centos7 nvidia驱动安装失败问题的解决办法

 
 安装nvidia驱动日志出现“installing DKMS kernel module:
ERROR: Failed to run `/usr/sbin/dkms build -m nvidia -v 375.26 -k 3.10.0-862.3.2.el7.x86_64`: 
Kernel preparation unnecessary for this kernel.  Skipping...”

原因是安装了错误的模块。

查看安装的nvidia模块命令

rpm -qa|grep -i nvid|sort

删除找到的模块

yum  remove kmod-nvidia-390.87-1.el7_5.elrepo.x86_64  xorg-x11-drv-nvidia-384.81-1.el7.x86_64yum search  kmod-nvidia   nvidia-kmod-384.81-2.el7.x86_64

如果有错误提示“NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver”需要运行nvidia-uninstall

 

安装显卡检测程序

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

 yum install nvidia-detect  
 运行 nvidia-detect  

运行结果kmod-nvidia

安装基础包 yum install kernel-devel kernel-doc kernel-headers gcc\* glibc\*  glibc-\*

安装刚才检测到的驱动 yum install  kmod-nvidia
 然后查看显卡（命令：nvidia-smi）中进程的使用情况。
