cgconfig服务无法启动

Question

我已经引用了这篇文章：Centos cgconfig fails to start

我有一台centos 7机器。我已尝试在以下/etc/cgconfig.conf文件中注释并留在内存中：

mount {
        cpuset  = /cgroup/cpuset;
        cpu     = /cgroup/cpu;
        cpuacct = /cgroup/cpuacct;
        memory  = /cgroup/memory;
        devices = /cgroup/devices;
        freezer = /cgroup/freezer;
        net_cls = /cgroup/net_cls;
        blkio   = /cgroup/blkio;
}

我还手动创建了该目录结构。当我运行service cgconfig start时，systemctl status cgconfig.service给了我这个：

 cgconfig.service - Control Group configuration service
   Loaded: loaded (/usr/lib/systemd/system/cgconfig.service; disabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Tue 2017-03-14 20:27:40 EDT; 18s ago
  Process: 6713 ExecStart=/usr/sbin/cgconfigparser -l /etc/cgconfig.conf -L /etc/cgconfig.d -s 1664 (code=exited, status=101)

Mar 14 20:27:40 localhost.localdomain systemd[1]: Unit cgconfig.service entered failed state.
Mar 14 20:27:40 localhost.localdomain systemd[1]: cgconfig.service failed.

我也试过看/proc/mounts或许卸载cpu。

任何帮助启动cgconfig服务的帮助都会有所帮助。

Answer 1

$ lssubsys -a
cpu,cpuacct

如果是像“ cpu，cpuacct”这样的协子系统，则必须安装在同一层次结构（对于cg）中。

Answer 2

在 Ubuntu 上运行我可以通过安装提供 libcgmanager {的 daemon 解决同样的问题{1}}
