CentOS7安装Docker备忘

1、如有旧版本先卸载

sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine

2、**设置存储库**：安装`yum-utils`包

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

3、安装docker

sudo yum install docker-ce docker-ce-cli containerd.io

4、启动docker，并设置为开机自启

systemctl start docker
systemctl enable docker
