在新主机上首次安装Docker Engine之前，需要设置Docker存储库。之后，您可以从存储库安装和更新Docker。
设置存储库
安装yum-utils软件包（提供yum-config-manager 实用程序）并设置稳定的存储库。
[root@localhost ~]# yum install -y yum-utils

添加下载地址：
yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo
安装DOCKER引擎
安装最新版本的Docker Engine和容器，或转到下一步以安装特定版本： 过程比较漫长 等等就好
yum install docker-ce docker-ce-cli containerd.io
如果提示您接受GPG密钥，请验证指纹是否匹配 060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35，如果是，则接受它。
不出意外 你会看到 成功两个字 ，
启动Docker。 systemctl start docker
别急 如果启动失败了 说明 版本问题导致的
你可以先卸载 再 继续安装 ，当然是选择性安装 根据版本号安装
要安装特定版本的Docker Engine，请在存储库中列出可用版本，然后选择并安装：
一个。列出并排序您存储库中可用的版本。此示例按版本号（从高到低）对结果进行排序，
[root@localhost lib]# yum list docker-ce --showduplicates | sort -r

b。通过其完全合格的软件包名称安装特定版本，该软件包名称是软件包名称（docker-ce）加上版本字符串（第二列），从第一个冒号（:）一直到第一个连字符，并用连字符（-）分隔。例如，docker-ce-18.09.1。
yum install docker-ce- docker-ce-cli- containerd.io
首先卸载之前的安装 （当然你也可以选择升级linux内核）
yum remove docker-ce docker-ce-cli containerd.io
rm -rf /var/lib/docker
执行完成后继续下面的执行
自定义安装
[root@localhost ~]# yum install docker-ce-17.09.1.ce

然后运行示例程序 在这之前 需要引入国内的镜像地址 当然你有翻墙 可以不要的
通过运行hello-world 映像来验证是否正确安装了Docker Engine 。
docker run hello-world
配置
/etc/docker 目录下创建 daemon.json
[root@localhost docker]# ll
总用量 8
-rw-r--r-- 1 root root 65 4月 7 22:50 daemon.json
-rw------- 1 root root 244 4月 7 22:33 key.json
然后里面的内容为
{ "registry-mirrors": ["https://alzgoonw.mirror.aliyuncs.com"] }
保存后 执行 测试命令
[root@localhost docker]# docker run hello-world

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:
