# step 1: 装置必要的一些零碎工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 增加软件源信息
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3
sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
# Step 4: 更新并装置 Docker-CE
sudo yum makecache fast
sudo yum -y install docker-ce
# Step 4: 开启 Docker 服务
sudo service docker start

# 留神：# 官网软件源默认启用了最新的软件，您能够通过编辑软件源的形式获取各个版本的软件包。例如官网并没有将测试版本的软件源置为可用，您能够通过以下形式开启。同理能够开启各种测试版本等。# vim /etc/yum.repos.d/docker-ce.repo
#   将 [docker-ce-test] 下方的 enabled= 0 批改为 enabled=1
#
# 装置指定版本的 Docker-CE:
# Step 1: 查找 Docker-CE 的版本:
# yum list docker-ce.x86_64 --showduplicates | sort -r
#   Loading mirror speeds from cached hostfile
#   Loaded plugins: branch, fastestmirror, langpacks
#   docker-ce.x86_64            17.03.1.ce-1.el7.centos            docker-ce-stable
#   docker-ce.x86_64            17.03.1.ce-1.el7.centos            @docker-ce-stable
#   docker-ce.x86_64            17.03.0.ce-1.el7.centos            docker-ce-stable
#   Available Packages
# Step2: 装置指定版本的 Docker-CE: (VERSION 例如下面的 17.03.0.ce.1-1.el7.centos)
# sudo yum -y install docker-ce-[VERSION]

1、装置必要的一些零碎工具

yum install -y yum-utils device-mapper-persistent-data lvm2

2、增加软件源信息

yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

[root@centos yum.repos.d]# cat docker-ce.repo
[docker-ce-stable]

gpgcheck=1
gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg

[docker-ce-stable-source]
name=Docker CE Stable - Sources
baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/source/stable

3、配置 Docker -ce.repo 镜像

sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo

4、更新并装置 Docker-CE

sudo yum makecache fast
sudo yum -y install docker-ce

[root@centos yum.repos.d]# yum makecache fast

5、开启 Docker 服务

[root@centos yum.repos.d]# systemctl start docker
[root@centos yum.repos.d]# systemctl status docker

[root@centos yum.repos.d]# docker version
