Centos 6 to Centos 7 cgroups

Question

I'm trying to set up resource limits per user in Centos 7, but I can't find the right commands for the new implementation of cgroups (I did read the documentation but it talks about restricting services not users).

This are the steps in Centos 6

Add to /etc/cgconfig.conf

group mygroup{ cpu { cpu.shares = 200; } memory { memory.limit_in_bytes = 128m; } }
Restart service cgconfig restart
Start in system boot: chkconfig cgconfig on
Verify groups added correctly: lscgroup
Add the processes for which we wish to limit resources to the cgroups we created: add to /etc/cgrules.conf

myuser cpu,memory mygroup/
start the cgred service for the cgrules configuration changes to take effect: service cgred start
make sure the cgred service is enabled to start on system boot so that our rules persist across reboots: chkconfig cgred on

What is the equivalent in Centos 7?

@c4f4t0r I have no idea how to use the cgroup with systemd to replicate the steps above — Jesús Carrera, Dec 14 '15 at 08:14

Please try for example

systemctl set-property user-1000.slice CPUShares=100

Assuming you wish to limit the resource for UID 1000 and limit the CPUShares.

that method is considered deprecated and I'd like to know the new recommended way to do it in Centos 7 – Jesús Carrera Dec 27 '15 at 14:08
