案例环境：
server端二进制文件
https://dl.k8s.io/v1.8.13/kubernetes-server-linux-amd64.tar.gz
node端二进制文件
https://dl.k8s.io/v1.8.13/kubernetes-node-linux-amd64.tar.gz
全部修改主机名配置host解析
在192.168.100.101上的配置
master服务器安装etcd
配置etcd,并启动服务器配置开机自启动（注意URLS）
yum install etcd -y
tar -zxf kubernetes-server-linux-amd64.tar.gz
mkdir -p /opt/kubernetes/{bin,cfg}
mv kubernetes/server/bin/{kube-apiserver,kube-scheduler,kube-controller-manager,kubectl} /opt/kubernetes/bin

至此master就已经配置完成，如若配置中有错误，可以通过#journalctl -u 服务名称查看报错
配置环境变量
echo "export PATH=\$PATH:/opt/kubernetes/bin" >> /etc/profile
source /etc/profile
在192.168.100.102上的配置
安装配置docker（安装docker之前将yum源中的gpgcheck改为0）
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum makecache fast

其他节点加入集群与node01方式相同，但需修改kubelet的--address和--hostname-override选项为本机IP即可。
在master查看node命令
