# 手动运行服务器 { #run-a-server-manually }

## 使用 `fastapi run` 命令 { #use-the-fastapi-run-command }

简而言之，使用 `fastapi run` 来运行您的 FastAPI 应用程序：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting production server 🚀

             Searching for package file structure from directories

Перед розгортанням переконайтеся, що ви увійшли:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Потім розгорніть ваш застосунок:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

Now start Traefik:

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

And now start your app, using the `--root-path` option:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

이미 **FastAPI Cloud** 계정이 있다면(대기자 명단에서 초대해 드렸습니다 😉), 한 번의 명령으로 애플리케이션을 배포할 수 있습니다.

배포하기 전에, 로그인되어 있는지 확인하세요:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

그 다음 앱을 배포합니다:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

然後 Traefik 會把它的請求轉發到在 `http://127.0.0.1:8000` 上運行的 Uvicorn。

現在啟動 Traefik：

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

然後啟動你的應用，使用 `--root-path` 選項：

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>

It also comes included when you install the `all` extras with:

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

먼저 [가상 환경](../virtual-environments.md)을 만들고 활성화한 다음, `pydantic-settings` 패키지를 설치하세요:

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>

또는 다음처럼 `all` extras를 설치하면 함께 포함됩니다:

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

### `Settings` 객체 만들기 { #create-the-settings-object }

<div class="termy">

```console
$ pip install pytest

---> 100%
```

</div>

It will detect the files and tests automatically, execute them, and report the results back to you.

Run the tests with:

<div class="termy">

```console
$ pytest

================ test session starts ================

## 运行代码 { #run-the-code }

所有代码片段都可以复制后直接使用（它们实际上是经过测试的 Python 文件）。

要运行任何示例，请将代码复制到 `main.py` 文件中，然后启动 `fastapi dev`：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting development server 🚀

We need to install `PyJWT` to generate and verify the JWT tokens in Python.

Make sure you create a [virtual environment](../../virtual-environments.md), activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>
