Docker 服务无法在 CentOS 7 上启动

我使用以下命令在 CentOS Linux 版本 7.6.1810 (Core) 上安装 Docker CE

yum check-update
curl -fsSL https://get.docker.com/ | sh

systemctl start docker 显示

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

journalctl -u docker.service 显示以下日志

在 Docker 论坛上提出了一个类似的问题，但目前还没有答案。
