Kubeadm初始化报错：[ERROR CRI]: container runtime is not running: output:

在初始化kubeadm的时候出现了如下错误：

[root@centos7-1 ~]# sudo kubeadm init

[init] Using Kubernetes version: v1.26.0

[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`

按照如下命令进行操作

[root@centos7-1 ~]# rm -rf /etc/containerd/config.toml 
[root@centos7-1 ~]# systemctl restart containerd

然后再次执行初始化就可以了

[root@centos7-1 ~]# sudo kubeadm init

OK了！
