初始化kubernetes端口占用问题

执行 命令：
[root@oldxin-master17 ~]# kubeadm init --apiserver-advertise-address=192.168.1.17 --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.20.5 --service-cidr=10.96.0.0/12 --pod-network-cidr=10.244.0.0/16

发生报错信息：

原报错：

[WARNING IsDockerSystemdCheck]: detected "cgroupfs" as the Docker cgroup driver. The recommended driver is "systemd". Please follow the guide at https://kubernetes.io/docs/setup/cri/
error execution phase preflight: [preflight] Some fatal errors occurred:
	[ERROR Port-6443]: Port 6443 is in use
	[ERROR Port-10259]: Port 10259 is in use
	[ERROR Port-10257]: Port 10257 is in use

初步判定为端口占用，杀死进程

解决方案：

尝试杀死进程都没有用，最终重启一下kubeadm就可以了，如下：

[root@k8s-master01 ~]# kubeadm reset
