1、系統信息
#使用centos7安裝系統作爲節點,安裝好系統先執行更新命令
yum -y update
#使用OVIRT節點ISO安裝系統，需要先更改更新源
我這裏使用的是163的更新源
Vi /etc/yum.repos.d/ CentOS7-Base.repo

CentOS-Base.repo

The mirror system uses the connecting IP address of the client and the

update status of each mirror to pick mirrors that are updated to and

geographically close to the client. You should use this for CentOS updates

unless you are manually picking other mirrors.

If the mirrorlist= does not work for you, as a fall back you can try the

remarked out baseurl= line instead.

清理更新緩存後更新系統
yum clean headers
yum clean packages
yum clean metadata
yum -y update
2、禁用centos自帶的顯卡驅動 nouveau
Vi /etc/modprobe.d/blacklist-nouveau.conf
blacklist nouveau
options nouveau modeset=0
給當前鏡像做備份
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak
建立新的鏡像
dracut /boot/initramfs-$(uname -r).img $(uname -r)
3、預安裝組件
yum install gcc kernel-devel kernel-headers –y
4、重啓系統
Reboot
lsmod | grep nouveau 沒有輸入則表示禁用成功
5、升級內核
升級內核需要先導入elrepo的key，然後安裝elrepo的yum源

rpm -import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

yum -y --enablerepo=elrepo-kernel install kernel-ml.x86_64 kernel-ml-devel.x86_64
reboot
6、下載驅動並安裝
驅動需要使用企業用戶登陸激活PAK碼後下載，在官網的普通頁面下載的驅動安裝不了
關於如何註冊企業用戶，在授權郵件的附件裏都有鏈接，這裏我給出鏈接地址
https://nvid.nvidia.com/NvidiaUtilities/#/createNewuser
註冊好收到郵件，激活賬戶。
登陸企業用戶，登陸地址
https://nvid.nvidia.com/dashboard/

點擊許可門戶網站激活PAK碼

輸入PAK嗎激活
激活好後下載驅動

我這裏的系統是OVIRT NODE ISO安裝的，所以我要下載了這個驅動

下載好解壓，將NVIDIA-Linux-x86_64-430.27-vgpu-kvm.run這個文件上傳到服務器
安裝驅動並重啓
Sh ./ NVIDIA-Linux-x86_64-430.27-vgpu-kvm.run
