【docker openEuler 安装】

下载

根据个人需求选择指定的安装包

https://download.docker.com/linux/static/stable/x86_64/

将安装包放到root根目录下

将文件上传Linux系统并解压

tar -xvf  docker-27.3.1.tgz

解压文件移动到指定目录下

cp docker/* /usr/bin/

安装

1、安装Vim

输入rpm -qa|grep vim命令，发现CentOS上只装了vim的最小化安装。

rpm -qa|grep vim

输入yum -y install vim*命令安装vim

yum -y install vim*

vim安装成功后结果如下所示

2、安装docker

将docker注册为service 在/etc/systemd/system目录下创建 docker.service文件
创建文件

vim /etc/systemd/system/docker.service

写入数据
进入后复制数据，然后按【esc】,再输入 【:wq】即可保存退出
