# 启用 cgroups v1 兼容模式

### 背景说明

本教程适用于 **Ubuntu/Debian/Windows 等使用 GRUB 引导的系统**，通过修改 GRUB 内核参数 `systemd.unified_cgroup_hierarchy=0`，强制系统使用 cgroups v1 层级模式。

***

### 操作步骤

* 若您是**Windows**系统，请输入以下命令进入multipass虚拟机，再继续操作。 

  进入cmd命令行，输入：

  ```
  multipass shell ubuntu-pedge
  ```
* 若您是**Ubuntu/Debian**系统，则忽略此步骤

#### 1. 编辑 GRUB 配置文件

**命令操作**

```bash
sudo vim /etc/default/grub
```

**修改内容**

找到 `GRUB_CMDLINE_LINUX` 参数行，**追加**以下内容（保留原有参数，以空格分隔）：

```diff
- GRUB_CMDLINE_LINUX="..."
+ GRUB_CMDLINE_LINUX="... systemd.unified_cgroup_hierarchy=0"
```

**完整示例**

修改后的行可能类似（具体参数因系统而异）：

```bash
GRUB_CMDLINE_LINUX="quiet splash systemd.unified_cgroup_hierarchy=0"
```

**注意事项**

* 如果参数已存在，请勿重复添加
* 修改前建议备份原文件

***

#### 2. 生成新 GRUB 配置并重启

**更新 GRUB 配置**

```bash
sudo update-grub
```

此命令将生成 `/boot/grub/grub.cfg` 文件，使修改生效。

**重启系统**

```bash
sudo reboot
```

***

通过此教程，您已成功将 cgroups 切换至 v1 模式。
