阿里ECS GPU機型如何安裝驅動（系統：CentOS7.3 GPU：Nvidia P100)

一、配置DNS以及yum
1、配置DNS

[root@gpu-test-01 ~]# vim /etc/resolv.conf 
nameserver 223.5.5.5
nameserver 114.114.114.114
options timeout:2 attempts:3 rotate single-request-reopen
說明：我這里配置了兩個外部DNS 223.5.5.5以及114.114.114.114
[root@gpu-test-01 ~]# chattr +i /etc/reslov.conf

2、配置yum

[root@gpu-test-01 ~]# cd /etc/yum.repos.d/
[root@gpu-test-01 yum.repos.d]# rm -rf ./*
[root@gpu-test-01 yum.repos.d]# mv /etc/yum.repos.d/* /tmp
[root@gpu-test-01 yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@gpu-test-01 yum.repos.d]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
[root@gpu-test-01 yum.repos.d]# wget https://us.download.nvidia.cn/tesla/418.67/nvidia-diag-driver-local-repo-rhel7-418.67-1.0-1.x86_64.rpm
[root@gpu-test-01 yum.repos.d]# yum install nvidia-diag-driver-local-repo-rhel7-418.67-1.0-1.x86_64.rpm -y
[root@gpu-test-01 yum.repos.d]# mv nvidia-diag-driver-local-repo-rhel7-418.67-1.0-1.x86_64.rpm /tmp/

二、下載驅動包

1、下載P100/P4驅動：

[root@gpu-test-01 ~]# wget http://us.download.nvidia.com/tesla/396.44/NVIDIA-Linux-x86_64-396.44.run

2、下載內核開發包：

[root@gpu-test-01 ~]# wget https://buildlogs.centos.org/c7.1611.u/kernel/20170620132051/3.10.0-514.21.2.el7.x86_64/kernel-devel-3.10.0-514.21.2.el7.x86_64.rpm

3、下載cuda包：（如果使用yum來裝cuda-drivers，這一步也可以忽略）

[root@gpu-test-01 ~]# wget https://developer.nvidia.com/compute/cuda/9.1/Prod/local_installers/cuda_9.1.85_387.26_linux

三、配置信息

下載并安裝kernel對應版本的kernel-devel和kernel-header包

[root@gpu-test-01 ~]# rpm -ivh kernel-devel-3.10.0-514.21.2.el7.x86_64.rpm 
Preparing...                          ################################# [100%]
Updating / installing...
   1:kernel-devel-3.10.0-514.21.2.el7 ################################# [100%]
[root@gpu-test-01 ~]# sudo rpm -qa | grep $(uname -r)
kernel-headers-3.10.0-514.21.2.el7.x86_64
kernel-3.10.0-514.21.2.el7.x86_64
kernel-devel-3.10.0-514.21.2.el7.x86_64

說明：kernel-devel和kernel版本不一致會導致在安裝driver rpm過程中driver編譯出錯。您可以在實例里運行rpm –qa | grep kernel檢測版本是否一致。確認版本后，再重新安裝驅動。

[root@gpu-test-01 ~]# sh NVIDIA-Linux-x86_64-396.44.run
按照引導一路下一步：

驗證下是否安裝成功：

[root@gpu-test-01 ~]# nvidia-smi

到此驅動已經安裝完成。
