gbase8a中的资源管理

gbase8a中的常用配置方式：
每个点要root下环境变量
  ./SetSysEnv.py --dbaUser=gbase --installPrefix=/opt  --cgroup
 
               cgroup参数目的是初始化cgroup配置文件
                          [gbase@gbase-V9-191 ~]$ cat /etc/cgconfig.conf

                        # By default, mount all controllers to /cgroup/<controller>

                        mount {
                                cpu     = /cgroup/cpu;
                                cpuacct = /cgroup/cpuacct;
                                blkio   = /cgroup/blkio;
                                }

                        group gbase {
                                perm{
                                    task{
                                        uid = gbase;
                                        gid = gbase;
                                        }   
                                    admin{
                                        uid = gbase;
                                        gid = gbase;
                                        }   
                                    }
                                cpu{
                                    }
                                cpuacct{
                                    }
                                blkio{
                                    }   
                                }
              
另外：手动配置cgroup，可以参考如下步骤
 
 1）systemctl stop cgconfig.service
 
 2）查看挂载情况
 lssubsys -am
 
 [root@gbase-V9-191 ~]# lssubsys -am
    cpuset /sys/fs/cgroup/cpuset
    cpu,cpuacct /sys/fs/cgroup/cpu,cpuacct
    memory /sys/fs/cgroup/memory
    devices /sys/fs/cgroup/devices
    freezer /sys/fs/cgroup/freezer
    net_cls,net_prio /sys/fs/cgroup/net_cls,net_prio
    blkio /sys/fs/cgroup/blkio
    perf_event /sys/fs/cgroup/perf_event
    hugetlb /sys/fs/cgroup/hugetlb
    pids /sys/fs/cgroup/pids
 
 3）清除默认挂载信息  
 cgclear

 4）systemctl start cgconfig.service
 
 5）再次查看
 [root@gbase-V9-191 ~]# lssubsys -am
    cpuset
    memory
    devices
    freezer
    net_cls
    perf_event
    hugetlb
    pids
    net_prio
    cpu /cgroup/cpu
    cpuacct /cgroup/cpuacct
    blkio /cgroup/blkio
