系统安装
系统版本： openEuler-22.03
1、离线安装
１、二进制方式安装
下载Docker离线二进制包：https://download.docker.com/linux/static/stable/x86_64/docker-20.10.18.tgz
2、软件安装
tar -zxvf docker-20.10.18.tgz
chmod +x docker/*
#将二进制文件拷贝到/usr/bin/
cp docker/* /usr/bin/
#注册到系统服务
vim /usr/lib/systemd/system/docker.service

2、在线安装
2.1、先在有网络的机器上做离线安装包
1）新增安装源
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
2）下载安装包
container-selinux 有时候会出现版本的问题，一起下载就行
yumdownloader --resolve docker-ce docker-ce-cli containerd.io
yumdownloader --resolve container-selinux
3）打包下载的安装包
tar cf docker-ce.offline.tar *.rpm
2.2、上传到离线主机，并安装
1）上传到离线主机上
tar xf docker-ce.offline.tar
2）安装docker
sudo rpm -ivh container-selinux*.rpm
sudo rpm -ivh --replacefiles --replacepkgs *.rpm
- 启动docker
sudo systemctl start docker
sudo systemctl enable docker
sudo usermod -aG docker $USER
