kubernetes初始化集群时报错

报错：kubernetes初始化端口占用及文件存在（本人是之前初始化过一次）

[root@master ~]# kubeadm init --apiserver-advertise-address=192.168.20.200 --image-repository=registry.aliyuncs.com/google_containers --kubernetes-version=v1.28.0 --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12 --cri-socket=unix:///var/run/cri-dockerd.sock
[init] Using Kubernetes version: v1.28.0
[preflight] Running pre-flight checks
error execution phase preflight: [preflight] Some fatal errors occurred:

[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`
To see the stack trace of this error execute with --v=5 or higher

解决方法：

首先先清空上次初始化的产生的文件

rm -rf /etc/kubernetes/*
rm -rf /var/lib/etcd/*
rm -rf ~/.kube/*

下载这个包来停用被占用的端口

yum install lsof -y

停用被占用的端口

lsof -i:15909|grep -v "PID"|awk '{print "kill -9",$2}'|sh

重启

kubeadm reset

然后再初始化

kubeadm init
