全新安装后无法连接到Docker守护程序 [英] Cannot connect to the Docker daemon after clean install

问题描述

我尝试在ubuntu 14.04上安装docker.安装后，我遇到了一些问题，您可以在这里阅读它们:安装后未找到docker安装问题文件

I tried to install docker on my ubuntu 14.04. After Installation I had some issues you can read them here: docker installation issue file not found after installation

安装现已完成，但是当我运行 docker ps -a 时，出现此错误:

Installation is done now but when I run docker ps -a I got this error:

无法通过unix:///var/run/docker.sock连接到Docker守护程序.docker守护程序正在运行吗?

我以为没问题，我开始了.所以我跑了/etc/init.d/docker start

I thought okay no problem I start it. So I ran /etc/init.d/docker start

什么都没有改变.在这种情况下有什么问题?

Nothing changed. What is the issue in this case?

推荐答案

3.13是一个相当老的内核.安装最新的稳定的标准内核(3.19版的内核已支持overlay FS).主要的阻止者是cgroup问题.Cgroup必须可用.

3.13 is a quite old kernel. Install latest stable stock kernel (kernel from 3.19 has support for overlay FS). The main blocker is cgroup issue. Cgroups must be available.

其他有用的提示:错误在ubuntu 14.04上启动docker daemon(未安装设备cgroup)
