2. 安装 Docker CE：
2.1 删除旧版本的 Docker（如果存在）：
sudo yum remove -y docker docker-common docker-selinux docker-engine
2.2 安装必要的软件包：
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
2.3 添加 Docker CE 存储库：
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
2.4 安装 Docker CE：
sudo yum install -y docker-ce
2.5 启动 Docker 服务：
sudo systemctl start docker
2.6 设置 Docker 开机自启：
sudo systemctl enable docker
3. 安装 NVIDIA Container Toolkit：
3.1 添加 NVIDIA Container Toolkit 存储库密钥：
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.repo | sudo tee /etc/yum.repos.d/nvidia-docker.repo
安装过程：
[xxx]# distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
[xxx]# curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.repo | sudo tee /etc/yum.repos.d/nvidia-docker.repo

4.1 创建或编辑 Docker 配置文件 /etc/docker/daemon.json
sudo nano /etc/docker/daemon.json
4.2 添加以下内容到文件中：
{"default-runtime": "nvidia","runtimes": {"nvidia": {"path": "nvidia-container-runtime","runtimeArgs": []}}
}
4.3 保存并关闭文件。
5. 重启 Docker 服务：
sudo systemctl restart docker
完成上述步骤后，您的 CentOS 系统将具备 NVIDIA Container Toolkit 的安装和配置。您可以使用带有 GPU 功能的 Docker 容器，并确保容器正确地使用 GPU 资源。
请注意，上述步骤适用于 CentOS 7 及更高版本。如果您使用的是其他版本的 CentOS，请参考 NVIDIA Container Toolkit 官方文档中针对您的 CentOS 版本的安装和配置指南。
