+# Centos网络源安装Containerd
+
+1. 设置存储库
+
+   [阿里源配置文件](https://developer.aliyun.com/mirror/docker-ce?spm=a2c6h.13651102.0.0.4eac1b11shXBpr)
+
+   ```bash
+   yum install -y yum-utils
+   yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
+   ```
+
+   > 国内
+   >
+   > ```bash
+   > yum install -y yum-utils
+   > yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
+   > ```
+
+2. 安装
+
+   ```bash
+   yum install -y containerd.io
+   ```
+
+3. 备份配置文件并使用默认配置文件
+
+   ```bash
+   mv /etc/containerd/config.toml /etc/containerd/config.toml.bak
+   containerd config default > /etc/containerd/config.toml
+   ```
+
+4. 修改驱动和镜像地址
+
+   ```bash
+   vi /etc/containerd/config.toml
+   ```
+
+   内容如下(已更新为最新版配置方法，旧版层级不同)
+
+   ```toml
+   [plugins]
+     ...
+     [plugins.'io.containerd.cri.v1.runtime'.containerd.runtimes.runc.options]
+       SystemdCgroup = true # 修改这里用于配置容器运行时使用 systemd 作为 cgroup 驱动 的关键设置
+   
+   [plugins.'io.containerd.cri.v1.images'.pinned_images]
+     sandbox = 'registry.aliyuncs.com/google_containers/pause:3.10.1'
+   ```
+
+5. 启动
+
+   ```bash
+   systemctl enable containerd
+   systemctl start containerd
+   systemctl status containerd
+   ```
+
+6. 验证
+
+   ```bash
+   ctr info
+   ```
+
+
