### 3.配置Docker加速器 ###

Docker Hub 提供众多镜像，你可以从中自由下载数十万计的免费应用镜像， 这些镜像作为 docker 生态圈的基石，是我们使用和学习 docker 不可或缺的资源。为了解决国内用户使用 Docker Hub 时遇到的稳定性及速度问题 DaoCloud 推出永久免费的新一代加速器服务。

Linux：

curl -sSL https://get.daocloud.io/daotools/set\_mirror.sh | sh -s http://bc437cce.m.daocloud.io

[root@VM_0_3_centos ~]# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://bc437cce.m.daocloud.io
    docker version >= 1.12
    { "registry-mirrors": ["http://bc437cce.m.daocloud.io"]}
    Success.
    You need to restart docker to take effect: sudo systemctl restart docker 
    [root@VM_0_3_centos ~]# systemctl restart docker
    [root@VM_0_3_centos ~]# systemctl stop docker
    [root@VM_0_3_centos ~]# ps -ef|grep docker
    root     28185 25973  0 13:02 pts/0    00:00:00 grep --color=auto docker
    [root@VM_0_3_centos ~]# systemctl start docker
