1 kubernetes镜像切换成国内源
访问 阿里云镜像：
M1M2芯片的arm64架构需要更改：
cat > /etc/yum.repos.d/kubernetes.repo << EOF [kubernetes] name=Kubernetes baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64 enabled=1 gpgcheck=0 repo_gpgcheck=0 gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg EOF
2 安装 kubelet/kubeadm/kubectl
注意指定版本！否则直接给你安装了最新版。
yum install -y kubelet-1.27.0 kubeadm-1.27.0 kubectl-1.27.0
3 启动 kebelet
3.1 自启动
kebelet是任务执行者，需要配置成开机自启动
[root@icv-k8s-node-1 ~]# systemctl enable kubelet Created symlink from /etc/systemd/system/multi-user.target.wants/kubelet.service to /usr/lib/systemd/system/kubelet.service. [root@icv-k8s-node-1 ~]# systemctl start kubelet [root@icv-k8s-node-1 ~]# systemctl status kubelet
3.2 启动kubelet失败
查看kebelet状态：
[root@icv-k8s-node-1 ~]# systemctl status kubelet ● kubelet.service - kubelet: The Kubernetes Node Agent Loaded: loaded (/usr/lib/systemd/system/kubelet.service; enabled; vendor preset: disabled) Drop-In: /usr/lib/systemd/system/kubelet.service.d └─10-kubeadm.conf Active: activating (auto-restart) (Result: exit-code) since Thu 2023-06-29 15:34:30 CST; 9s ago Docs: https://kubernetes.io/docs/ Process: 13284 ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_CONFIG_ARGS $KUBELET_KUBEADM_ARGS $KUBELET_EXTRA_ARGS (code=exited, status=1/FAILURE) Main PID: 13284 (code=exited, status=1/FAILURE) Jun 29 15:34:30 icv-k8s-node-1 systemd[1]: Unit kubelet.service entered failed....

因为 k8s 还没配置完全呢。
禁用containerd
vim /etc/containerd/config.toml
重启：
[root@icv-k8s-node-2 ~]# systemctl restart containerd [root@icv-k8s-node-2 ~]# systemctl restart kubelet [root@icv-k8s-node-2 ~]# systemctl status kubelet ● kubelet.service - kubelet: The Kubernetes Node Agent Loaded: loaded (/usr/lib/systemd/system/kubelet.service; enabled; vendor preset: disabled) Drop-In: /usr/lib/systemd/system/kubelet.service.d └─10-kubeadm.conf Active: activating (auto-restart) (Result: exit-code) since Thu 2023-06-29 15:45:43 CST; 6s ago Docs: https://kubernetes.io/docs/ Process: 15792 ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_CONFIG_ARGS $KUBELET_KUBEADM_ARGS $KUBELET_EXTRA_ARGS (code=exited, status=1/FAILURE) Main PID: 15792 (code=exited, status=1/FAILURE) Jun 29 15:45:43 icv-k8s-node-2 systemd[1]: Unit kubelet.service entered failed state. Jun 29 15:45:43 icv-k8s-node-2 systemd[1]: kubelet.service failed. [root@icv-k8s-node-2 ~]#
此时还是报错的，但错误日志少了最后一行，哈哈哈！如何修正，请看系列的下一篇文章！
