无法使用 cgred 将用户的所有进程移入 cgroup

我在 CentOS 7.4 服务器上，并尝试设置 CGroups。

我的 cgconfig 如下所示：

#

mount {
    cpuset = /cgroup/cpuset;
}

group businesspro {
    cpu {
        cpu.shares="500";
    }
}

group startup {
    cpuset {
        cpuset.mems="0";
        cpuset.cpus="0";
    }
}

和 cgrules.conf：

# /etc/cgrules.conf
#The format of this file is described in cgrules.conf(5)
#manual page.
#
# Example:
#<user>     <controllers>   <destination>
#@student   cpu,memory  usergroup/student/
#peter      cpu     test1/
#%      memory      test2/
# End of file
#
@watchdra   cpu     businesspro/
*:iscsid net_prio cgdcb-4-3260
dramafor    cpuset      cpuset:/startup/

现在我想做的是将所有进程移到带有控制器的dramaforcgroup 中。我已经创建了它并重新启动了 cgconfig ，但文件是空的。我甚至不知道如何开始调试它。有人能告诉我出了什么问题吗，或者至少告诉我如何调试这种情况？startupcpusetcgredservicesstartup/tasks

好的，我找到了答案。在我的 cgred 中，我必须这样做，/startup而不是cpuset:/startup

对于遇到同样问题的人，简单的语法错误
