1. 检查是否存在显卡信息, 检查nvidia
$ lspci | grep -i nvidia
输出结果类似的情况如下：
02:00.0 3D controller: NVIDIA Corporation Device 1b38 (rev a1)
04:00.0 3D controller: NVIDIA Corporation Device 1b38 (rev a1)
83:00.0 3D controller: NVIDIA Corporation Device 1b38 (rev a1)
84:00.0 3D controller: NVIDIA Corporation Device 1b38 (rev a1)
检查os的版本信息
uname -m && cat /etc/*release
输出结果类似：
x86_64

uname -r 获取os版本
sudo yum install kernel-devel- (uname -r) 安装header
下载cuda toolkit安装包
download cuda-repo-rhel7-8.0.61-1.x86_64.rpm from the following url:
这里的是由于需要下载8.0的版本，目前最新的是9.1的版本。
参考资料： https://developer.nvidia.com/cuda-80-ga2-download-archive
下载最新的cuda-toolkit ， 请参阅：
https://developer.nvidia.com/cuda-downloads
然后安装，并更新cache
sudo rpm -i cuda-repo-rhel7-8.0.61-1.x86_64.rpm
sudo yum clean all
配置代理[optional]
vi /etc/yum.conf
在文件中新增：
proxy=http://192.168.1.1:8888
之后执行该配置文件：
source /etc/yum.conf
yum update
安装前置条件
yum install epel-release
yum install dkms
检查cuda是否在yum repository中
yum list | grep cuda
一般的输出结果为：
cuda-8-0.x86_64 8.0.61-1 @cuda
cuda-command-line-tools-8-0.x86_64 8.0.61-1 @cuda

..............进行cuda安装，选取特定的版本：
sudo yum install cuda-8-0.x86_64
配置环境变量[optional]
vi /etc/profile
在文件中新增：
export PATH=/usr/local/cuda-8.0/bin/:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-9.1/lib64:$LD_LIBRARY_PATH
生效配置信息：
source /etc/profile
检查环境变量是否生效：
echo $PATH
重启机器 [optional]
reboot now
重启机器是为了让各种配置生效，比如docker之类。比如碰到了如下错误信息：
46c1799eafe28c759582c5a60ded455d484d375e9e378b7c62d82bf8cf802e54

(exit status 1).总结
其中碰到了N多问题，不过这也是一个非常好的锻炼，发现问题，解决问题。
