yum -y install gcc kernel-devel "kernel-devel-uname-r == $(uname -r)" dkms "kernel-devel-uname-r == $(uname -r)"
修改/etc/modprobe.d/blacklist.conf 文件：
如果存在blacklist.conf，添加blacklist nouveau，注释掉blacklist nvidiafb；
如果不存在，执行：
echo -e "blacklist nouveau\noptions nouveau modeset=0" > /etc/modprobe.d/blacklist.conf
//修改运行级别为文本模式,无桌面环境可跳过此步
sudo systemctl set-default multi-user.target
//重新启动, 使用root用户登陆
reboot
查看操作系统的发行版号
uname -r
执行安装脚本
./NVIDIA-Linux-x86_64-450.57.run --kernel-source-path=/usr/src/kernels/3.10.0-1127.el7.x86_64 -k $(uname -r) --dkms -s
执行 nvidia-smi 看到以下信息说明安装成功
[root@localhost ~]# nvidia-smi
