以 15s 的检测间隔, 动态占用15%~20%的内存使用量.
(如果检测已使用超过 15%~20% 的内存, 则不占用内存)

删除 /run/shm/MemoryEat.bin 则自动停止占用内存, 直到下次重启服务.

wget -qO- https://github.com/MoeClub/Note/raw/master/Oracle/eat.service >/etc/systemd/system/eat.service

systemctl daemon-reload
systemctl enable eat
systemctl start eat

systemctl status eat       

systemctl disable eat
rm -rf /etc/systemd/system/eat.service
rm -rf /run/shm/MemoryEat.bin
