centos7安装英伟达显卡驱动

没有特殊要求，就不要折腾centos系统的显卡驱动了！！！
昨天手贱安装显卡驱动，总算是折腾好了，现将过程简单记录于此，以便下次手贱查阅

1. 首先关闭[Secure BOOT]，开机时按F2（dell 台机），找到该选项，改为[Disable]

2. 添加ElRepo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

3.安装nvidia-detect，用于检查显卡 yum install nvidia-detect

1. 运行命令 nvidia-detect -v 返回结果：

[ranlk@ranlk ~]$ nvidia-detect -v
Probing for supported NVIDIA devices...
[10de:13bb] NVIDIA Corporation GM107GL [Quadro K620]
This device requires the current 390.67 NVIDIA driver kmod-nvidia
[8086:1912] Intel Corporation HD Graphics 530
An Intel display controller was also detected

注意这里的信息 [Quadro K620] 和390.67
下载 NVIDIA-Linux-x86_64-390.67.run

1. 安装前的一系列准备工作

yum -y update //若系统很久没跟新，这句可能耗时较长
yum -y groupinstall "GNOME Desktop" "Development Tools"
yum -y install kernel-devel

yum -y install epel-release
yum -y install dkms

1. 禁用nouveau

vim /etc/default/grub  #在“GRUB_CMDLINE_LINUX”中添加 rd.driver.blacklist=nouveau nouveau.modeset=0
grub2-mkconfig -o /boot/grub2/grub.cfg #生成配置
vim /etc/modprobe.d/blacklist.conf #打开（新建）文件，加入blacklist nouveau
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img
dracut /boot/initramfs-$(uname -r).img $(uname -r)   #更新配置，并重启
reboot

#开机后确认是否禁用
lsmod | grep nouveau  #应该返回空

2. 切到init3，开始安装 sh NVIDIA-Linux-x86_64-390.67.run 其中的一些选项可自行百度，至此安装完成

8.查看状态 nvidia-smi

[ranlk@ranlk ~]$ nvidia-smi

卸载：
方法1.用run包卸载 sh NVIDIA-Linux-x86_64-390.67.run --uninstall
方法2. 如果是用yum安装的，则需要命令yum list installed | grep nvidia找出安装的包，用yum remove把nvidi打头的删除。
