CentOS7安装nvidia-docker2
1.安装docker-ce
因为nvidia-docker2依赖docker-ce，所以得先安装docker-ce。
1.1 如果主机上已经安装了docker，则先运行如下命令卸载
service docker stop
yum remove docker1.2 安装yum管理依赖包
sudo yum install -y yum-utils device-mapper-persistent-data lvm21.3添加docker-ce仓库命令
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo如果报以下错误
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
File "/bin/yum-config-manager", line 135
except yum.Errors.RepoError, e:
^
SyntaxError: invalid syntax
则运行如下命令修改/bin/yum-config-manager中的配置
vi /bin/yum-config-manager按下 i 字母
把文件开头 #!/usr/bin/python -tt 改为 #!/usr/bin/python2 -tt再按下esc键，键入:wq!保存。最后再次执行添加docker-ce仓库命令
1.4 运行如下安装docker-ce命令
sudo yum install docker-ce docker-ce-cli containerd.io如果报以下错误
Transaction check error:
file /usr/bin/docker from install of docker-ce-cli-1:19.03.8-3.el7.x86_64 conflicts with file from package docker-common-2:1.13.1-109.gitcccb291.el7.centos.x86_64
file /usr/bin/dockerd from install of docker-ce-3:19.03.8-3.el7.x86_64 conflicts with file from package docker-common-2:1.13.1-109.gitcccb291.el7.centos.x86_64
Error Summary则先运行如下命令删除docker残余的组件
sudo yum erase docker-common-2:1.13.1-109.gitcccb291.el7.centos.x86_64再次运行安装docker-ce命令
1.5 开机启动/启动/查看状态
systemctl enable docker // 设置开机启动
systemctl start docker // 启动docker
systemctl status docker //查看状态
2.安装nvidia-docker2
2.1设置仓库
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.repo | \
sudo tee /etc/yum.repos.d/nvidia-docker.repo
2.2更新仓库中的key
DIST=$(sed -n 's/releasever=//p' /etc/yum.conf)
DIST=${DIST:-$(. /etc/os-release; echo $VERSION_ID)}
sudo yum makecache
2.3安装nvidia-docker2
sudo yum install nvidia-docker2
2.4 重新载入docker daemon的设定
sudo pkill -SIGHUP dockerd
2.5 测试是否安装成功
docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi
第一次运行会花几分钟下载组件，最后显示如下结果则表示安装成功
docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi
