安装Docker

打开控制台使用 uname -r命令来查看你当前的内核版本。
Docker 要求 Ubuntu 系统的内核版本高于 3.10 ，查看本页面的前提条件来验证你的Ubuntu版本是否支持 Docker 。
配置Docker的安装源
依次输入
sudo apt-get update

这个可能会有些耗时

sudo apt-get install apt-transport-https
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
sudo sh -c "echo deb https://get.Docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
安装Docker
sudo apt-get update
sudo apt-get install lxc-docker
启动Docker以及配置Docker开机启动
sudo apt-get install sysv-rc-conf
sudo sysv-rc-conf docker on
sudo service docker restart

安装Docker Compose

分两个步骤：
curl -L https://github.com/docker/compose/releases/download/1.3.1/docker-compose-'uname -s'-'uname -m' > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

注意：如果你在安装的时候出现了 “Permission denied” 的错误信息，这说明你的 /usr/local/bin
目录是不可写的，你需要使用超级用户来安装。运行sudo -i , 然后运行上边的两个命令，然后 exit 退出。

到这里安装就结束了；Compose已经安装完成。你可以使用docker-compose --version 来进行测试安装是否成功。

Docker常用指令

Docker服务(开始/状态查看/停止/重启）
