    yum clean all
    yum makecache

#安装docker-ce 此步骤要是master和node都执行
    yum -y install yum-utils lvm2 device-mapper-persistent-data docker-ce

#启动docker
    systemctl enable docker
    systemctl start docker
    systemctl status docker

#daemon
    cp daemon.json /etc/docker/daemon.json

#重新启动
    systemctl restart docker
    systemctl status docker

# 基本组件

#安装kubeadm kubectl kubelet 
    yum install  kubelet kubeadm kubectl --disableexcludes=kubernetes

#启动kubelet
    systemctl enable kubelet
    systemctl start kubelet
    systemctl status kubelet

#初始化master 此步骤要是master执行
    
    kubeadm init --kubernetes-version=$K8S_VERSION  --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=$masteripaddr

#配置kube
    mkdir -p $HOME/.kube
    cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
    chown $(id -u):$(id -g) $HOME/.kube/config

#查看节点状态
    kubectl get nodes

#node
    kubeadm join $masteripaddr:6443 --token $token --discovery-token-ca-cert-hash $sha256

#安装网络插件
    kubectl apply -f kube-flannel.yml

#查看网络插件
    kubectl get pods --namespace kube-system

#安装dashboard
    kubectl apply -f kubernetes-dashboard.yaml
    kubectl get pods --namespace kube-system
    kubectl get svc --namespace kube-system

#获取token
    kubectl -n 命名空间名称（默认是kubs-system） describe secret $(kubectl -n kube-system get secret | grep 指定用户的名字（admin） | awk '{print $1}')

最后IP加端口登录dashboard，利用token登录
