### 启动过程中的一些错误
#### hostname 配置问题
```sh
W0414 11:15:16.799163 11416 configset.go:202] WARNING: kubeadm cannot validate component configs for API groups [kubelet.config.k8s.io kubeproxy.config.k8s.io]nodeRegistration.name: Invalid value: "vm_74_51_centos": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')To see the stack trace of this error execute with --v=5 or higher

解决方法

[root@VM_74_51_centos /data/minikube]# hostnamectl set-hostname vm-74-51-centos

conntrack-tools 没有安装

* minikube v1.9.2 on Centos 7.2
* Using the none driver based on user configuration
X Sorry, Kubernetes v1.18.0 requires conntrack to be installed in root's path

解决方法

[root@VM_74_51_centos /data/minikube]# apt-get install conntrack

kubectl install

curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl

apt-get remove docker docker-engine docker.io containerd runc

apt-get update
 sudo apt-get install \
    apt-transport-https \
    ca-certificates \

    lsb-release

echo \
  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

 sudo apt-get update
 sudo apt-get install docker-ce docker-ce-cli containerd.io
