我们已在Centos 7.x中安装了docker 17.12，安装完成后，在尝试启动docker服务时遇到错误。最初我尝试为systemctl docker start尝试启动，然后在尝试journalctl时获得更多输出信息，提示docker.service进入失败状态。
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:

最佳答案
您的日志中没有证据。
您会以官方方式重新安装吗？
$ curl -fsSL https://get.docker.com -o get-docker.sh
$ sh get-docker.sh
