Docker 17无法在Centos 7中启动

我们已经在Centos 7.x中安装了docker 17.12，安装完成后，我在尝试启动docker服务时遇到错误。最初，我尝试了

systemctl

docker start，然后在尝试

journalctl

时尝试了更多输出，它显示

docker.service

进入了失败状态

详情如下:

Docker :
17.12.1-ce , build 7390fc6

Command tried:
sudo systemctl start docker
journalctl -u docker.service

Expected Output:
Docker service should be started successfully

Actual output:

sudo dockerd——调试

在我的情况下，daemon.json中的配置无效
