what's up ? docker, all right.

Docker install

下载对应安装包，离线安装 Docker 需要 docker-engine、docker-engine-selinux、libtool-ltdl这三个软件包。

下面以安装 Docker 1.12.6 为例讲讲如何在离线环境中安装 Docker，首先我们要下载对应的 Docker 软件包，下面的地址是官方提供的软件仓库地址，里面有各个版本的 Docker 软件包。

# CentOS
https://yum.dockerproject.org/repo/main/centos/

# Ubuntu
https://apt.dockerproject.org/repo/pool/main/d/docker-engine/

Docker 安装需要依赖 libtool-ltdl 软件包，libtool-ltdl可在pkgs.org这个网站搜索下载。

• 在 CentOS 7 下安装

$ mkdir docker_install
$ cd docker_install
$ wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-1.12.6-1.el7.centos.x86_64.rpm
$ wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-selinux-1.12.6-1.el7.centos.noarch.rpm
$ wget http://mirror.centos.org/centos/7/updates/x86_64/Packages/libtool-ltdl-2.4.2-22.el7_3.x86_64.rpm
$ rpm -ivh *.rpm

• 在 Ubuntu 14.04 下安装

$ mkdir docker_install
$ cd docker_install
$ wget https://apt.dockerproject.org/repo/pool/main/d/docker-engine/docker-engine_1.12.6-0~ubuntu-trusty_amd64.deb
$ wget http://archive.ubuntu.com/ubuntu/pool/main/libt/libtool/libltdl7_2.4.2-1.7ubuntu1_amd64.deb
$ dpkg -i *.deb

• 验证 Docker 是否安装成功
