centos7在线安装英伟达显卡驱动的方法

作者:互联网

1.查看是否含有英伟达显卡

#下面说明有四块英伟达的显卡
[admin@A01-R15-I47-118-0825868 http-cnn-rnn]$ lspci | grep -i NVIDIA
02:00.0 3D controller: NVIDIA Corporation Device 1b38 (rev a1)
03:00.0 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)

2.从ELRepo源安装显卡驱动(以下操作均以root权限运行)
ELRepo源提供了nvidia-detect命令,会自动帮你寻找合适的驱动,然后根据显示的结果,用yum就能完成安装,重启之后不会有任何问题,省时省力
2.1添加ELRepo源
2.1.1首先导入公共密钥

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

2.1.2安装ELRepo
http://elrepo.org/tiki/tiki-index.php

#centos7
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
#centos6
rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm  
#centos5
rpm -Uvh http://www.elrepo.org/elrepo-release-5-5.el5.elrepo.noarch.rpm 

2.2查找合适的驱动
2.2.1 安装nvidia-detect

yum install nvidia-detect 
2.2.2 运行nvidia-detect
[admin@A01-R15-I47-118-0825868 http-cnn-rnn]$ nvidia-detect
kmod-nvidia
WARNING: Xorg log file /var/log/Xorg.0.log does not exist
WARNING: Unable to determine Xorg ABI compatibility
WARNING: The driver for this device does not support the current Xorg version
#说明需要的驱动是最新的驱动 不用指定版本  默认下载最新的
[admin@A01-R15-I47-118-0825868 software]$ nvidia-detect -v
Probing for supported NVIDIA devices...
[10de:1b38] NVIDIA Corporation Device 1b38
This device requires the current 418.43 NVIDIA driver kmod-nvidia
[10de:1b38] NVIDIA Corporation Device 1b38
This device requires the current 418.43 NVIDIA driver kmod-nvidia
[1a03:2000] ASPEED Technology, Inc. ASPEED Graphics Family
[10de:1b38] NVIDIA Corporation Device 1b38
This device requires the current 418.43 NVIDIA driver kmod-nvidia
[10de:1b38] NVIDIA Corporation Device 1b38
This device requires the current 418.43 NVIDIA driver kmod-nvidia
WARNING: Xorg log file /var/log/Xorg.0.log does not exist
WARNING: Unable to determine Xorg ABI compatibility
WARNING: The driver for this device does not support the current Xorg version

根据 nvidia-detect 的输出信息,可以知道显卡的型号,以及要使用的驱动版本 418.43。
2.3安装显卡驱动
2.3.1 查找驱动程序

[admin@A01-R15-I47-118-0825868 http-cnn-rnn]$ yum search kmod-nvidia
Loaded plugins: fastestmirror, langpacks, nvidia
Determining fastest mirrors
 * elrepo: mirrors.tuna.tsinghua.edu.cn
========================================== N/S matched: kmod-nvidia ===========================================
kmod-nvidia.x86_64 : nvidia kernel module(s)
kmod-nvidia-340xx.x86_64 : nvidia-340xx kernel module(s)
kmod-nvidia-390xx.x86_64 : nvidia-390xx kernel module(s)

  Name and summary matches only, use "search all" for everything.

2.3.2 安装驱动程序

sudo yum install kmod-nvidia.x86_64

2.4 Disabling Nouveau

lsmod | grep nouveau 
#若没有输出 则说明禁用成功,否则执行下面的命令

Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:

blacklist nouveau
options nouveau modeset=0

Regenerate the kernel initramfs:

$ sudo dracut --force

2.5 重启

[admin@A01-R15-I47-118-0825868 software]$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver.
 Make sure that the latest NVIDIA driver is installed and running.

说明需要重新启动

reboot

2.6测试

[admin@A01-R15-I47-118-0825868 users]$ nvidia-smi
