docker - 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/)。

我在 2 台 Ubuntu 14.04 机器上尝试过，在启动 docker daemon 时都出现以下错误:

$ sudo docker daemon
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) 
INFO[0000] [graphdriver] using prior storage driver "aufs" 
INFO[0000] Option DefaultDriver: bridge                 
INFO[0000] Option DefaultNetwork: bridge                
WARN[0000] Running modprobe bridge nf_nat br_netfilter failed with    message: modprobe: WARNING: Module br_netfilter not found. , error: exit status 1 
INFO[0000] Firewalld running: false                     
WARN[0000] Your kernel does not support cgroup memory limit: mountpoint for memory not found 
WARN[0000] mountpoint for cpu not found                 
FATA[0000] Error starting daemon: Devices cgroup isn't mounted 

感谢您为解决此问题提供的任何帮助。

我通过手动启动 docker 守护进程解决了这个问题:

sudo service docker start
