回到老家后手边没有趁手的电脑，只有一个2003年左右的超低配置松下牌笔记本，安装了Ubuntu1604Server版虚拟环境后，在上面试着搭建Kubernetes的单机展示环境，以下是踩坑过程：

kubernetes master is running at http://192.168.207.131:8080

To further debug and diagnose cluster problems,use 'kubectl cluster-info dump'. root@googlebigtable-virtual-machine:/usr/local/kubernetes-1.4.12/cluster# 【注意：执行/usr/local/kubernetes-1.4.12/cluster/ubuntu/ download-release.sh成功并下载etcd、flannel、Kubernetes完毕后，将/usr/local/kubernetes-1.4.12/cluster/ubuntu/ download-release.sh清空，因为 /usr/local/kubernetes-1.4.12/cluster/kube-up.sh 会调用/usr/local/kubernetes-1.4.12/cluster/ubuntu/ download-release.sh并执行下载任务】【在浏览器中输入http://192.168.207.131:8080可发现Kubernetes集群已经启动成功】
