Question

我尝试在 CentOS 7 中安装docker并出现守护程序错误。我尝试了Internet上用于安装和调试的所有方法，但没有一种有效！我什至尝试安装也不起作用的旧版Docker。

SELinux 已禁用。

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

很难为该问题提供确切的解决方案，而没有更多细节，但是，错误消息很明显：

在此主机上找不到
“覆盖”作为受支持的文件系统

请注意：

要配置Docker以使用覆盖存储驱动程序，您的Docker主机必须运行Linux内核的3.18版本（最好是较新的版本），并加载了重叠式内核模块。

使用uname -r

检查内核版本

如果自从安装docker以来已安装了新内核，请尝试重新引导计算机。

如果您不需要显式叠加，也可以在/etc/docker/daemon.json文件中指定存储驱动程序-“ devicemapper”是内核的首选存储驱动程序不支持重叠的广告。

CentOS 7-无法通过unix：///var/run/docker.sock连接到Docker守护程序。泊坞窗守护程序正在运行吗？
