系统环境:CentOS Linux release 7.3.1611 (Core)

1、关闭selinux，关闭firewalld，关闭swap

systemctl stop firewalld && systemctl disable firewalld

swapoff -a

2、配置主机映射和修改主机名

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 (这几个软件需要去google的yum源下载，建议下本地vpnFQ，把软件包下载下来)

5、systemctl start kubelet && systemctl enable kubelet

6、master端导入需要镜像（详细见软件包）

7、kubeadm进行初始化：

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 #该参数指定自己内网地址和映射

在执行过程中，要等几分钟,然后执行以下命令：

然后执行如下命令：

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进行查看：

kubectl get cs

kubectl get nodes

8、注意：

记住该条命令：kubeadm join –token d506ef.63c05fa829529565 10.2.0.37:6443 –discovery-token-ca-cert-hash sha256:4cd1954bf2a1c0904f92328d33bc25471604abd918e019b3c1905289fb8130f2 #在node节点执行该条命令，–token是有有效期的，默认是24小时

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 #执行会输出一下内容：

10、kubectl get pod -n kube-system #注意红框内出现Running状态然后在node节点

=========================================================================================

在node节点部署

1、同master节点前五步一样部署

2、导入镜像：其实我导入多了，只需要导入一下几个就可以了:gcr.io/google_containers/kube-apiserver-amd64、gcr.io/google_containers/etcd-amd64、quay.io/coreos/flannel、gcr.io/google_containers/etcd-amd64

3、执行master的第8步，就可以了，然后在master上执行：kubectl get nodes,看到如下图：

注意：要想在node节点执行该条命令，需要再node上执行以下命令：

sudo cp /etc/kubernetes/admin.conf $HOME/

sudo chown $(id -u):$(id -g) $HOME/admin.conf

export KUBECONFIG=$HOME/admin.conf
不然会出现以下错误:The connection to the server localhost:8080 was refused - did you specify the right host or port?(单独开终端也会出现）
