CentOS 7.6 + Nvidia显卡 + Cuda 10.2 + cuDNN 7.6

yum -y install epel-release gcc binutils wget kernel-devel kernel-headers
# 主要安装 kernel-devel，但是此处要保证内核于运行的一致，
# 两种解决思路：
# 1.找到对应版本的kernel-devel包
# 2.更新运行kernel（这里的例子采用此法）
yum -y install kernel
# 更改grub配置使用最新的内核启动
awk -F\' '$1=="menuentry " {print i++ " : " $2}' /etc/grub2.cfg
0 : CentOS Linux (3.10.0-1160.66.1.el7.x86_64) 7 (Core)
1 : CentOS Linux (3.10.0-957.el7.x86_64) 7 (Core)
2 : CentOS Linux (0-rescue-e0830d43d81340eb9b9f97a07371fc82) 7 (Core)
#将CentOS Linux （3.10.0-1160) 设置为默认启动项，对应的序号是0：

grub2-set-default 0
grub2-mkconfig -o /boot/grub2/grub.cfg
#重启机器
reboot
#内核更新了：
# 再次进入系统后
# uname -r
3.10.0-1160.66.1.el7.x86_64

lspci |grep -i VGA
# -bash: lspci: 未找到命令
# yum install pciutils

# 1. 检查是否开启Nouveau
lsmod | grep nouveau
# 注意：无信息输出表示已被禁用无需在操作以下步骤；

# 2. 修改配置
echo -e "blacklist nouveau\noptions nouveau modeset=0" > /etc/modprobe.d/blacklist.conf

# 3. 备份img
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak

# 4. 重建
dracut /boot/initramfs-$(uname -r).img $(uname -r)


# 5. 重启系统
reboot

# 6. 查看nouveau是否启动，如果结果为空即为禁用成功
# 同1.

 ./NVIDIA-Linux-x86_64-470.63.01.run
 # 之后按默认的回车即可
