1. Linux 安装docker

    1. 首先我们创建一个目录赋予权限并进入该目录

      vagrant@ubuntu-xenial:~$ sudo mkdir  -m 775 -vp  /data/www  && cd /data/www
       mkdir: created directory '/data'
       mkdir: created directory '/data/www'
    2. 安装docker本身

      sudo wget -qO- https://get.docker.com | sh
      curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
      也可以使用国内 daocloud 一键安装命令:
      curl -sSL https://get.daocloud.io/docker | sh





      | sh :_交给shell去执行_


      vagrant@ubuntu-xenial:/data/www$ sudo wget -qO- https://get.docker.com | sh
      # Executing docker install script, commit: 26ff363bcf3b3f5a00498ac43694bf1c7d9ce16c
      + sudo -E sh -c apt-get update -qq >/dev/null
      + sudo -E sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -qq apt-transport-https ca-certificates curl >/dev/null
      + sudo -E sh -c curl -fsSL "https://download.docker.com/linux/ubuntu/gpg" | apt-key add -qq - >/dev/null
      + sudo -E sh -c echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable" > /etc/apt/sources.list.d/docker.list
      + sudo -E sh -c apt-get update -qq >/dev/null
      + [ -n  ]
      + sudo -E sh -c apt-get install -y -qq --no-install-recommends docker-ce >/dev/null
      + sudo -E sh -c docker version

      If you would like to use Docker as a non-root user, you should now consider
      adding your user to the "docker" group with something like:
        sudo usermod -aG docker vagrant
      Remember that you will have to log out and back in for this to take effect!
      WARNING: Adding a user to the "docker" group will grant the ability to run
               containers which can be used to obtain root privileges on the
               docker host.
               Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
               for more information.
    3. 允许非root用户运行docker

      vagrant@ubuntu-xenial:/data/www$ sudo usermod -aG docker vagrant  #修改用户组,把当前用户加到docker组里 
      vagrant@ubuntu-xenial:/data/www$ newgrp docker                    # 切换用户组
    4. 测试是否成功

      vagrant@ubuntu-xenial:/data/www$ docker info  # 测试是否可以打印出docker信息
