CentOS8快速安装Docker

Posted 2022-03-12 白-胖-子

• CentOS8 通过国内镜像源快速安装Docker-ce

1. 删除或者清理之前安装过的docker
   yum remove docker docker-common docker-selinux docker-engine
2. 安装必要的依赖和软件
   yum install -y yum-utils device-mapper-persistent-data lvm2 wget
3. 下载适合CentOS的docker镜像源repo文件
   wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo
4. 软件源仓库地址替换为国内清华软件源的地址:
   sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
5. 更新一下yum缓存
   yum makecache
6. 安装Docker-CE
   yum install docker-ce
7. 启动docker服务
   systemctl enable --now docker

[root@C8-196 ~]# systemctl enable --now docker
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.

• 写个小脚本放一起就行了

#!/bin/bash
yum remove docker docker-common docker-selinux docker-engine
yum install -y yum-utils device-mapper-persistent-data lvm2 wget
wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo
sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
yum makecache
yum install docker-ce
