Docker在国内安装和Docker pull都很慢，马云爸爸给广大的docker爱好者提供了便利：不仅可以在各个linux操作系统快速安装最新版的Docker，还免费提供了一个docker加速器，让大家免于Q的阻碍。
接下来，我来说下Ubuntu16.04如何接受马云爸爸的优惠：

一.替换为阿里云源：

先在终端输入以下命令：

<span class="hljs-built_in">sudo</span> vi /etc/apt/sources.list

• 1

然后删除sources.list里面的全部内容，替换为以下内容：

deb http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial-backports main restricted universe multiverse
<span class="hljs-preprocessor">##测试版源</span>
deb http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial-proposed main restricted universe multiverse
<span class="hljs-preprocessor"># 源码</span>
deb-src http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial main restricted universe multiverse
deb-src http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial-security main restricted universe multiverse
deb-src http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial-updates main restricted universe multiverse
deb-src http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial-backports main restricted universe multiverse
<span class="hljs-preprocessor">##测试版源</span>
deb-src http://mirrors<span class="hljs-preprocessor">.aliyun</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial-proposed main restricted universe multiverse
<span class="hljs-preprocessor"># Canonical 合作伙伴和附加</span>
deb http://archive<span class="hljs-preprocessor">.canonical</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial partner
deb http://extras<span class="hljs-preprocessor">.ubuntu</span><span class="hljs-preprocessor">.com</span>/ubuntu/ xenial main

二.更新源和软件

<span class="hljs-built_in">sudo</span> apt-get update 更新源  
<span class="hljs-built_in">sudo</span> apt-get upgrade 更新软件

三.安装curl

apt-<span class="hljs-keyword">get</span> install curl

• 1

注意：如果这里提示包冲突：

下列软件包有未满足的依赖关系：
 curl : 依赖: libcurl3 (= <span class="hljs-number">7.35</span><span class="hljs-number">.0</span>-<span class="hljs-number">1u</span>buntu2<span class="hljs-number">.10</span>) 但是 <span class="hljs-number">7.47</span><span class="hljs-number">.0</span>-<span class="hljs-number">1u</span>buntu2<span class="hljs-number">.2</span> 正要被安装
E: 无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系。

先执行：

apt-<span class="hljs-keyword">get</span> remove libcurl3

• 1

然后执行：

apt-<span class="hljs-keyword">get</span> install curl

• 1

即可！
四.安装Docker
执行命令：

curl -sSL http://acs-public-mirror<span class="hljs-preprocessor">.oss</span>-cn-hangzhou<span class="hljs-preprocessor">.aliyuncs</span><span class="hljs-preprocessor">.com</span>/docker-engine/internet | sh -

• 1

即可安装最新版的Docker！
当然，如果你用了阿里云主机，直接在内网执行下面这个脚本即可：

curl -sSL http://acs-public-mirror<span class="hljs-preprocessor">.oss</span>-cn-hangzhou<span class="hljs-preprocessor">.aliyuncs</span><span class="hljs-preprocessor">.com</span>/docker-engine/intranet | sh -

• 1

安装完后会在结束时打印如下内容:

五.开启加速
打开阿里云docker镜像仓库，然后用自己的阿里账号登录，找到“加速器”，会有给自己的专属加速器。再用页面的提示开启加速即可！地址教程：https://cr.console.aliyun.com/#/accelerator，具体如下：

针对Docker客户端版本大于1.10的用户

您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器：

<span class="hljs-built_in">sudo</span> mkdir -p /etc/docker

<span class="hljs-built_in">sudo</span> tee /etc/docker/daemon.json &lt;&lt;-<span class="hljs-string">'EOF'</span>
{
  <span class="hljs-string">"registry-mirrors"</span>: [<span class="hljs-string">"你的专属加速地址"</span>]
}
EOF

<span class="hljs-built_in">sudo</span> systemctl daemon-reload
<span class="hljs-built_in">sudo</span> systemctl restart docker
