   ```

2. 解压

   tar -zxvf cri-containerd-cni-*-linux-amd64.tar.gz -C containerd
   cd containerd
   ```

3. 移动文件至安装目录

   ```bash
   \cp usr/local/bin/* /usr/local/bin/

   mkdir /opt/cni/bin -p
   \cp /root/containerd/opt/cni/bin/* /opt/cni/bin/
   ```

4. 备份配置文件

   mkdir /etc/containerd
   containerd config default > /etc/containerd/config.toml

       SystemdCgroup = true #修改这里
