2、确保CentOS7的PIC以太网已连接

3、yum安装gcc相关
yum -y install gcc

4、卸载旧版本(如果有)

6、设置stable镜像仓库
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

7、更新yum软件包索引
yum makecache fast

8、安装DOCKER CE(社区版)
yum -y install docker-ce

9、启动docker
systemctl start docker

10、测试
docker version
docker run hello-world

11、配置镜像加速
vim  /etc/docker/daemon.json

    #网易云
    {"registry-mirrors": ["http://hub-mirror.c.163.com"]?}

    #阿里云
    {
     "registry-mirrors": ["https://{自已的编码}.mirror.aliyuncs.com"]
    }

systemctl daemon-reload
systemctl restart docker

12、卸载Docker(需要时)
systemctl stop docker
yum -y remove docker-ce
rm -rf /var/lib/docker

 

13、遇到的问题

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

解决方法:

把yum包更新到最新
sudo yum update
