安装Gbase8a时出现以下错误：
Environmental Checking on gcluster nodes.
Cgconfig service is not exist on host [‘192.168.48.18’, ‘192.168.48.19’, ‘192.168.48.20’], resource manangement can not be used, continue ([Y,y]/[N,n])?
检查以下安装包是否安装，如缺少请安装
yum list installed | grep libcgroup
yum list installed | grep libcgroup-tools
缺少则安装
yum -y install libcgroup
yum -y install libcgroup-tools
安装后设置cgroup服务开机启动
systemctl enable cgconfig.service
启动cgconfig服务
systemctl start cgconfig.service
这里如果执行报错：
Job for cgconfig.service failed because the control process exited with error code. See “systemctl status cgconfig.service” and “journalctl -xe” for details.
则使用命令查看报错原因
systemctl status cgconfig.service
如果原因如下：
Error: cannot mount cpu to /cgroup/cpu: Device or resource busy
或
Failed to start Control Group configuration service.
则执行
cgclear - unload the cgroup filesystem
systemctl start cgconfig.service
之后重新启动安装程序就可以了。
