部署内容是一个主节点和2个从节点，博客园的编辑器没找到编辑目录结构的功能。
master centos
yum -y install epel-realse
yum update
hostnamectl --static set-hostname k8s-master
查看uname -a
查看本机ip

192.168.241.162 k8snode2' >> /etc/hosts
如果修改错误，还可以用命令vi /etc/hosts来继续修改，修改完成查看
systemctl disable firewalld.service
systemctl stop firewalld.service
firewall-cmd --state 查看防火墙状态
yum install etcd -y
编辑文件，修改带颜色部分信息
vi /etc/etcd/etcd.conf
启动并验证状态，
systemctl start etcd 启动服务
也可以这样验证服务是否启动
yum install docker
配置docker文件
设置开机启动 ，启动服务，查看服务状态
chkconfig docker on
service docker start
service docker status
docker修改国内镜像加速 vi /etc/docker/daemon.json
{

}
yum install kubernetes
配置并运行组件

systemctl start kube-controller-manager.service
systemctl enable kube-scheduler.service
systemctl start kube-scheduler.service
验证服务状态
service kube-controller-manager status
service kube-apiserver status
service kube-scheduler status
验证服务是否开机启动 enabled
systemctl list-unit-files |grep kube-controller-manager
systemctl list-unit-files |grep kube-apiserver
systemctl list-unit-files |grep kube-scheduler
yum install flannel
配置flannel
vi /etc/sysconfig/flanneld
配置key
etcdctl mk /atomic.io/network/config '{ "network": "192.168.0.0/16" }'
如果设置错误，重新修改，查看
设置开机启动flanneld ，并启动flanneld ，重启docker，重启master组件
systemctl enable flanneld.service
systemctl start flanneld.service 启动有点久
service docker restart
systemctl restart kube-apiserver.service
systemctl restart kube-controller-manager.service

查看是否成功
回到k8smaster
kubectl -s http://k8s-master:8080 get node
kubectl get nodes
如果没有找到资源，请对比节点配置文件修改成功。
安装覆盖网络验证是否成功
- 关闭iptables，防火墙
- 主机安装etcd,docker,flannel；节点机安装docker,flannel
yum install -y etcd docker flannel;yum install -y docker flannel
