在尝试启动Kubernetes Kubelet服务时遇到错误，问题在于kubelet配置中的cgroupdriver设置。日志显示配置为'systemd'，但需要更改为'cgroupfs'。解决方法是编辑Docker的daemon.json文件，将cgroupdriver设置为'cgroupfs'，然后重新加载守护进程，启用并重启kubelet服务。

解决方案：

删除docker配置文件中的native.cgroupdriver=systemd或者将systemd改为cgroupfs

vim /etc/docker/daemon.json
{
"exec-opts": ["native.cgroupdriver=cgroupfs"]
}

systemctl daemon-reload
systemctl enable kubelet
systemctl restart kubelet
systemctl status kubelet
