系統環境:CentOS Linux release 7.3.1611 (Core)
鏡像下載地址:
備注:鏡像資源比較大:分成三份:（需要VPN也可以找我）

1、關閉selinux，關閉firewalld，關閉swap
systemctl stop firewalld && systemctl disable firewalld
swapoff -a
2、配置主機映射和修改主機名
hostnamectl set-hostname k8s-master
3、yum -y install docker && systemctl start docker && systemctl enable docker
4、 yum -y install kubectl kubelet kubernetes-cni kubeadm (這幾個軟件需要去google的yum源下載，建議下本地vpn翻牆，把軟件包下載下來)
5、systemctl start kubelet && systemctl enable kubelet
6、master端導入需要鏡像（詳細見軟件包）
7、kubeadm進行初始化：
kubeadm init --kubernetes-version=v1.9.1 --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=0.0.0.0 --apiserver-cert-extra-sans=10.2.0.35,127.0.0.1,k8s-master
--apiserver-cert-extra-sans #該參數指定自己內網地址和映射
在執行過程中，要等幾分鍾,然后執行以下命令：
然后執行如下命令：
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
成功以后可以指定一下命令進行查看：
kubectl get cs
kubectl get nodes
8、注意：
記住該條命令：kubeadm join --token d506ef.63c05fa829529565 10.2.0.37:6443 --discovery-token-ca-cert-hash sha256:4cd1954bf2a1c0904f92328d33bc25471604abd918e019b3c1905289fb8130f2 #在node節點執行該條命令，--token是有有效期的，默認是24小時
9、部署 flannel
mkdir -p ~/k8s/
wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
kubectl apply -f kube-flannel.yml #執行會輸出一下內容：
10、kubectl get pod -n kube-system #注意紅框內出現Running狀態然后在node節點
=========================================================================================
在node節點部署
1、同master節點前五步一樣部署
2、導入鏡像：其實我導入多了，只需要導入一下幾個就可以了:gcr.io/google_containers/kube-apiserver-amd64、gcr.io/google_containers/etcd-amd64、quay.io/coreos/flannel、gcr.io/google_containers/etcd-amd64
3、執行master的第8步，就可以了，然后在master上執行：kubectl get nodes,看到如下圖：
注意：要想在node節點執行該條命令，需要再node上執行以下命令：
sudo cp /etc/kubernetes/admin.conf $HOME/
sudo chown $(id -u):$(id -g) $HOME/admin.conf
export KUBECONFIG=$HOME/admin.conf
不然會出現以下錯誤:The connection to the server localhost:8080 was refused - did you specify the right host or port?(單獨開終端也會出現）
