Kubelet启动报错mountpoint for cpu not found

安装金山weboffice的时候遇到这个报错：

W0326 09:24:05.317578   26430 server.go:614] failed to get the kubelet's cgroup: mountpoint for cpu not found.  Kubelet system container metrics may be missing.
W0326 09:24:05.319976   26430 server.go:621] failed to get the container runtime's cgroup: failed to get container name for docker process: mountpoint for cpu not found. Runtime system container metrics may be missing.
F0326 09:24:05.320034   26430 server.go:269] failed to run Kubelet: mountpoint for cpu not found

百度、google、bing之后发现解决办法：

mkdir /sys/fs/cgroup/cpu,cpuacct
mount -t cgroup -o cpu,cpuacct none /sys/fs/cgroup/cpu,cpuacct

经过测试，完美解决问题。
