虚拟机centos安装docker

1.先修改yum源 , 如果yum源不行, 后面会缺少软件包(后面的错误基本都是因为这个地方配置的不对)

sudo vi /etc/yum.repos.d/CentOS-Base.repo

[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY.cnpmjs.org
enabled=1

[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.aliyun.com/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY.cnpmjs.org
enabled=1

[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.aliyun.com/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY.cnpmjs.org
enabled=1

2.删除本地docker

sudo yum remove docker \
                docker-client \
                docker-client-latest \
                docker-common \
                docker-latest \
                docker-latest-logrotate \
                docker-logrotate \
                docker-engine

3.安装依赖

sudo yum update -y && sudo yum install -y yum-utils \
    device-mapper-persistent-data \
    lvm2

4.配置镜像源

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

5.安装

yum -y install docker-ce

6.验证

docker --version

7.完成

[root@localhost ~]# docker --version
Docker version 26.1.4, build 5650f9b
