Linux 安装docker
首先我们创建一个目录赋予权限并进入该目录
代码语言：javascript复制vagrant@ubuntu-xenial:~$ sudo mkdir -m 775 -vp /data/www && cd /data/www
mkdir: created directory '/data'
mkdir: created directory '/data/www'安装docker本身
代码语言：javascript复制sudo wget -qO- https://get.docker.com | sh
或者
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解释一下命令的意思： sudo:_当前命令我希望用root用户执行_ wget:_是命令行的一个下载工具_ -qO-:_让wget标准输出_ | sh :_交给shell去执行_ 总的连起来:_以root用户身份用wget下载工具下载一个shell脚本文件标准输出交给sh执行_
代码语言：javascript复制vagrant@ubuntu-xenial:/data/www$ sudo wget -qO- https://get.docker.com | sh

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.允许非root用户运行docker
代码语言：javascript复制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 测试是否成功
代码语言：javascript复制vagrant@ubuntu-xenial:/data/www$ docker info # 测试是否可以打印出docker信息
