### 单独的程序

为了实现这一点，您通常会有一个**单独的程序**来确保您的应用程序在启动时运行。 在许多情况下，它还可以确保其他组件或应用程序也运行，例如数据库。

### 启动时运行的示例工具

可以完成这项工作的工具的一些示例是：

* Docker
* Kubernetes
* Docker Compose
* Docker in Swarm Mode
* Systemd
* Supervisor
* 作为其服务的一部分由云提供商内部处理
* 其他的...

我将在接下来的章节中为您提供更具体的示例。


## 重新启动

与确保应用程序在启动时运行类似，您可能还想确保它在挂掉后**重新启动**。
