yum方式安装Docker
1.查看Centos版本命令
[root@suzhongde suzhongde]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)这里CentOS Linux release 7.9.2009 (Core)的版本必须大于3.0
2.需要确保当前安装的CentOS系统可以上网
[root@suzhongde suzhongde]# ping www.baidu.com
PING www.a.shifen.com (163.177.151.109) 56(84) bytes of data.
64 bytes from 163.177.151.109 (163.177.151.109): icmp_seq=1 ttl=54 time=9.02 ms

64 bytes from 163.177.151.109 (163.177.151.109): icmp_seq=4 ttl=54 time=9.77 ms3.使用yum安装gcc相关依赖
# 在终端依次输入以下命令
yum -y install gcc
yum -y install gcc-c++4.如果以前安装过docker 请卸载它们以及相关的依赖项
# 在终端输入以下命令
yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine5.安装yum-utils包
[root@suzhongde suzhongde]# yum install -y yum-utils

Package yum-utils-1.1.31-54.el7_8.noarch already installed and latest version
Nothing to do6.设置稳定的存储库
[root@suzhongde suzhongde]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror, langpacks
adding repo from: http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
grabbing file http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo7.配置yum源之后更新软件包的索引

[root@suzhongde suzhongde]# docker run hello-world

2db29710123e: Pull complete
Digest: sha256:2498fce14358aa50ead0cc6c19990fc6ff866ce72aeb5546e1d59caac3d0d60f
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/
For more examples and ideas, visit:
https://docs.docker.com/get-started/12.如果执行docker run hello-world报错需要修改docker镜像源：因为docker默认的源为国外官方源可能出现连接超时所以会报错(下面这个就是例子)
[root@suzhongde suzhongde]# docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
See 'docker run --help'.13.我们需要把镜像源修改为国内的这下面随便选一个就行
阿里云
https://pee6w651.mirror.aliyuncs.com
中国科技大学
https://docker.mirrors.ustc.edu.cn
网易
http://hub-mirror.c.163.com
执行vim /etc/docker/daemon.json
[root@suzhongde suzhongde]# vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://alzgoonw.mirror.aliyuncs.com"]
}
设置完成后再终端输入systemctl daemon-reload(重载docker配置)
然后再次在终端输入systemctl restart docker(重启docker)
14.测试数据源是否修改成功
在终端输入docker info查看是否配置成功
[root@suzhongde suzhongde]# docker info

做完这里就可以尝试拉去镜像了-在终端输入docker run hello-world拉取镜像
