tar Cxzvf /usr/local containerd-2.2.1-linux-amd64.tar.gz   

编写启动 containerd 的service 文件

cat <<EOF | tee  /usr/local/lib/systemd/system/containerd.service

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.

重新加载 systemd 配置文件并设置 containerd 运行时为开机自启动

systemctl daemon-reload && systemctl enable --now containerd

安装 runc

runc 是一个根据 OCI 标准创建和运行容器的底层工具，它是 Docker、containerd 等容器技术的"心脏"，负责真正调用 Linux 内核特性来实现容器隔离。

install -m 755 runc.amd64 /usr/local/sbin/runc

安装 crictl 命令行工具

crictl 是一个为 CRI（容器运行时接口） 兼容的容器运行时提供的命令行工具 

#下载地址

tar -xzf crictl-v1.35.0-linux-amd64.tar.gz -C /usr/local/bin

创建 crictl 的配置文件

cat > /etc/crictl.yaml << EOF
runtime-endpoint: "unix:///var/run/containerd/containerd.sock"
image-endpoint: "unix:///var/run/containerd/containerd.sock"
timeout: 10
debug: false
