释放双眼，带上耳机，听听看~！
环境
两台虚拟机
一个脚本的安装包
步骤一
两台虚拟机都安装doker
systemctl stop firewalld.service && systemctl disable firewalld.service
setenforce 0
sed -i.bak ‘s/SELINUX=enforcing/SELINUX=permissive/’ /etc/selinux/config
创建一个 vi /etc/yum.repos.d/docker.repo 文件，内容如下：
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
安装新版本 Docker
yum install -y docker-engine
开启服务
systemctl start docker
设置两台虚拟机的hostname
master上执行：
[root@localhost ~]# hostnamectl –static set-hostname k8s-master
node1上执行
[root@localhost ~]# hostnamectl –static set-hostname k8s-node-1
修改两台虚拟机的/etc/hosts文件
vi /etc/hosts
192.168.0.220 k8s-master
192.168.0.221 k8s-node-1
下面进行分开设置
k8s-master 设置（虚拟机内存为2g）
