centos 安装docker
安装依赖
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install docker-ce docker-ce-cli containerd.io
如果报错:Problem: package docker-ce-3:19.03.4-3.el7.x86_64 requires containerd.io >= 1.2.2-3 那就先装新版的 containerd.io
dnf install https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
再装剩下两个
sudo yum install docker-ce docker-ce-cli
sudo systemctl start docker
docker --version
开机自启
sudo systemctl enable docker
