#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

#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
