安装openvpn来获取docker镜像（不是本文重点不做详述）

软件包安装

1 关闭iptables,禁用firewalld,关闭selinux
2 配置yum仓库(使用阿里云的镜像仓库 )

要4个yum源 CentOS-Base.repo epel.repo docker-ce.repo kubernetes.repo

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg

3 安装kubelet kubeadm kubectl docker-ce 并且注册系统服务

yum install -y kubelet kubeadm kubectl docker-ce
systemctl enable kubelet && systemctl start kubelet
