执行下面命令检查服务器是否开启虚拟化技术

			
egrep --color 'vmx|svm' /proc/cpuinfo
			
			

如果没有任何输出，请重启服务器进入 BIOS 启用 VT-X 或 AMD-v

			
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 \
  && install minikube-linux-amd64 /usr/local/bin/minikube		 	
			
			

尝试运行 minikube 如果输出帮助信息表示安装成功

			
[root@localhost ~]# minikube version

有些老系统可能不支持 hyperkit，需要virtualbox。

			
$ brew cask install virtualbox
$ minikube start —vm-driver=virtualbox
$ minikube dashboard			
			
			

检查 minikube 启动状态
