## Multiple Workers { #multiple-workers }

You can start multiple workers with the `--workers` command line option:

//// tab | `fastapi`

If you use the `fastapi` command:

<div class="termy">

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

### 安裝 `pydantic-settings` { #install-pydantic-settings }

首先，請先建立你的[虛擬環境](../virtual-environments.md)，啟用它，然後安裝 `pydantic-settings` 套件：

<div class="termy">

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

</div>

當你用 `all` extras 安裝時，它也會一併包含在內：

<div class="termy">

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

</div>

### 建立 `Settings` 物件 { #create-the-settings-object }

Antes de desplegar, asegúrate de haber iniciado sesión:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Luego despliega tu app:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

### 安装 `pydantic-settings` { #install-pydantic-settings }

首先，确保你创建并激活了[虚拟环境](../virtual-environments.md)，然后安装 `pydantic-settings` 包：

<div class="termy">

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

</div>

当你用以下方式安装 `all` 扩展时，它也会被一并安装：

<div class="termy">

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

</div>

### 创建 `Settings` 对象 { #create-the-settings-object }

And then we use it when creating the `FastAPI` app.

Then you could disable OpenAPI (including the UI docs) by setting the environment variable `OPENAPI_URL` to the empty string, like:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Before deploying, make sure you are logged in:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Then deploy your app:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

では Traefik を起動します:

<div class="termy">

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

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

</div>

次に、`--root-path` オプションを指定してアプリを起動します:

<div class="termy">

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

///

## 多個工作處理序 { #multiple-workers }

你可以用命令列選項 `--workers` 來啟動多個 workers：

//// tab | `fastapi`

如果你使用 `fastapi` 指令：

<div class="termy">

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

## Встановлення { #installation }

Створіть і активуйте [віртуальне середовище](https://fastapi.tiangolo.com/uk/virtual-environments/), а потім встановіть FastAPI:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

**Примітка**: переконайтеся, що ви взяли `"fastapi[standard]"` у лапки, щоб це працювало в усіх терміналах.

Vor dem Deployen, stellen Sie sicher, dass Sie eingeloggt sind:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Dann stellen Sie Ihre App bereit:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!
