docker - CentOS 在尝试启用 docker 实例时一直在挂起

Question

我是Docker新世界。安装Docker并centOS-7持续面临以下错误。我docker-composed使用以下命令安装

我做了这里提到的一切：无法连接到 Docker 守护进程。docker 守护进程是否在此主机上运行？，但它对我来说没有 CentOs 盒子。

sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

结步

sudo chmod +x /usr/local/bin/docker-compose

下一步

sudo groupadd docker
sudo gpasswd -a $USER docker
sudo usermod -aG docker $USER
sudo usermod -aG docker $(whoami)
sudo systemctl enable docker.service

现在，当我执行最后一个命令时，即使 rebbot VM 没有起床，centOS 机器也会挂起。我无法 ping 到那台机器。

我已经发布了每个步骤的日志-
