I see a post here: https://www.domjudge.org/pipermail/domjudge-devel/2015-March/001628.html But same. I did run the create_cgroups script. I see /cgroup/memory/domjudge and /cgroup/cpuset/domjudge, so that looks good. Before i change grup:
GRUB_CMDLINE_LINUX_DEFAULT="quiet cgroup_enable=memory swapaccount=1"
and reboot ok, no errors or anything. I chek kernel command line: cat /proc/cmdline But it show: BOOT_IMAGE=/boot/vmlinuz-4.4.0-1044-aws root=UUID=512611f4-b05a-4d8a-b743-438b71c5385d ro console=tty1 console=ttyS0

You should not install domjudge to /root, this is a home directory of root, need highest privilege. Move to /opt, /usr/local or somethink like that.

First, the very same warning as there applies: you should really *not* install DOMjudge as root, but as a normal user.
Then you can either change the permissions by running
chmod a+rx $HOME
or you can just copy the file instead:
cp $HOME/domserver/etc/apache.conf /etc/apache2/conf-available/domjudge.conf
