香港服务器# systemctl show -p CPUShares httpd.service
CPUShares=1024
注意：各个服务的默认CPU分配份额=1024，你可以增加/减少某个进程的CPU分配份额。


# systemctl set-property httpd.service CPUShares=2000
# systemctl show -p CPUShares httpd.service
CPUShares=2000
注意：当你为某个服务设置CPUShares，会自动创建一个以服务名命名的目录（如 httpd.service），里面包含了一个名为90-CPUShares.conf的文件，该文件含有CPUShare限制信息，你可以通过以下方式查看该?件：
# vi /etc/systemd/system/httpd.service.d/90-CPUShares.conf
[Service]
CPUShares=2000
