2、安装依赖包:
yum install -y yum-utils device-mapper-persistent-data lvm2
3、设置安装源(阿里云):
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

8、测试:

9、安装docker-compose(可选):
命令里的版本号可以去这里查找最新的:https://github.com/docker/compose/releases
sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-Linux-x86_64" -o /usr/local/bin/docker-compose sudo chmod +x /usr/local/bin/docker-compose sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
测试docker-compose:
docker-compose --version
