尝试卸载docker并重新安装它，但它引发了同样的错误，运行的docker守护程序可以有人帮助我。

Answer 1

docker要求的服务没有运行，因此，systemd不会启动docker。

尝试启动journalctl -f（不使用-u）查看所有单元日志，然后启动docker并仔细阅读日志，您可能会看到其他一些单元尝试启动和失败。

Answer 2

您可以通过运行找到docker无法启动的原因

/usr/bin/dockerd -H unix://

在我来说，这是Docker 18.09的Centos7的全新安装

要解决此问题，我必须升级到更新的内核，并删除当前的docker存储空间

rm -rf /var/lib/docker

然后docker开始工作

docker.service失败了。有关详细信息，请参阅“journalctl -xe”
