本文详细记录了在使用Kubernetes1.14.0版本时遇到的启动错误，包括多个端口被占用及关键配置文件已存在的问题。文章提供了具体的错误信息，并指导如何通过删除特定配置文件来解决这些问题，确保Kubernetes集群能够正常启动。

[init] Using Kubernetes version: v1.14.0
[preflight] Running pre-flight checks
error execution phase preflight: [preflight] Some fatal errors occurred:
	[ERROR Port-6443]: Port 6443 is in use
	[ERROR Port-10251]: Port 10251 is in use
	[ERROR Port-10252]: Port 10252 is in use
	[ERROR FileAvailable--etc-kubernetes-manifests-kube-apiserver.yaml]: /etc/kubernetes/manifests/kube-apiserver.yaml already exists
	[ERROR FileAvailable--etc-kubernetes-manifests-kube-controller-manager.yaml]: /etc/kubernetes/manifests/kube-controller-manager.yaml already exists
	[ERROR FileAvailable--etc-kubernetes-manifests-kube-scheduler.yaml]: /etc/kubernetes/manifests/kube-scheduler.yaml already exists
	[ERROR FileAvailable--etc-kubernetes-manifests-etcd.yaml]: /etc/kubernetes/manifests/etcd.yaml already exists
	[ERROR Port-10250]: Port 10250 is in use

	[ERROR Port-2380]: Port 2380 is in use
	[ERROR DirAvailable--var-lib-etcd]: /var/lib/etcd is not empty
[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`

删除上面的配置文件，重启

rm -rf /etc/kubernetes/manifests/kube-apiserver.yaml /etc/kubernetes/manifests/kube-controller-manager.yaml /etc/kubernetes/manifests/kube-scheduler.yaml /etc/kubernetes/manifests/etcd.yaml
