系统初始化
yum install -y vim
yum install -y git
yum install -y wget
setenforce 0
sed -i 's/enforcing/disabled/' /etc/selinux/config
安装docker
yum install -y docker
systemctl enable docker.service
systemctl start docker.service
配置yum源
cat > /etc/yum.repos.d/kubernetes.repo << EOF
[kubernetes]
name=Kubernetes

安装kubeadm、kubelet、kubectl
yum install -y kubelet-1.13.3
yum install -y kubeadm-1.13.3
yum install -y kubectl-1.13.3
systemctl enable kubelet.service
systemctl start kubelet.service
说明：
--apiserver-advertise-address=10.44.41.236 是master的ip地址，
--service-cidr=10.96.0.0/16 是service的地址段，可自定义
--pod-network-cidr=10.244.0.0/16 是pod的地址段，可自定义**
初始化完成之后，会有如下提示，按照提示操作即可
Your Kubernetes master has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
You can now join any number of machines by running the following on each node
as root:
kubeadm join 10.44.41.236:6443 --token 7dtiw9.7ytxxxxxx89x7tr --discovery-token-ca-cert-hash sha256:c2a0b41860xxxxxxff8dcb5d3b3a460
task 2 创建pod网络，先下载yml文件，再下载docker镜像，然后把docker镜像tag成与yml文件中一致，最后apply
wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
sudo docker pull akinlau/flannel-v0.11.0:v0.11.0
sudo docker images
sudo docker tag ff281650a721 quay.io/coreos/flannel:v0.11.0-amd64
kubectl apply -f kube-flannel.yml
task 3 执行完命令之后在master上查看节点状态，node节点需要很久才能达到ready状态，因为下载flannel镜像很慢，可以将master上的镜像docker save保存，然后拷贝到node上执行docker load导入
