centos 7 安装docker

CentOS 7 安装docker

不同centos 需要改动 配置中的值 如：name=CentOS-7、/centos/7对应系统版本

1.关防火墙

systemctl stop firewalld.service

2.进入 /etc/yum.repos.d 删除 CentOS-Base.repo 文件创建 CentOS-Base.repo 文件

cd /etc/yum.repos.d
rm -rf CentOS-Base.repo
touch CentOS-Base.repo

3.编辑 CentOS-Base.repo

[base]
name=CentOS-7 - Base
#mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=os&infra=$infra
baseurl=http://mirrors.aliyun.com/centos/7/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#released updates 
[updates]
name=CentOS-7 - Updates
#mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=updates&infra=$infra
baseurl=http://mirrors.aliyun.com/centos/7/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful
[extras]
name=CentOS-7 - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=extras&infra=$infra
baseurl=http://mirrors.aliyun.com/centos/7/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-7 - Plus
#mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=centosplus&infra=$infra
baseurl=http://mirrors.aliyun.com/centos/7/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

4.安装必要的依赖包

sudo yum install -y yum-utils

5.添加 Docker 官方 YUM 仓库

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

6.修改 /etc/yum.repos.d/docker-ce.repo 文件，将docker-ce-stable下的baseurl，gpgkey修改成如下的值

[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/7/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg

7.刷新缓存

sudo yum clean all
sudo yum makecache

8.安装 Docker

sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
