无法启动Docker守护进程

我在CentOS 7中安装了docker，当我运行

[root@hk-qa-linux-2 ~]# docker daemon 

我得到以下

  INFO[0000] libcontainerd: new containerd process, pid: 611 ERRO[0001] 'overlay' not found as a supported filesystem on this host. Please ensure kernel is new enough and has overlay support loaded. INFO[0001] Graph migration to content-addressability took 0.00 seconds WARN[0001] Your kernel does not support cgroup memory limit WARN[0001] Unable to find cpu cgroup in mounts WARN[0001] Unable to find blkio cgroup in mounts WARN[0001] Unable to find cpuset cgroup in mounts WARN[0001] mountpoint for pids not found FATA[0001] Error starting daemon: Devices cgroup isn't mounted 

当我检查我的文件挂载时，我可以看到cgroup

 [root@hk-qa-linux-2 cgroup]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/loop6 61796348 689300 57944984 2% / none 100 0 100 0% /dev cgroup 12 0 12 0% /sys/fs/cgroup tmpfs 4032272 0 4032272 0% /sys/fs/cgroup/cgmanager tmpfs 4032272 0 4032272 0% /dev/shm tmpfs 4032272 8244 4024028 1% /run tmpfs 104860 0 104860 0% /run/user/0 

不知道如何解决这个问题。 任何build议都会有所帮助

 System details [root@hk-qa-linux-2 ~]# cat /etc/system-release CentOS Linux release 7.2.1511 (Core) [root@hk-qa-linux-2 ~]# uname -r 4.2.6-1-pve [root@hk-qa-linux-2 ~]# docker --version Docker version 1.12.0, build 8eab29e 

谢谢
