.sock\": rpc error: code = Unimplemented desc = unknown service runtime.v1.RuntimeService"
解决：我是这么解决的
1.检查containerd服务状态：首先确保containerd服务已经启动并且运行中。你可以使用以下命令来检查服务状态：udo systemctl status containerd 没启动的话启动
2.检查配置文件：确认containerd的配置文件（通常位于/etc/containerd/config.toml）是否正确配置了CRI插件。如果没有，你可能需要启用CRI插件并指定正确的API版本。
我修改了配置文件就好了 vim /etc/containerd/config.toml

重启containerd服务：在更改任何配置或更新软件包后，你需要重启containerd服务：
查看日志：查看containerd的日志可能会提供更多的信息，以帮助诊断问题。使用以下命令查看日志：journalctl -u containerd
在执行 kubeadm init --config=kubeadm.yaml --ignore-preflight-errors=SystemVerification 就好了
kubeadm init --config=kubeadm.yaml --ignore-preflight-errors=SystemVerification
别的解决方法有：卸载重新安装
#kubelet 配置文件 /usr/lib/systemd/system/kubelet.service #重载配置 systemctl daemon-reload #重新安装 kubeadm reset 卸载重新安装 yum remove -y kubelet-1.26.0 kubeadm-1.26.0 kubectl-1.26.0 yum install -y kubelet-1.26.0 kubeadm-1.26.0 kubectl-1.26.0 systemctl enable kubelet systemctl restart containerd kubeadm config print init-defaults > kubeadm.yaml kubeadm init --config=kubeadm.yaml --ignore-preflight-errors=SystemVerification
