centos 7 服务器安装nvidia显卡驱动和CUDA_centos cuda-repo-rhel7-10-2-local-10.2.89-440.33.0

# 查看本机显卡
lspci | grep -i nvidia

# 添加ELRpo源
# 1. 导入公钥
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
# 2. 添加源
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

# 安装显卡检查程序
yum -y install nvidia-detect
# 查找合适驱动, 一般是kmod-nvidia
nvidia-detect

# 安装kernel-devel依赖, 没有gcc的还要安装gcc
yum install -y kernel-devel-$(uname -r) kernel-headers-$(uname -r)

# 安装显卡驱动 install $(nvidia-detect)
yum -y install kmod-nvidia

# 重启
reboot

# 驱动安装完成
nvidia-smi

# 切换到tmp
cd /tmp/
# 下载cuda, 版本下载链接可去nvidia官网查
wget http://developer.download.nvidia.com/compute/cuda/10.2/Prod/local_installers/cuda-repo-rhel7-10-2-local-10.2.89-440.33.01-1.0-1.x86_64.rpm

# 安装cuda
rpm -i cuda-repo-rhel7-10-2-local-10.2.89-440.33.01-1.0-1.x86_64.rpm
yum clean all
yum -y install cuda

# 添加环境变量
export PATH=$PATH:/usr/local/cuda-10.2/bin
export LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64:$LD_LIBRARY_PATH

# 查看cuda是否安装成功
nvcc -V
