通过yum源安装:

由于官网的yum源太慢，下面使用阿里云的Yum源进行安装

rm -rf /etc/yum.repos.d/*

#CentOS 7 安装docker依赖三个yum源:Base,Extras,docker-ce

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-

ce/linux/centos/docker-ce.repo

yum clean all

yum -y install docker-ce

systemctl enable --now docker

删除 docker

[root@centos7 ~]#yum remove docker-ce

#删除docker资源存放的相关文件

[root@centos7 ~]#rm -rf /var/lib/docker

范例: CentOS 7 基于阿里云的安装docker方法

阿里云说明: 

https://developer.aliyun.com/mirror/docker-ce?spm=a2c6h.13651102.0.0.3e221b11sUMKNV

# step 1: 安装必要的一些系统工具

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

# Step 2: 添加软件源信息

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

ce/linux/centos/docker-ce.repo

# Step 3: 更新并安装Docker-CE

yum makecache fast

yum -y install docker-ce

# Step 4: 开启Docker服务

service docker start

# 注意:

# 官方软件源默认启用了最新的软件，您可以通过编辑软件源的方式获取各个版本的软件包。例如官方并没有

将测试版本的软件源置为可用，您可以通过以下方式开启。同理可以开启各种测试版本等。

# vim /etc/yum.repos.d/docker-ee.repo

#  将[docker-ce-test]下方的enabled=0修改为enabled=1

#

# 安装指定版本的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

范例: 在CentOS 7上安装指定版本的docker

#  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: 安装指定版本的Docker-CE: (VERSION例如上面的17.03.0.ce.1-1.el7.centos)

yum -y install docker-ce-[VERSION]

#示例

[root@centos7 ~]#yum -y install docker-ce-19.03.12-3.el7

范例: 在CentOS 7上安装指定版本的docker

[root@centos7 ~]#cat /etc/redhat-release

CentOS Linux release 7.6.1810 (Core)

[root@centos7 ~]# ls /etc/yum.repos.d/
