接下來，你可以在啟動伺服器時，將設定以環境變數傳入。舉例來說，你可以設定 `ADMIN_EMAIL` 與 `APP_NAME`：

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

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

</div>

/// tip

要為單一指令設定多個環境變數，只要用空白分隔它們，並全部放在指令前面即可。

///

	maxProcs := runtime.GOMAXPROCS(0)
	cpuProcs := runtime.NumCPU()
	if maxProcs < cpuProcs {

接下来，运行服务器，并把配置作为环境变量传入，例如你可以设置 `ADMIN_EMAIL` 和 `APP_NAME`：

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

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

</div>

/// tip | 提示

要为单个命令设置多个环境变量，只需用空格分隔它们，并把它们都放在命令前面。

///

pkg image/color, type Gray16 struct
pkg image/color, type Gray16 struct, Y uint16
pkg image/color, type Model interface { Convert }
pkg image/color, type Model interface, Convert(Color) Color
pkg image/color, type NRGBA struct
pkg image/color, type NRGBA struct, A uint8
pkg image/color, type NRGBA struct, B uint8
pkg image/color, type NRGBA struct, G uint8
pkg image/color, type NRGBA struct, R uint8

次に、設定を環境変数として渡してサーバーを実行します。たとえば、`ADMIN_EMAIL` と `APP_NAME` を次のように設定できます:

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

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

</div>

/// tip | 豆知識

1つのコマンドに複数の環境変数を設定するには、スペースで区切ってコマンドの前に並べます。

///

```console
$ pip install python-multipart
```

これは、**OAuth2**が `username` と `password` を送信するために、「フォームデータ」を使うからです。

///

例を実行します:

<div class="termy">

```console
$ fastapi dev

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

</div>
