通用centos安装docker

https://docs.docker.com/engine/install/centos/

1、卸载旧版本

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

2、设置稳定库

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

3、启动夜间库（可选，似乎更稳定）

 sudo yum-config-manager --enable docker-ce-nightly

4、安装最新版

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

这步可能显示没包：

No package docker-ce available.
No package docker-ce-cli available.
No package containerd.io available.
No package docker-compose-plugin available.
#尝试用一下命令安装
yum install docker

5、启动并验证

sudo systemctl start docker

sudo docker run hello-world
