我尝试执行

kubeadm init --apiserver-advertise-address 49.232.211.230 --pod-network-cidr=10.244.0.0/16 -v=9

打印日志:

最后:

    Unfortunately, an error has occurred:
        timed out waiting for the condition

    This error is likely caused by:
        - The kubelet is not running
        - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

    If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
        - 'systemctl status kubelet'
        - 'journalctl -xeu kubelet'

    Additionally, a control plane component may have crashed or exited when started by the container runtime.
    To troubleshoot, list all containers using your preferred container runtimes CLI.

    Here is one example how you may list all Kubernetes containers running in docker:
        - 'docker ps -a | grep kube | grep -v pause'
        Once you have found the failing container, you can inspect its logs with:
        - 'docker logs CONTAINERID'

我什至重装了系统，但还是这样。
我尝试了 kubernetes 文档中的所有 kubeadm 方法。
一直都是这样，没办法。
谢谢，请帮助我。

Answer 1

正如 kubeadm init 命令日志中提到的，这是 kubelet 服务器问题或 CRI 问题，请使用 kubeadm reset -f 命令休息您的集群并尝试按顺序执行以下步骤:

停止 Kubelet 和 CRI 服务:

sudo systemctl stop kubelet
sudo systemctl stop docker (if you are using docker)

刷新 iptables 并关闭 swapoff(重要的是，如果有任何防火墙服务正在运行，请确认 kubernetes_cluster_ports 已启用):

sudo iptables -F && sudo iptables -t nat -F && sudo iptables -t mangle -F && sudo iptables -X
sudo swapoff -a

启动 CRI 和 kubelet 服务并验证它工作正常(处于激活状态):

    sudo systemctl start --now docker
    sudo systemctl start --now kubelet
    sudo systemctl status kubelet 

初始化你的集群

    sudo kubeadm init

如果所有这些步骤都完成了，但您仍然遇到问题，请验证您的网络配置，因为网络问题，docker 无法为控制平面初始化特定的 pod。
