在ubuntu 14.04上启动docker守护程序时出错(未安装设备cgroup)

Question

我按照docker说明安装并验证了docker安装(来自http://docs.docker.com/linux/step_one/).

我尝试了2台Ubuntu 14.04机器,在启动docker守护程序时我遇到了以下错误:

$ sudo docker daemon

INFO[0000] [graphdriver] using prior storage driver "aufs" 
INFO[0000] Option DefaultDriver: bridge

WARN[0000] mountpoint for cpu not found

感谢您解决此问题的任何帮助.

我通过手动启动docker deamon解决了这个问题:

sudo service docker start

Answer 2

请尝试以下方法:

• 以具有sudo权限的用户身份登录Ubuntu.
• 编辑/ etc/default/grub文件.

• 设置GRUB_CMDLINE_LINUX值如下:

  GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

• 保存并关闭文件.

• 更新GRUB.

  $ sudo update-grub

• 重新启动系统.

按照此.
