官方安装指导
安装步骤
1.确定你是CentOS7及以上版本
[root@docker ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
[root@docker ~]#
2.卸载旧版本
a.查看是否已安装docker
[root@docker ~]# rpm -qc docker
未安装软件包 docker
[root@docker ~]#
b.如何安装了卸载docker
yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine
3.通过yum安装gcc相关依赖包
- 如果安装较慢或者经常卡住，先进行第5步
yum install -y gcc yum install -y gcc-c++
执行后的效果
[root@docker ~]# yum install -y gcc

[root@docker ~]# 5.设置yum stable镜像仓库 （源）
以下提供几个国内仓库
1.备份源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2.配置源
- 下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/下
[root@docker ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.tencent.com/repo/centos7_base.repo
-bash: wget: 未找到命令
[root@docker ~]#
以上问题是没有安装wget，通过yum先安装wget就可以执行成功了
yum install -y wget
再次执行
[root@docker ~]# yum install -y wget

6.更新yum软件包索引
- 执行yum clean all清除原有yum缓存。
- 执行yum makecache（刷新缓存）或者yum repolist all（查看所有配置可以使用的文件，会自动刷新缓存）。

[root@docker ~]# docker run hello-worldHello 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 theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, which sent itto your terminal.To try something more ambitious, you can run an Ubuntu container with:$ docker run -it ubuntu bashShare 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/[root@docker ~]#
