一、需要能做到的基础操作

1.下载镜像：centos7.5 centos7.6 centos7.9

https://developer.aliyun.com/mirror/

2.自己尝试安装

3.docker wget

4.安装系统时候修改网络

OpenEuler linux 5.10的内核版本支持ARM 支持X86

ISO发布包
虚拟机镜像
容器镜像
嵌入式镜像
repo源
OpenEuler镜像下载地址 https://repo.openeuler.org/

更新软件包

dnf update功能等同于yum update

dnf install ukui -y

systemctl set-default graphical.target 重启reboot

三、安装docker

在线安装

wget http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo

cd /etc/yum.repos.d/

ls

yum install docker-ce -y

cd /var/run/

ls

rm -rf yum.pid

cd

yum install docker-ce -y

cat /etc/redhat-release

systemctl restart docker

docker version

history

离线安装

yum search ifconfig
