RHEL7 下控制服务的各种资源使用

RHEL7 和 RHEL6在控制资源的部分，具体的操作步骤有一些不同，操作想对简单，引入了新的概念slice

下面具体举例子说明如何让某个服务使用客户自定义的slice

第一步：创建新的slice

vi /etc/systemd/system/system-cpuload.slice
[Unit]
Description=CPUload slice


[Slice]
CPUShares=256
CPUAccounting=yes

vi /etc/systemd/system/system-cpuload.slice

[Unit]

Description=CPUload slice

[Slice]

CPUShares=256

CPUAccounting=yes

第二步：修改服务的具体配置

mkdir /etc/systemd/system/cpuload.service.d
vim /etc/systemd/system/cpuload.service.d/10-slice.conf

[Service]
Slice=system-cpuload.slice

mkdir /etc/systemd/system/cpuload.service.d

vim /etc/systemd/system/cpuload.service.d/10-slice.conf

[Service]

Slice=system-cpuload.slice

第三步：测试

sudo systemctl daemon-reload
sudo systemctl restart cpuload.service
sudo systemctl status cpuload | grep cgroup

sudo systemctl daemon-reload

sudo systemctl restart cpuload.service

sudo systemctl status cpuload | grep cgroup
