📚 CentOS7离线安装docker教程

1.拉取centos7镜像，并进入容器

docker run -it --name centos7 centos:7 bash
#连接中断再次进入
docker exec -it centos7 bash

2.安装必须工具，配置源

#启用阿里源
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo
yum clean all && yum makecache
yum -y install yum-utils

3.添加dockers镜像源

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

4.下载相关依赖的rpm包

yum install docker-ce --downloadonly --downloaddir=./docker

5.打包成一个tar包，方便传输

tar -czvf docker-CentOS7.9-rpm.tar.gz docker

6.运行scp命令传输到自己服务器

scp docker-CentOS7.9-rpm.tar.gz your-server-ip

7.解压tar包

tar zxvf docker-CentOS7.9-rpm.tar.gz

8.本地安装

yum -y localinstall docker/*.rpm

9.相关服务命令

# 右边默认演示系统不具有DBus,下面命令将不支持
# 查看状态
systemctl status docker 
# 启动docker
systemctl start docker 
# 重新启动docker
systemctl restart docker
# 重新加载unit配置文件
systemctl daemon-reload
# 设置开机
systemctl enable docker

10.直接下载rpm包安装,不推荐，可能会遇到依赖会失败
