Centos7離線安裝nvidia驅動的兩種方法

• 方法1 在nvida官網下載對應的驅動安裝
• 方法2 直接安裝cuda，安裝過程中cuda會自動安裝對應的nvida驅動(推薦)

方法1

1.首先查看機器是否具有GPU

[javis@node5 rpm_resource]$ lspci | grep -i nvidia
06:00.0 3D controller: NVIDIA Corporation GP100GL (rev a1)
81:00.0 3D controller: NVIDIA Corporation GP100GL (rev a1)

2.在官網下載對應的驅動http://www.nvidia.cn/Download/index.aspx?lang=cn

然後跳轉到下載頁面，下載 nvidia-diag-driver-local-repo-rhel7-390.30-1.0-1.x86_64.rpm

(PS:注意下面紅色的框內是安裝步驟，安裝後可以使用nvidia-smi命令)

3.安裝步驟建議使用官方的

Once you accept the download please follow the steps listed below 

i) `rpm -i nvidia-diag-driver-local-repo-rhel7-390.30-1.0-1.x86_64.rpm' 
ii) `yum clean all`
iii) `yum install cuda-drivers` 
iv) `reboot`

但這裏安裝的時候可能會遇到

Error: Package: 1:nvidia-kmod-390.30-2.el7.x86_64 (nvidia-diag-driver-local-390.30)Requires: dkms

下載安裝dkms-2.2.0.3-31.1.noarch.rpm即可解決問題

sudo rpm -vih dkms-2.2.0.3-31.1.noarch.rpm

4.測試是否安裝成功

[javis@node5 cuda_example]$ nvidia-smi

方法2

下載對應版本的cuda：https://developer.nvidia.com/cuda-downloads
比如我下載的爲Centos7版本的RPM包，下載後直接安裝

sudo rpm -i cuda-repo-rhel7-10-2-local-10.2.89-440.33.01-1.0-1.x86_64.rpm

安裝cuda的時候會自動安裝nvidia驅動，控制檯信息：

Installing the NVIDIA display driver...
Installing the CUDA Toolkit in /usr/local/cuda-9.1 ...

cudann安裝

下載地址：https://developer.nvidia.com/rdp/cudnn-archive

解壓cudann.tgz包後後運行：
sudo cp cuda/include/cudnn.h /usr/local/cuda/include
sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64
sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*
