基础环境：
Virtual box
OS: Ubuntu:16.04
enp0s3:(Hostonly)192.168.56.102(提供pc端访问服务器-hostonly)
enp0s8:(NAT)10.0.3.15(访问外网，因为nat映射端原因，本地pc无法访问)
minikube使用的all-in-one方式，所以就放在了一台vm上，配置最好大一点，不然会卡！

离线安装包和镜像
链接:https://pan.baidu.com/s/10oqK80w5SJD2npOYpLZEkg 密码:u95p
1、安装docker-ce环境（引用官网）
https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-docker-ce-1
sudo apt-get update
Install packages to allow apt to use arepository over HTTPS:
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl\
software-properties-common
Add Docker's official GPG key:
curl -fsSLhttps://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
Verify that you now have the key with thefingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching forthe last 8 characters of the fingerprint.
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
Install Docker CE,Update the apt package index.
sudo apt-get update
Install the latest version of Docker CE, or goto the next step to install a specific version:
sudo apt-get install docker-ce
sudo systemctl enable docker
sudo systemctl start docker
2、需要下载minikube、kubectl(参考官网github)
https://github.com/kubernetes/minikube
下载命令：（由于防火墙端缘故，无法下载，在国外服务器拉取下来，本地离线安装）
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64&& chmod +x minikube
curl -Lo kubectlhttps://storage.googleapis.com/kubernetes-release/release/$(curl -shttps://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl&& chmod +x kubectl
离线安装操作：
cd /root
chmod +x minikube
mv minikube /usr/local/bin/
ln -sf /usr/local/bin/minikube/usr/bin/minikube
cd /root
chmod +x kubectl
mv kubectl /usr/local/bin
ln -sf /usr/local/bin/kubectl /usr/bin/kubectl
3、初始化环境变量：
export MINIKUBE_WANTUPDATENOTIFICATION=false
export MINIKUBE_WANTREPORTERRORPROMPT=false
export MINIKUBE_HOME=$HOME
export CHANGE_MINIKUBE_NONE_USER=true
mkdir -p $HOME/.kube
touch $HOME/.kube/config
export KUBECONFIG=$HOME/.kube/config
4、启动minikube
curl -Lo kubeadm http://storage.googleapis.com/kubernetes-release/release/v1.10.0/bin/linux/amd64/kubeadm
curl -Lo kubelet http://storage.googleapis.com/kubernetes-release/release/v1.10.0/bin/linux/amd64/kubelet
sudo -E ./minikube start --vm-driver=none
--vm-driver=none (本身就是虚拟机，所以不需要将minikube再次安装到虚机里面，虚机中再安装虚机我的机器扛不住)
在这个过程中minikube需要下载kubelet、kubeadm,以及拉取所需要到镜像，由于防火墙到原因，这就卡住了，再也不能进行下去了，所以啊，我挨个再国外服务器上拉取到镜像和程序包。
运行一下上面curl两句下载命令，不然会报错，因为下载kubeadm、kubelet时采用的是https，但是无法连接，使用http下载以后就可以跳过
Starting local Kubernetes v1.10.0 cluster...
Starting VM...
Getting VM IP address...
Moving files into cluster...
Downloading kubeadm v1.10.0
Downloading kubelet v1.10.0
这块了，不然会报一下这个错：
E0702 15:58:46.347477 20746 start.go:252] Error updating cluster: downloading binaries: downloading kubeadm: Error downloading kubeadm v1.10.0: failed to download: failed to download to temp file: download failed: 5 error(s) occurred:

以下是所需要的镜像列表：
k8s.gcr.io/kube-apiserver-amd64:v1.10.0
k8s.gcr.io/kube-scheduler-amd64:v1.10.0
k8s.gcr.io/kube-controller-manager-amd64:v1.10.0

k8s.gcr.io/k8s-dns-sidecar-amd64:1.14.8
k8s.gcr.io/k8s-dns-kube-dns-amd64:1.14.8
k8s.gcr.io/pause-amd64:3.1
quay.io/coreos/flannel:v0.9.1-amd64

k8s.gcr.io/kubernetes-dashboard-amd64:v1.8.1
gcr.io/k8s-minikube/storage-provisioner:v1.8.1
如果不出意外应该就可以安装成功了！
安装完成后
root@ubuntu:~# sudo -E ./minikube start --vm-driver=none

5、查看状态
查看node节点状态
root@ubuntu:~/1.10.1# kubectl get nodes
NAME STATUS ROLES AGE VERSION
minikube Ready master 20h v1.10.0
查看pod状态
root@ubuntu:~/1.10.1# kubectl get pods--all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system etcd-minikube 1/1 Running 2 1h
kube-system kube-addon-manager-minikube 1/1 Running 1 20h
kube-system kube-apiserver-minikube 1/1 Running 1 1h
kube-system kube-controller-manager-minikube 1/1 Running 2 1h
kube-system kube-dns-86f4d74b45-pndzp 3/3 Running 16 20h
kube-system kube-proxy-pgjpd 1/1 Running 0 1h
kube-system kube-scheduler-minikube 1/1 Running 5 20h
kube-system kubernetes-dashboard-5498ccf677-scd97 1/1 Running 4 18h
kube-system storage-provisioner 1/1 Running 1 18h
看下READY和STATUS状态，如果正常就一切ok，万事大吉了。
如果有问题，那就看看什么原因,例如查看dashboard，可以根据具体问题作出具体的解决方法（下面描述是没问题）
root@ubuntu:~# kubectl describe--namespace=kube-system pod kubernetes-dashboard-5498ccf677-scd97

6、启动dashboard
root@ubuntu:~# minikube dashboard
访问dashboard的是查看具体url：
root@ubuntu:~# minikube dashboard --url
http://10.0.3.15:30000
由于virtual是双网卡的问题，所以minikube返回的url是不能访问的，10.0.3.15这个IP是内部IP，pc端是无法访问的，所以需要在iptalbes上做一下路由转发！
临时：
echo "1">/proc/sys/net/ipv4/ip_forward
固定：修改/etc/sysctl.conf，取消这一行的注释：
net.ipv4.ip_forward= 1
root@ubuntu:~#sysctl -p
设置iptables规则：
iptables -t nat -A POSTROUTING -j MASQUERADE
再访问：http://192.168.56.102:30000就可以访问了
