写在前面

因为我每次上课都需要安装docker,老师又不发安装文件，每次都去查镜像地址太麻烦，因此写下此篇记录

安装

首先确保系统已经成功配置好yum镜像源

安装docker必要的yum包

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

设置docker的源为阿里云

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

安装docker

sudo yum install -y docker-ce

sudo yum install docker-compose-plugin

配置docker的国内镜像地址

sudo mkdir -p /etc/docker

sudo vi /etc/docker/daemon.json

{
  "registry-mirrors": [
    "https://docker.m.daocloud.io",
    "https://hub-mirror.c.163.com",
    "https://mirror.baidubce.com",
    "https://registry.docker-cn.com",
        "https://docker.1panel.live",
        "https://docker-0.unsee.tech",
        "https://docker.1panel.live",
        "https://registry.dockermirror.com",
        "https://docker.imgdb.de",
        "https://docker.m.daocloud.io",
        "https://hub.firefly.store",
        "https://hub.littlediary.cn",
        "https://hub.rat.dev",
        "https://dhub.kubesre.xyz",
        "https://cjie.eu.org",
        "https://docker.kejilion.pro",
        "https://docker.1panelproxy.com",
        "https://docker.hlmirror.com",
        "https://hub.fast360.xyz",
        "https://ghcr.io"
  ],
  "dns": ["8.8.8.8", "8.8.4.4"]
}

重启docker服务

sudo systemctl daemon-reload

sudo systemctl restart docker

基本安装工作完成

输入docker -v 如有输出代表安装成功
