配置：

系统：ubuntu版本6.04.5 linux内核版本：4.4.0

连接工具：PuTTy

一、配置源里的阿里云镜像仓库（从docker官网安装特别慢）

sudo vim /etc/apt/sources.list 将以下配置覆盖修改进去

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse

添加完后执行 sudo apt update 更新源

二、安装装一些必要工具

sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common

三、安装docker

1.安装gpe证书

curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

2.写入软件源

sudo add-apt-repository “deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable”

3.更新源

sudo apt-get -y update

4.查看可以安装的docker版本

apt-cache madison docker-ce

5.安装指定版本号docker

sudo apt-get -y install docker-ce=<版本号>，版本号是上一部第一个竖线和第二个竖线之间的

4.校验安装

apt-cache madison docker

安装完成
