1.1.命令
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
1.2.sample
[root@izwz91h49n3mj8r232gqwez ~]# sudo yum install -y yum-utils device-mapper-persistent-data lvm2
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Package yum-utils- 2.新增軟體源資訊
2.1.命令
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
2.2.sample
[root@izwz91h49n3mj8r232gqwez ~]# sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror
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.repo
3.更新 yum 快取
sudo yum makecache fast

[root@izwz91h49n3mj8r232gqwez ~]#
4.安裝 Docker-ce
sudo yum -y install docker-ce
[root@izwz91h49n3mj8r232gqwez ~]# sudo yum -y install docker-ce
Loaded plugins: fastestmirror

Package 3:docker-ce-18.09.0-3.el7.x86_64 already installed and latest version
Nothing to do
5.啟動 Docker 後臺服務
sudo systemctl start docker
[root@izwz91h49n3mj8r232gqwez ~]# sudo systemctl start docker
6.測試驗證 測試執行 hello-world
[root@izwz91h49n3mj8r232gqwez ~]# docker run hello-world
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

由於本地沒有hello-world這個映象，所以會下載一個hello-world的映象，並在容器內執行。
